Minoxidil - how long to work?

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. 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.

Effectiveness of Minoxidil

It takes at least four to six months to see any results with minoxidil 5% (Rogaine). Some doctors recommend giving it a full year before stopping use. However, minoxidil is a marginally effective vasodilator drug with no effect on the hormonal influence of hair loss—which is the main cause. So, while it will prevent further hair loss, the odds are not likely that it will regrow all your hair.

Minoxidil is very effective in maintaining hair.

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.

We have found minoxidil to be better for keeping the hair you have from falling out rather than regrowing lost hair.  That is why many people give up on minoxidil when they "don't see anything."  Keeping hair is harder to visually appreciate than growing more hair.  Your next step is an in-person consultation with an experienced hair transplant surgeon.  At your visit, you can discuss all of your medical and surgical options.  Best of luck to you.
