real mystery behind hair growth

All the various procedures and techniques for hair care regimen work to some extent and are only external means. all shampoos, conditioners, masques, treatments, tips, etc. etc..have their own limitations. But for any growth in our body, be it hair , internal physiological mechanisms are extremely important. To maintain them in good health we should have a basic knowledge about the growth of hair.

Hair growth takes place in 4 phases:
·         Anagen: The anagen phase of scalp hair follicles lasts for about 2-8 years and 90% of the hair follicles in a normal human scalp remain in this active hair growth phase at any given point of time. The longer the hair stays in the anagen phase, the faster and longer it will grow. The duration of the anagen phase determines the ultimate length of the hair. During the anagen phase, a hair strand grows about 1 cm in every 28 days. The span at which the hair remains in this stage of growth is determined by genetics.
            Catagen: As soon as the anagen phase is complete, the normal process of growth in the hair follicles stops and degeneration begins. This phase allows the follicle to, renew itself. During this time, which lasts about two weeks, the hair follicle shrinks due to disintegration and the papilla detaches and "rests", cutting the hair strand off from its nourishing blood supply. Ultimately, the follicle is 1/6 its original length, causing the hair shaft to be pushed upward. While hair is not growing during this phase, the length of the terminal fibers increase when the follicle pushes them upward
            Telogen: During the telogen, or resting, phase the hair and follicle remains dormant for 1–4 months. Ten to fifteen percent of the hairs on one's head are in this phase of growth in any given time.
       Exogen:  is the last phase of all hair growth cycles. On any given day, every human being looses about 50-150 hairs due to the exogen phase. The preceding hair strand is pushed up and out by the new, growing strand. The process causes the normal hair loss known as shedding.

By taking good care of your hair, regular exercise with proper nutrition and natural hair care products you can help your hair to be in good health.

so there you go....Understand the natural cycles of hair growth and take care to maintain their structure and function without harming them.
