I’ve been using Kerotin Extensive Thickening Treatment for six months. I noticed since embracing my 50s my hair was breaking and didn’t look as thick or healthy. But I’m excited to say after using this product my hair is looking a lot healthier, with less breakage. I highly recommend this product for any ladies embracing their 50s, 60s.

Great product

I have very thin hair and the Kerotin Extensive Thickening Treatment has been great for my hair. I have new growth and it helps to give me curls when I have always had straight hair. It's an amazing product!
