Great Supplement

I have been using this Keratin supplement for some time now at a daily dosage. It has been very helpful! I have noticed a strengthening in my nails, which tend to be very fragile. Previously, they would crack, tear, and peel constantly, never getting longer than the end of my finger. Now, I have less of a problem maintaining their length and have noticed less peeling. I have also noticed hair growth at my temples. At first, I was afraid that I was frying my hair with my styling products, however, my hairdresser took a look and noted that it was new growth! While still short in length, it is definitely still growing.
