I just opened my 2nd 90-day bottle of the Beaute caps. I'm on a/d. I bought them primarily for my hair, but the 1st thing I noticed was the improvement in my nails. When I went to get my haircut, after taking them for about 2 months, my hairdresser said my hair looked better than it had in awhile! I didn't tell her about the caps beforehand, so I was happy that she noticed! With that said, I've had health issues, some of which could cause hair loss (thyroid), & finally had normal lab values, so the improvement could have been due to that. I decided to continue taking them, at this point, partly because I'm afraid of what will happen if I stop! Dr. Dubrow said that it will take half as long to lose the benefits from taking them that it did to receive them! Now that I've written all of this, I don't know if I've helped or not, but that's my experience with them!
