Answer

Minoxidil

  • Minoxidil appears to be effective in the treatment of extensive disease (50-99% hair loss) but is of little benefit in alopecia totalis or alopecia universalis

  • The 5% solution appears to be more effective

  • No more than 25 drops are applied twice per day regardless of the extent of the affected area

  • Initial regrowth can be seen within 12 weeks, but continued application is needed to achieve cosmetically acceptable regrowth
