Hair loss: understanding, preventing and finding the right solution

Introduction

Hair loss is a reality that affects millions of people around the world, and it doesn't just affect men. Many women face it too, often with embarrassment or taboo. Whether gradual, sudden, or linked to a specific situation, hair loss has a far deeper impact than simply aesthetics. Hair plays a central role in how we perceive ourselves and the image we project to others. When it thins, thins, or disappears, confidence can waver, sometimes leading to stress, embarrassment, or a loss of self-confidence.

It is estimated that approximately 50% of men experience androgenetic alopecia by the age of 50¹ and nearly 70% after the age of 70² . Among women, approximately 40% after the age of 40 experience significant hair loss³ , often diffuse. These figures show that hair loss is not an exception, but a common experience for a large part of the population.

The causes are numerous: heredity, hormonal imbalances, stress, nutritional deficiencies, medical treatments, and even external aggressions such as pollution and the use of overly aggressive products. While some of these causes can be addressed at the root through medical care or lifestyle adjustments, others require practical and rapid solutions to regain thicker hair and a positive self-image.

Today, several options exist:

• Medical treatments such as minoxidil or hair transplants.

• Natural approaches that focus on diet, supplements and a healthy lifestyle.

• Immediate cosmetic solutions , such as hair powders or prostheses, but also innovative alternatives such as Capii , which effectively camouflage thinning areas while providing a natural and long-lasting result.

👉 Hair loss isn't inevitable. In this guide, we'll explore the causes, bad habits to avoid, available medical, natural, and cosmetic solutions, and how Capii stands out as a simple, safe, and effective alternative for regaining confidence.

2. Understanding Hair Loss

Hair loss is a natural phenomenon: each person loses between 50 and 100 hairs per day⁴ as part of the normal hair renewal cycle. This process is healthy and necessary. However, when hair loss becomes more severe or the hair no longer grows back, it is called abnormal hair loss . Understanding the causes and types of hair loss is essential to take effective action.

2.1. The most common causes

a) Heredity (androgenetic alopecia)

It is the most common cause of hair loss. It is estimated that around 50% of men experience androgenetic alopecia by the age of 50, and up to 70% after the age of 70⁵ . In women, around 40% after the age of 40 are affected³ , with diffuse thinning rather than localized baldness.

b) Hormonal imbalances

Hormonal changes (pregnancy, postpartum, menopause, thyroid disorders) can lead to temporary or chronic hair loss. In men, excess DHT (dihydrotestosterone) contributes to the thinning and miniaturization of follicles⁶.

c) Stress and fatigue

Chronic stress is a recognized factor in sudden hair loss, called telogen effluvium . Many follicles prematurely enter the resting phase, leading to visible hair loss a few months later⁷.

d) Nutritional deficiencies

A diet lacking in essential nutrients weakens hair. The most common:

• Iron : essential for oxygenation of follicles⁸.

• Zinc : role in tissue growth and repair.

• Vitamin D : supports the hair cycle.

• Proteins : main component of keratin, the basis of hair.

e) Medical treatments

Chemotherapy, antidepressants, blood thinners, and certain hormone treatments are among the medications that can cause temporary but often significant hair loss⁹.

f) External aggressions

Pollution, sun, chlorinated water, repeated coloring or the use of overly aggressive products weaken the fiber and accelerate the wear of the follicles¹⁰.

2.2. The different types of loss

• Androgenetic alopecia : the most common. In men, it begins at the hairline or crown of the head. In women, it begins with a diffuse thinning of the central parting.

• Telogen effluvium : sudden hair loss, often after intense stress, childbirth or illness. Usually reversible⁷.

• Diffuse alopecia : overall loss of density without specific areas, common after the age of 40 in women.

• Scarring alopecia : Rare, caused by an autoimmune disease or severe inflammation. The loss is irreversible¹¹.

• Seasonal hair loss : more marked in spring and autumn, benign and temporary.

2.3. Psychological and social impact

Hair loss is not just a cosmetic problem. It directly affects:

• Self-confidence : Full hair is often associated with youth and vitality.

