Just started using this less than week ago, and it's great! It does NOT make your hair grow faster. It strengthens your hair to reduce breakage so it just looks longer. I definitely notice less hair falling out in the morning in the shower, and my hair looks shinier and feels healthier! Follow the directions and rub it in for 2-3 minutes. Your arms will be tired, but it's worth it! And it smells great! Plus, each bottle is only $6 at Ulta!!
