Healthy looking hair is in general a sign of good health and good hair-care practices with proper nutrition being important. Hair is the fastest growing natural tissue in the human body and for optimum hair growth to take place, the metabolic requirements of the hair follicles must be satisfied. The speed of hair growth varies based upon genetics, gender, age, hormones but it may be reduced by nutrient deficiency. If your hair has been feeling dry, brittle, or thinner than usual, it may be time to introduce a new product into your hair care routine. We all need a little pick me up sometimes, and your hair is no exception.
