All men and women produce male hormones such as testosterone and DHT. These have a useful role to play in both sexes but obviously occur in widely differing concentrations. It is the higher levels of androgens found in males that explains why this form of hair loss affects men more than women.





In brief, these hormones affect the hair growth cycle as follows:





1. High levels of the 5-alpha-reductase enzyme occur in some cells of the hair follicle and sebaceous glands.





2. 5-alpha-reductase converts testosterone into DHT.





3. DHT causes the terminal hairs to miniaturize.





4. This leaves short, soft, fluffy vellus hairs that provide inadequate scalp coverage.





5. The growth phases gradually become shorter until these hairs are lost for good.
