Types of alopecia: difficulties of differentiation
General recommendations for hair loss problems
On average, 60-70% of men and 25-40% of women suffer from one or another form of hair loss on our planet. In the last century, men after the age of 40 suffered from androgenetic alopecia (baldness). Today, the number of young people aged 22-25 who are already familiar with this problem has increased.
If previously androgenetic alopecia was mainly of genetic origin, today the range of causes leading to various types of alopecia has significantly expanded due to increased radiation background, environmental problems, diseases of the hormonal system, etc.
The life cycle of hair has three main phases, and the duration of each phase is different. Anagen is a phase of hair growth and production, which is accompanied by high mitotic activity of the matrix. The duration of this phase, which has several periods of development, is genetically determined in each person and lasts from 2 to 7 years (anagen lasts 2-4 years in men, 3-7 years in women).
Anagen is followed by an intermediate phase of rest - catagen, when atrophy of the dermal papilla begins, as a result of which the cells of the bulb, deprived of nutrition, stop dividing and become keratinized.
Telogen - the phase of hair loss - lasts up to 90-100 days, and during this period the papilla begins to produce new hair (anagen IV). During this stage, hair may fall out spontaneously or be removed with light effort when combing. A new hair grows from the same follicle as the old one.
