I have gray hair! This may not sound like the kind of report one would love to give about their hair growth. In my case, I have had the slightest of gray temples for 10 years. The hair was always short and never grew in. Over the past 2 months while using this product, I have gone from stray hairs to silver stripes. I now have 3-4 inches of gray hair growing in. I have also seen more growth at the hair line.
