Hair loss

Many types of hair loss affect men, as well as women.

Why does hair fall off?

Hair emerges from hair follicles, at around 100,000 to 150,000 on every head. The hair life cycle includes three phases:

  • The anagen phase: this is the growth phase. It lasts for 3 to 6 years. Hair grows.
  • The catagen phase: this is the resting phase. Hair stops growing. This lasts for 3 weeks.
  • The telogen phase: the falling out phase. The hair falls out and is replaced by a new hair in the anagen phase. This lasts 3 months.

Different types of hair loss

Hair loss can be occasional or chronic.

  • Occasional hair loss < than 6 months - also known as diffuse or isolated hair loss

Stress, climate changes, hormonal disruption, dietary regimens, pollution, etc. are all possible factors that could affect the hair. Hair becomes weakened, devitalized and noticeably falls out. Even though this is a transitory occurrence, it's better to react quickly at the first signs.

  • Chronic hair loss >than 6 months also known as regular hair loss

The hair follicles' activity determines hair growth. In chronic hair loss, each cycle is shorter than the previous one. After around 25 cycles, the hair follicles are worn out. They resorb and then disappear, sometimes years in advance.
The cause for this type of hair loss is mainly genetic. It is important to adapt the treatment to stop the phenomenon and strengthen the hair. Certain diseases can also cause chronic hair loss.

Does brushing my hair aggravate the problem?
Hair brushing cannot aggravate a hair loss problem. In fact, the hair found on the brush would have fallen out naturally in any case. The hair loss phase (telogen phase) lasts for about 3 months. This means once the hair is detached from its root, it will take three months to fall off. So there are no risks of any additional hair loss if you don't brush your hair with rough movements.
How can dietary supplements help?
Dietary supplements provide nutrients that are essential to the hair's vitality, such as the vitamins and minerals necessary for its growth. Vitamin B6 for example, helps complete the synthesis of cysteine, a sulfur-based amino acid that is the main component of keratin. Other vitamins can reduce fatigue or have an antioxidant effect, like Vitamin E. Therefore, dietary supplements will help keep hair in good health.
I'm 25 years old and I'm losing my hair. Is this normal?
We lose hair on a daily basis. Hair has its own life cycle. 10 to 15% of a head of hair is estimated to be in the falling phase (telogen phase). It is therefore normal to lose a certain amount of hair every day (around 50 strands per day). More noticeable hair loss can occur without it being linked to a pathology. This hair loss can be caused by the change of seasons, childbirth, fatigue, etc. Nonetheless, when in doubt, consult a dermatologist, who will recommend a treatment adapted to your case, if necessary.
