Hair loss: causes, diagnosis and effective care methods
Introduction:
Beautiful, shiny hair is not only an ornament, but also a reflection of health and well-being. Hair loss, however, is a problem that affects many people at different stages of life, both men and women. Not only does it affect their physical appearance, but it can also be an alarm signal indicating possible health problems. In this article, we will take a deep dive into understanding the causes of hair loss, discuss effective methods of diagnosis, and present proven hair care methods that can help restore health and luster to our hair. If you want to understand why your hair falls out and how to effectively counteract it, you're in the right place. We invite you to deepen your knowledge of hair loss and discover the secrets of healthy and beautiful hair.
The hair growth cycle
The hair growth cycle is a fascinating biological process that consists of several stages, each with an important role in maintaining hair health. It's a complex phenomenon that is worth learning about in order to better understand how to care for hair and identify potential problems. Below is a brief description of the different phases of the hair growth cycle:
Anagen phase (active growth phase):
Accounts for about 80-85% of all hair follicles. Lasts from 2 to 8 years, during which time the hair is actively growing. It is a period of intense growth that determines the length of the hair.
Catagen phase (transition phase):
This is a short transitional period during which the hair stops growing. The follicle separates itself from the blood supply in preparation for the next phase.
Telogen phase (resting phase):
About 10-15% of hair is in this phase. The hair is supported only in the follicle. The phase lasts about 3 months, after which the hair falls off, giving way to new hair.
Exogenous phase:
The hair strand detaches from the follicle and falls off. The new hair strand enters the anagen phase, starting a new growth cycle.
This cycle is a dynamic process that occurs continuously, which maintains the density of hair on the scalp. It is normal for 50 to 100 strands of hair to fall out per day, as new hair replaces the hair that naturally falls out. Understanding this cycle gives you a better idea of the dynamics of healthy hair growth and potential problems, such as excessive hair loss or thinning hair.
The most important causes of hair loss
Hair loss is a complex problem, and its causes can be varied. Here are the most important factors that often contribute to hair loss:
Genetic inheritance (Androgenetic alopecia):
Genes play a key role in the predisposition to hair loss. Androgenetic alopecia, also known as genetic alopecia, can occur in both men and women.
Hormonal changes:
Hormonal fluctuations, such as those associated with menopause, pregnancy, or polycystic ovary syndrome, can lead to hair loss.
Telogen alopecia:
Premature hair loss in the telogen phase, often associated with factors such as childbirth, stress, illness, medications, nutritional deficiencies, or hormonal changes.
Alopecia Areata:
Autoimmune attacks on hair follicles, leading to hair loss in specific areas of the scalp.
Age:
Aging affects the condition of the hair. Hair follicles gradually stop producing new hair intensively.
Stress:
Acute or chronic stress can negatively affect the hair growth cycle, leading to hair loss. Mental stress is a common cause.
Thermal and mechanical aggression:
Excessive use of hair dryers, straighteners, curling irons, and wearing hair in tight styles can lead to hair damage and hair loss.
Skin diseases and infections:
Scalp diseases, such as psoriasis or parasitic infections, can affect hair health.
Inadequate diet and nutritional deficiencies:
Nutritional deficiencies, such as iron, biotin, or zinc, can negatively affect hair health.
Medications and medical therapies:
Side effects of some medications, such as antidepressants, antiepileptic drugs or chemotherapy, can lead to hair loss.
It is worth noting that often many factors can act simultaneously, making diagnosis and effective treatment require a holistic approach. If the hair loss problem is persistent or worsening, it is always advisable to consult a dermatologist or hair specialist.
Hair loss care
Care and strengthening of hair loss requires a careful approach and the use of effective methods. Here are some practical tips that can help maintain healthy hair:
A balanced diet:
Providing your body with the right nutrients, such as vitamins A, E, C, biotin, iron, and zinc, is beneficial to hair health. You'll find them in vegetables, fruits, nuts, seeds and whole grain products.
Regular washing and the right products:
Keeping your scalp clean is key. Choose mild shampoos without harmful substances such as sulfates, and adjust the frequency of washing according to your hair's needs.
Avoiding hot styling tools
Reducing the use of blow dryers, straighteners, curling irons or other hot styling tools minimizes the risk of hair damage. If it is necessary to blow-dry your hair, use low heat and keep the dryer at a safe distance from your hair.
Pinning hair overnight:
Avoid rubbing against your pillow while you sleep by wrapping your hair in a soft material, such as satin, to help minimize damage.
Natural oils:
Oils such as argan oil, jojoba oil or coconut oil can be used as masks or additives to daily hair care, providing nutrients.
Regular combing:
Gently combing the hair daily can help maintain a healthy scalp and improve blood circulation.
Regular dermatological examination:
If you are experiencing hair loss, especially if it is a persistent problem, it is advisable to consult a dermatologist who can identify the causes and suggest appropriate treatment.
Dietary supplements for hair loss
Dietary supplements can be an effective support for hair care and hair loss prevention. Keep in mind, however, that it is always advisable to consult a doctor before starting supplements to ensure that the supplement you choose is safe and appropriate for your condition. Here are some ingredients that are often included in hair loss supplements:
Biotin (Vitamin B7):
Biotin is crucial for maintaining healthy hair, skin and nails. It affects the synthesis of keratin, the protein that makes up hair.
Collagen:
Collagen is an important building block of hair, skin and nails. Supplementation with collagen can help strengthen hair structure.
Iron:
Iron deficiency can lead to weakened hair and increased hair loss. Iron supplementation can help restore balance.
Zinc:
Zinc plays a role in cell division, including hair cells. Deficiencies can contribute to hair loss.
B vitamins:
B vitamins, such as B1, B2, B6 and B12, are important for hair health. They affect cell metabolism and red blood cell production.
Vitamin D:
Vitamin D is associated with many bodily functions, including maintaining healthy skin and hair.
N-amino acids (N-acetylcysteine):
N-acetylcysteine is an amino acid that can support the production of keratin, the main component of hair.
Other plant ingredients:
Ingredients such as pumpkin seed extract, nettle, and field horsetail are sometimes used for their potential hair health benefits. Omega-3 fatty acids are beneficial for skin and hair health. Fish oils containing EPA and DHA can support hair health.
Conclusion:
Hair loss is a problem that requires a comprehensive approach. Dermatological diagnosis is key, and changing hair care habits, using the right products and supplementation can bring the desired results. In the case of excessive hair loss, it is always advisable to consult a doctor.
