Hair grows in three different cycles: anagen, catagen, and telogen. About 90% of the hair on the head is in the anagen (growth phase) which lasts anywhere from 2-8 years. The catagen (transition phase) typically lasts 2-3 weeks, during which the hair follicle shrinks. During the telogen cycle, which lasts around 2-4 months, the hair rests.
The best way to think of the way hair grows is to picture a garden. How well it grows is completely a result of what is happening “underground”.
“Like a garden, a normal hair cycle should lead to a product, which is the hair,” says Wendy Roberts, MD, a dermatologist at a private practice in Rancho Mirage, CA. “Growth cycles are important because when they go awry, that is one of the reasons we have hair loss”.
It’s important to remember that vitamin levels and dietary behavior/patterns can be what makes or breaks your hair!
A lack of the right nutrients – including vitamins A, C, D and E, zinc, B vitamins, iron, biotin, protein and essential fatty acids – may slow down hair growth or even cause hair loss. However, correcting a deficiency in any of these nutrients may treat hair loss and promote the rate of hair growth!
Unfortunately, there is no way to reverse thinning and or balding. However, there are ways from preventing further causes that can also help speed up the hair growth process!
