I have been using my Does & Co. for about 2 weeks now and I can tell a difference in a few things already! My eyebrows are starting to grow more baby hairs(they never grow) and I have been losing way few eyelashes since starting taking this! I have also noticed my skin is staying way more hydrated than normal so has been extremely soft basically all day every day for the last two weeks! Originally bought to help aid in my hair growth but still waiting to see if it will help. My hair grows painfully slow. But hopefully about what my hair,skin and nails will be like at the end of 30 days! Fingers crossed but definitely worth the purchase! I have two cans so I’ll be using this collagen for a good while!