• Social life : Some people avoid photos, events or meetings.

• Mental health : anxiety, isolation, and even depression may appear.

According to a study published in the Journal of the American Academy of Dermatology (JAAD) , approximately 62% of men and 52% of women with alopecia report that their hair loss negatively affects their self-esteem¹² .
Additionally, a survey by the International Society of Hair Restoration Surgery (ISHRS) reveals that 70% of patients seek a hair solution primarily to improve their social and professional confidence¹³ .

2.4. Key statistics on hair loss

• 50% of men at age 50 have androgenetic alopecia⁵.

• This figure rises to 70% after age 70⁵ .

• 40% of women after age 40 experience significant loss³.

• In Canada, approximately 40% of men over the age of 35 are already showing signs of baldness¹⁴.

2.5. When should you be concerned?

It is normal to lose some hair every day. However, it is recommended to consult a dermatologist if:

• the fall is sudden and abundant;

• bald areas appear quickly;

• the scalp is red, irritated or itchy;

• hair grows back thinner and thinner.

Conclusion of Section 2

Hair loss is a universal phenomenon with multiple causes: genetic, hormonal, nutritional, environmental, and lifestyle-related. The good news is that today, there are a variety of solutions to slow, reduce, or conceal it.

👉 In the next section, we will see the aggravating factors to avoid in order to protect your hair and limit hair loss.

3. Aggravating factors to avoid

While some causes of hair loss are unavoidable, such as heredity or hormonal changes, others are directly linked to our lifestyle habits and environment. These aggravating factors accelerate hair loss or further weaken the fiber. Identifying and limiting them is an essential step in preserving your hair.

3.1. Bad hair habits

• Tight hairstyles : Ponytails, braids, buns, and extensions put excessive tension on the hair follicles. This condition, called traction alopecia , is especially common in people who regularly wear these types of hairstyles¹⁵.

• Straightening and chemical treatments : repeated straightening, perming or coloring weakens the hair fiber and damages the scalp¹⁶.

• Using harsh shampoos : Products containing sulfates and silicones can dry out and irritate the scalp, promoting breakage and hair loss¹⁷.

3.2. Stress and lack of sleep

Chronic stress is a recognized enemy of hair. It disrupts the hair growth cycle and can trigger telogen effluvium , where a large amount of hair prematurely enters the resting phase⁷. Lack of sleep, on the other hand, increases stress and reduces cell regeneration, directly affecting hair health¹⁸.

3.3. Bad lifestyle habits

• Tobacco : It reduces blood circulation to the scalp, depriving follicles of oxygen and essential nutrients¹⁹.

• Alcohol : consumed in excess, it leads to deficiencies in zinc, iron and B vitamins, essential for hair growth²⁰.

• Restrictive diets : diets too low in protein, iron or vitamins quickly weaken hair²¹.

3.4. External aggressions

• Pollution : Exposure to fine particles and heavy metals weakens follicles and increases oxidative stress²².

• Sun exposure : UV rays damage keratin and dry out the scalp²³.

• Chlorinated water : common in swimming pools, it irritates the scalp and weakens the fiber²⁴.

• Hard water (limescale) : it leaves deposits that make hair dry, brittle and dull²⁵.

3.5. The importance of correcting these factors

Limiting these habits and protecting your hair from external aggressions does not always stop hair loss of genetic or hormonal origin. But it can slow the process, improve the overall appearance of your hair and reinforce the results of other medical, natural or cosmetic solutions .

👉 In the next section, we will explore medical and professional solutions that can effectively treat or slow hair loss.

4. Medical and professional solutions

When hair loss becomes significant or persistent, it may require the advice of a dermatologist or hair specialist. These professionals can offer a variety of treatments, ranging from medications to surgical procedures. While some of these solutions require strict medical monitoring or significant financial investment, they represent an effective alternative for slowing or correcting hair loss.

4.1. Medicines

a) Minoxidil

Minoxidil is one of the most widely used treatments worldwide for androgenetic alopecia. Available in lotion or foam, it works by stimulating blood circulation in the scalp, which prolongs the hair growth phase²⁶.

