Hair Growth :
Hair development includes the involvement of genetic, hormonal, and environmental factors; it is often divided into three distinct phases: anagen, catagen, and telogen. When in the anagen stage, hair follicles are creating new hair shafts, which have been known to grow around 1 inch each month. When in the catagen phase, hair production slows down. Hair then enters the telogen phase, where the hair follicle goes into a dormant state, and the old hair strand falls out. Every stage can be of different time lengths, but it usually takes an average of 2-7 years for one hair growth cycle. Hair growth factors vary with ages, diets, stress, diseases, and hormonal changes. Although hair growth products and treatments have made some remarkable advancements, a person should still obtain the advice of a health provider for one's unique case.
