Minoxidil takes 4-6 months before an individual should assess whether or not it helps.
Minoxidil is FDA approved for genetic hair loss – it does not help other conditions quite so much. However, minoxidil is used “off-label” for treating telogen effluvium, scarring alopecia and alopecia areata.
The main use is androgenetic alopecia in men and women (5% for men and 2% for women). It helps roughly 30 percent either maintain or achieve a slight improvement in scalp coverage. A full six months of use is recommended before deciding if it is helpful or not. Minoxidil is very effective for preventing further hair loss. You may notice some hair growth after 6 months to a year. Other options included PRP (protein rich plasma injections). These are effective when there is still hair or fuzz present in the balding area. Lastly, you may want to consider hair transplantation to fill in the balding area.