• Effectiveness : visible results after 4 to 6 months of regular use.

• Limits : Must be applied continuously; stopping causes the fall to resume.

• Side effects : irritation, itching, sometimes temporary loss at first.

b) Finasteride

Finasteride is an oral medication prescribed primarily for men. It works by reducing the production of DHT (dihydrotestosterone) , a hormone responsible for the gradual thinning of follicles²⁷.

• Effectiveness : slows hair loss in 80 to 90% of men and promotes partial regrowth.

• Limitations : reserved for men; ineffective for women.

• Side effects : decreased libido, erectile dysfunction, rarely depression²⁸.

c) Other drug options

• Spironolactone : Sometimes used in women to block the action of androgens.

• Corticosteroids : local injections in cases of alopecia areata.

4.2. Hair transplant

Hair transplantation is one of the most sustainable solutions available today. It involves taking strong follicles from the back of the head and implanting them in the bald areas²⁹.

• Main techniques :

  • FUT (Follicular Unit Transplantation) : removal of a strip of scalp.

  • FUE (Follicular Unit Extraction) : single follicle extraction, more modern and less invasive.

• Effectiveness : natural and permanent results.

• Limitations : Expensive ($2,500 to $10,000 depending on country and scale).

• Popularity : Turkey has become a leading destination, with more than 500 specialized clinics and a rapidly expanding market³⁰.

4.3. Clinical treatments

a) PRP (Platelet Rich Plasma)

PRP involves drawing blood from the patient, centrifuging it to isolate the platelets, and then injecting it into the scalp. These platelets contain growth factors that stimulate follicle regeneration³¹.

• Effectiveness : Improves density and slows hair loss.

• Limitations : several sessions required, variable results.

b) Hair mesotherapy

Micro-injections of vitamins, minerals and amino acids to stimulate the scalp³².

• Effectiveness : nourishing and revitalizing effect.

• Limitations : results are mainly visible on weakened hair but are still present.

c) Low intensity laser

The laser stimulates circulation and reduces inflammation, promoting an environment conducive to regrowth³³.

• Effectiveness : improvement in hair density observed after several months.

• Limitations : adjunctive treatment, results vary depending on the patient.

4.4. When should you consult a specialist?

It is advisable to make an appointment with a dermatologist if:

• The fall is sudden and significant.

• Bald patches appear quickly.

• You have a family history of alopecia.

• Homemade or natural solutions do not provide any effect after several months.

Conclusion of Section 4

Medical and professional solutions are often effective, but they require strict monitoring and can represent a significant investment. For those who prefer a gentler or more complementary approach, natural and preventative alternatives exist.

👉 In the next section, we will see natural and preventive solutions , accessible to all and ideal for strengthening hair on a daily basis.

5. Natural and preventive solutions

While medications and hair transplants can produce significant results, many people prefer to start with gentler, more accessible solutions without major side effects. Natural and preventative approaches aim to strengthen the scalp, slow hair loss, and stimulate growth . They are not a substitute for medical treatment for severe alopecia, but they play an essential role in a healthy hair routine.

5.1. The importance of nutrition

A balanced diet is the first step to maintaining strong, healthy hair. Hair follicles are sensitive to deficiencies, and an unbalanced diet can accelerate their weakening³⁴.

• Protein : Essential because hair is made up of 95% keratin, a fibrous protein. Ideal sources are eggs, poultry, fish, and legumes.

• Iron : plays a role in oxygenating the follicles; a deficiency can lead to significant hair loss³⁵. It is found in red meat, lentils and spinach.

• Zinc : Promotes cell division and tissue repair³⁶. Found in nuts, oysters, and pumpkin seeds.

• B vitamins (B7 – Biotin, B12, B9) : support hair growth and pigmentation³⁷. Sources: whole grains, eggs, brewer’s yeast.

• Vitamin D : Contributes to the proper functioning of follicles³⁸. Found in oily fish, sun exposure, or as a supplement.

• Omega-3 : Provides elasticity and hydration; found in salmon, walnuts and flax seeds³⁹.

