About graying of hair is not to say the loss of pigment. I myself zna people, who in 50 years, no gray hair, gray hair and some already appears in 30 years. So gray - is absolutely not a sign of aging hair.
But the fact that the hair becomes less elastic, thinner, loses its usual luster and is prone to an early hair loss - this is a sign of aging. With age, hair becomes more sparse and the hair itself - dull and thin.
Thinning hair due to their dehydration and lack of nutrients. Disturbed structure of the hair surface, thereby they lose luster. The hair cuticle over the years begins to wear out more quickly, cease to reflect the light and becomes our rough.
So do not just trichologists all in one voice say that the hair should be already seriously look after 25-28 years. And the battle should go good money from masks to serums.
About Serum: This is something that we should not feel sorry for money. In these tools, the most powerful compositions, and molecular size is so small that the active ingredients can safely pass the skin of the head. This can guarantee the majority of masks, conditioners and other means.
Put a "thumbs up" if you want more interesting materials for hair care and coloring!
