Oh thank the goddess, these actually WORK!
I've been a broken record about it, but my lupus and all the medication I take has caused my already fine hair to start coming out quite a bit and lose a lot of it's (already minimal) thickness and body. I took these for a straight month and I'm honestly amazed at what this did for my locks. My hair has become thicker, bouncier and fuller. Areas that seemed to be thinning quite a bit are filling out. I'm seriously impressed with what these did for my hair. I hate to seem vain, but my long red hair has been my glory crown ever since I quit being made fun of for having red hair as a kid :-) This is making my hair look better than it did when I was actually HEALTHY! Unlike other brands that I've used, I love that you only have to take one pill a day.
Besides your hair, biotins also help to strengthen nails, especially peeling and help your skin produce more collagen. I'd like to point out that my nails were down to the quick and would not grow and the photo above is after taking these for 3 weeks.
