In the case of treating male hair loss, make sure the hair loss was not caused by dihydrotestosterone (DHT). DHT is the primary contributing factor in male hair thinning on the top and pattern baldness. The miniaturization of hair follicles shortens the hair growth cycle and might be the result of hereditary or hormonal-related hair loss. Our HAIR GROWTH botanical line is designed to stimulate existing hair follicles that are healthy enough to produce hair, and it will only work on follicles that can produce hair. HAIR GROWTH Cayenne & Saw Palmetto Scalp Treatment is made with botanical ingredients and is not medicine. Consult your doctor for medical treatments.
