How does hair grow and fall?

Human beings have between 100,000 and 150,000 hairs, each growing 0.7 to 2 cm per day.

Both men and women have 25 cycles for their hair. That is, the hair grows and then falls out a maximum of 25 times.

Women have longer cycles, that's why they have longer hair. It is because men have more testosterone than women that their hair cycles are shorter. As a result, they lose their hair faster.

Each cycle is broken down into three phases:

- The anagen phase which is the growth phase of the hair. It lasts between 3 and 5 years. Most of your hair is in this phase.

- The catagen phase which is a resting phase where the hair stops growing. This phase lasts about 3 months.

- The telogen phase which is the phase where the hair is expelled from the scalp and falls. It takes about 3 months.

We lose every day between 30 and 60 hairs but this figure can climb up to a hundred.
