Often mainly associated with men, hair loss is in fact an incredibly common condition for both men and women. There are a number of possible causes for hair loss, although the main cause is Androgenetic Alopecia (AGA), more commonly known simply as Alopecia or pattern hair loss. AGA Is caused by increased dihytrotestosterone (DHT) levels due to hereditary factors. More common amongst Caucasian people, pattern hair loss tends to increase with age and and many as 30% of men suffer to some extent by the time they are 30. As many as half of men will be affected by the age of 50, and by the age of 70 that raises to about 80% of men. In females, approximately 13% of premenopausal women will experience some hair loss. Post menopause, the increase is dramatic, and as many as 70% of women over the age of 65 will shows signs of thinning and hair loss.
