Hair loss is a normal phenomenon, men and women lose their hair daily, and it has nothing to be alarmed because the hair, like all cells in our body is alive, follows a life cycle called the cycle hair consists of three phases: antigen, cartages and tillage. In short, the hair is born and lives and dies, but try to understand in more detail why we lost our hair.
A hair is divided into two parts: the hair shaft, the visible, and its root in the scalp. Its average growth is between 1 and 1.5 cm per month, and the cutting off his hair more often will not make them grow faster, contrary to what some people think.
Life of the hair is divided into three parts:
The antigen or growth phase, is the longest it lasts between 2 to 4 years for men and up to 6 years for women. Most of our hairs, about 85% are in this phase. The hair, or rather its hair shaft, where it is in this phase, grows steadily.
The phase of involution or is it the shortest phase of the cycle of a hair as it lasts 2 to 3 weeks. It’s a transition that affects 1% of the hair on average, during which the hair no longer grows.
Lastly, the phase of "death" of hair is a period during which the hair will be eliminated. This period lasts from 2 to 6 months, affecting about 14% of hair on our head. The hair, death, is replaced by a new hair removed in the phase.
Your hair counts of 70 000-150 000 hairs, 25-30 to experience hair growth cycle of this kind throughout your life. Do not worry if you lose your hair, and find daily until a hundred dead hair on your pillow or your hairbrush. You will, despite the hair loss, hair provided for most of your life. However, the duration of hair growth cycle may vary for unknown reasons and be shorter. Metric potential will be exhausted earlier than expected and the hair will become finer, giving way to a phenomenon called alopecia.
To measure alopecia, there are two scales that of "Norwood-Hamilton" used in men and that of Ludwig women. These measurement scales used to categorize the type of baldness and accurately predict the evolution of the fall and hair loss if no action is taken to treat and eliminate. Treatments exist to improve and treat baldness, whether original or resulting from androgen deprivation (e.g. iron).
