There is a behind the counter product called Appearx that is a large dosage of biotin and really works.

I didn't lose my hair but it suddenly stopped growing (after a bad haircut of course). Before then, I had bionic hair that amazed my hair stylist but suddenly, nothing. My nails also got brittle. What an ugly, depressing time that was.

But, the good news is it goes away eventually. Now, your meds may be playing a part in this and in that case, I guess you have to make a choice of some kind.
