I started using this as I had a Keratin therapy and I need to use only sodium free products. The shampoo is enriched with Keratin which restructures the hair from deep within and rejuvenats it. My hair is more manageable and I take much less time to style it. It’s noticeably softer and straighter, looking shiny and strong. It does not say that it’s for daily use but I wash my hair with it every day and it’s all good so far. I got the conditioner too and am very happy with both products.
