However, the length of which reaches your hair depends on how you test them exposed. Styling, hairstyle with rigid fixation and tight, hair combing sloppy, and sometimes even a towel drying can significantly damage some strands.

Hair grows in cycles, and these cycles do not coincide. each hair growth stage differently distributed in time. So, roughly speaking, on our head grows from 90 to 150 thousand hair, each of which is either at the stage of active growth or resting phase (when the for two or three months of hair still remains in the hair follicle, but it does not grow), or falls, and all this at different times for different hair.

Each day we lose a certain amount of hair, and it is absolutely normal, because some strands simply reach the end of their life cycle. So do not panic if you find after a shower to comb tumbleweeds.

As suggested by many beauty bloggers, curly hair falls out after washing in more than direct, because their owners are usually less likely to comb his hair.

Loss of hair with age, especially in men - it is absolutely normal.

The follicles are extremely sensitive to the effects of sex hormone dihydrotestosterone (DHT), testosterone varieties. Under his influence, they are compressed, and as a result of the follicles grow shorter hair. Although usually with age in the male body produces less and less testosterone, the sensitivity of hair follicles to DHT increases. As a result, a greater number of follicles is compressed, causing eventually appear foci and baldness.

Now, when we have the clothes, and the heat in the room can control the air conditioning, hair growth is no longer necessary for us to the extent as before. But the hairs of your head are still important functions. For example, through them we get from our body's feedback about his condition. In addition, the hair protects us from the sun. Alas, all of this, we often begin to appreciate only when we lose it.
