Hi All,
Hair growth cycles
It takes a long period of two to six years for every hair strand on the scalp to attain its ultimate growth potential. During this lengthy growth period the hair is washed, conditioned, exposed to the heat and pollution, chemically treated etc. None of these factors affect the normal growth of the hair follicles, but they can damage the hair shaft. Hair follicles in the skin remain unaffected by the harmful effects of the environment and continue with their normal cyclical process of hair growth and renewed re-growth after resting for a small period.