5.2. Food supplements

For those who struggle to meet their needs through food alone, dietary supplements can be a valuable aid.

• Biotin (vitamin B8) : widely used in anti-hair loss treatments, it strengthens keratin⁴⁰.

• Marine Collagen : Improves hair strength and elasticity⁴¹.

• Multivitamins : useful for compensating for deficiencies linked to stress, fatigue or poor diet.

⚠️ Caution: It is best to consult a professional before starting a treatment to avoid excesses or interactions with other treatments.

5.3. Beneficial oils and plants

Certain vegetable oils and plant extracts have long been recognized for their effectiveness on the scalp.

• Castor oil : rich in ricinoleic acid, it stimulates circulation and promotes growth⁴².

• Coconut Oil : Moisturizes and protects against breakage.

• Rosemary : Studies show that its essential oil can be as effective as minoxidil in some cases of mild alopecia⁴³.

• Nettle : remineralizing plant, often used in fortifying shampoos⁴⁴.

• Amla (Indian gooseberry) : rich in vitamin C and antioxidants, it strengthens the fiber and slows down hair aging⁴⁵.

5.4. Massage and stimulation of the scalp

Regular scalp massage stimulates blood circulation and delivers more nutrients to the follicles⁴⁶.

• Technique : circular movements with fingers or a massage brush, 5 minutes per day.

• Benefit : Reduces stress while promoting growth.

5.5. A gentle hair routine

• Sulfate-free shampoos : less aggressive and gentle on the scalp.

• Space out washes : 2 to 3 times per week to avoid drying out your hair.

• Limit heat : hair dryers, straighteners and irons damage keratin⁴⁷.

• Avoid coloring too frequently : this weakens the fiber and oxidizes it.

5.6. Stress management

As mentioned above, stress is a major aggravating factor. Relaxation practices such as yoga, meditation, deep breathing, and regular physical activity can help limit its effects⁷. Getting 7 to 8 hours of restful sleep per night is also essential for cell regeneration⁴⁸.

Conclusion of Section 5

Natural and preventative solutions provide a solid foundation for maintaining hair health. They do not always replace medical treatments, but they offer a comprehensive and complementary approach that benefits everyone.
👉 In the next section, we will see immediate cosmetic solutions , some of which are very widespread but limited… and how Capii stands out as an innovative alternative.

6. Immediate cosmetic solutions

When hair loss becomes noticeable, many people look for quick and affordable solutions. Unlike medical treatments or transplants, immediate cosmetic solutions don't address the root cause, but they offer quick and often stunning aesthetic results. They're a popular choice for those who want to regain confidence in their daily lives, without the need for medical commitment or excessive expense.

6.1. Hair powders

Hair powders are keratin or cotton microfibers that electrostatically attach to existing hair. They are widely used to camouflage thinning areas.

• Benefits :

  • Quick and easy application.

  • Natural appearance from a distance.

  • Inexpensive.

• Disadvantages :

  • Limited wear: disappears with rain, wind or perspiration⁴⁹.

  • May stain sheets, clothing or cushions.

  • Requires daily reapplication.

👉 In summary: a temporary solution that is effective in the short term, but unreliable for prolonged or active use.

6.2. Densifying sprays

Densifying sprays contain colored pigments or liquid fibers that coat the scalp to give a thickening effect.

• Benefits :

  • Immediate effect, visible camouflage.

  • Easy to apply.

• Disadvantages :

  • Often an artificial result when viewed up close.

  • Lack of durability (rarely last more than a day)⁵⁰.

  • Can dry out the scalp in the long term.

👉 Good for occasional use, but not ideal as a long-term solution.

6.3. Hair prostheses

Hair prostheses, also called wigs or hair pieces, cover the scalp completely or partially.

• Benefits :

  • Immediate and spectacular result.

  • Works even in cases of complete baldness.

• Disadvantages :

  • Expensive (from a few hundred to several thousand dollars).

  • Complex maintenance and possible discomfort⁵¹.

  • May slip or appear artificial in certain situations.

👉 Effective solution for advanced cases, but restrictive for daily use.

