I am 22 years old and am balding. From my thorough research dht and pgd2 hormones are the major causes of hair loss. In order to treat hair loss one must identify the major cause. However when it comes to deactivating scalp dht the head muscles and the face muscles could greatly help instead of commercial products. Static muscle contraction of the frontallis and occipitalis muscles helps activate an enzyme called 3-alpha hydroxysteroid dehydrogenase which deactivates dht to another form which is harmless to the hair follicles.
