What are the risks of a woman using men's Rogaine? (photo)

Hello there!  I am sorry for your distress.  You can absolutely use rogaine effectively as a female.  Be aware there is often an initial shed that occurs when starting any minoxidil product which is transient.  Meaning you will have an initial shed which leaves the hair ready to grow thicker and healthier.  
I will often combine minoxidil with an oral medication called spironolactone for my female patients with hair loss.  Finally, I would definitely consult with a hair specialist to make sure you are on the right treatment and to look for any reversible causes of your hair loss.

Many doctors recommend the 5% strength for men AND Women.  There are a number of treatment options, and Minoxidil (the generic name for Rogaine) is one of the least expensive ones and is considered safe.  There are several possible causes for female hair loss, so it's very important to try to identify the underlying cause.
