How To Speed Up The Regrowth Of Hair?

My daughter has been on Loestrin 24 for 2months and her hair is falling out! I did a lot of research just now and am mortified of what I have read. This will be her last day of the pill!! My question is...will her hair grow back? Is there anything I can do to speed up the process? We are both mortified and she cries all the time. Im very concerned about her mental state.
