Hair become thick in the youth and grow thinner and thinner with age. After growing to a certain length hair stop growing and after some time fall off. Normal age of hair is more or less 4 years. If a few hairs come off during combing it doesn’t matter much but besides long hair if the small hairs are also coming off, then there must be some reason for that.
Usually, the first symptom of alopecia is dandruff. Dandruff is due to adulterated and impure food, use of soap, impure hair-oil and excessive use and rich food. It is necessary to avoid these things.