6.4. Other cosmetic alternatives

• Coloring shampoos : give the illusion of density but fade quickly.

• Implanted synthetic fibers (non-medical) : rarely used today due to irritation risks⁵².

6.5. Capii: the innovative alternative

Unlike traditional solutions, Capii offers a unique approach that combines natural results, long-lasting hold and safety .

• Easy application : just a few seconds are enough to transform your hair.

• Safety : Tested formula, safe for scalp and hair.

• Unisex : Designed for both men and women.

• Versatile color : Black blends perfectly with black and brown hair, for a discreet and effective look.

👉 Why choose Capii over other products?

• Longer lasting than hair powders.

• More natural than thickening sprays.

• More practical and accessible than prosthetics.

In short: Capii combines the best of cosmetic solutions without their major drawbacks .

Conclusion of Section 6

Instant cosmetic solutions offer a quick alternative to hair loss, but they often have significant limitations: lack of durability, artificial effect or maintenance constraints.
👉 Capii stands out as a modern and effective solution , offering a natural look, long-lasting hold and ease of use that meet the needs of today's men and women.

7. Practical tips to slow down loss

Although hair loss can have genetic or hormonal causes that are difficult to control, there are simple habits that can slow the process and maintain hair health . These tips are not a substitute for medical treatment if necessary, but they are an effective complement to any care approach.

7.1. Scalp massages

Regular massage stimulates blood circulation and promotes nutrient delivery to hair follicles. A Japanese study showed that a 4-minute massage per day for 24 weeks significantly increased hair thickness⁵³ .

• Technique : circular movements with fingertips or a massage brush.

• Frequency : 5 to 10 minutes per day.

• Benefits : Stimulates growth, relaxes and reduces stress.

7.2. Appropriate hair hygiene

• Gentle shampoos : choose formulas without harsh sulfates⁵⁴.

• Space out washes : 2 to 3 times a week is enough, because washing too often dries out and weakens the fiber.

• Warm water rather than hot : water that is too hot increases dehydration of the scalp.

• Controlled dryness : Dab with a soft towel instead of rubbing vigorously.

7.3. Limit the use of heat and aggressive products

• Heating appliances : hair dryers, straighteners, curling irons damage keratin and weaken the fiber⁵⁵.

• Frequent coloring and bleaching : they oxidize the fiber and increase breakage.

• Overly aggressive styling products : alcoholic gels, strong hairsprays, drying sprays.

7.4. Protective care against external aggressions

• Sun protection : The scalp is sensitive to UV rays; use an anti-UV hair spray or wear a hat in summer⁵⁶.

• Chlorinated water : Rinse hair immediately after swimming to remove chlorine.

• Hard water : Use a shower filter or cider vinegar rinse to remove deposits⁵⁷.

• Pollution : wash your hair regularly to limit the accumulation of fine particles.

7.5. Lifestyle and well-being

• Adequate sleep : 7 to 8 hours per night allows for cell regeneration and supports hair health⁵⁸.

• Physical activity : improves blood circulation and reduces stress.

• Stress management : Meditation, yoga, deep breathing, or relaxing hobbies help limit the impact of chronic stress on falling⁵⁹.

• Balanced diet : already discussed above, but it is essential to remember that hair reflects general nutritional status.

7.6. Habits to banish

• Too tight hairstyles : avoid the traction alopecia already mentioned¹⁵.

• Tobacco and alcohol : two known enemies of blood circulation and hair health¹⁹ ²⁰.

• Excessive scratching : weakens the scalp and can cause micro-lesions.

Conclusion of Section 7

Adopting a gentle care routine, protecting your hair from external aggressions, and maintaining a healthy lifestyle are simple but essential steps. These tips not only help slow hair loss but also improve the effectiveness of the medical, natural, or cosmetic solutions you choose.

👉 In the next section, we will conclude this guide by summarizing the existing solutions and highlighting why Capii represents a modern and accessible answer to hair loss.

8. Conclusion

Hair loss is a universal experience that affects both men and women. As we have seen, it can be linked to genetic, hormonal, dietary, environmental, or lifestyle factors .
