As someone with very fine hair (and not a lot of it), I've tried every extension variety to make it appear fuller throughout the years.  Being on TV, it's important for me to be able to enhance what I have.  From tape-in to clip-in and bonded extensions, I've tried them all, but while I love the way they look, they're really just temporary bandaids for a bigger problem.  I've taken different types of skin, hair and nail supplements since I was young, but always remained skeptical of their efficacy until now thanks to science.
