Minoxidil appears to be effective in the treatment of alopecia areata in patients with extensive disease (50-99% hair loss). Response rates in that group vary from 8-45%. Minoxidil was of little benefit in patients with alopecia totalis or alopecia universalis.

The 5% solution appears to be more effective.
