As an elderly woman, I have very thin hair. After years of slowly losing hair, I got very worried about because I did not want to wear a wig and I was concerned that I will look ridiculous with a thinner hair. I was recommended by a friend of mine to try Pro-Form Endure, so I gave it a try. Luckily, my hair got thicker, I lose less hair and surprisingly my nails became stronger and are not breaking as they were before taking the supplement!!
