First in our series on non-scarring hair loss is the ever pervasive Pattern Hair Loss or Androgenetic Alopecia. It is mostly an inherited condition affecting up to 40% of women by menopause, and up to twice that amount in men by age 50.
Pattern Hair Loss presents differently between men and women. Women tend to have generalised thinning to the top and sides, whilst men start off with thinning at the temples eventually ending with the “horse shoe” shape that is often dreaded.
The cause of Pattern Hair Loss, though largely known, is still being determined. In men it is due to excessive sensitivity to the male hormone dihydrotesterone. In women, male hormones are not seen as a major factor, however, the exact mechanism is yet to be determined. In fact, it has been postulated that there are other non-hormonal factors which may contribute to Pattern Hair Loss in both men and women.
As it is a genetic disorder, there is no permanent cure for Pattern Hair Loss. Gene therapy, ideally the perfect treatment, has not been developed for the condition. The best that is available today is hair transplantation. In the near future, stem cell therapy will likely lead the way. For most, topical Minoxidil is the best option in addition to oral therapy with Finasteride and other anti-androgen medications are useful.
