  • Very impressed
I’m constantly buying products for my hair and this may be the one product I’ve been searching for. With just blow drying with my Lange le volume, I got volume, smoothness and softness. Love the results

  • Great product
I do not use a hair dryer but this product works well with Kerestate shampoo and conditioner. All products have a very light scent.

  • Love it so far
Great product, a bit stiff on the price, So far enjoying the smell, the texture. So far didn’t see too much change since my hair is pretty burned from all the highlights, but still pretty good on the edges, hope it will help to restore my damaged hair

  • Good Stuff but...
This stuff seems pretty decent, but i squirts out more of the cream than the serum. (It is a dual chamber side by side so 1 push & it dispenses at the same time). I wish this wasn't a problem, as i need the serum as much if not more than the cream. Might just be that i got a defect bottle. Other than that, i've used the product 3 times and i'm good with it. Seems to help soften my thin, fragile, frizzy hair. I have to use it though in conjusction with other product to get maximum benefit. ... show more

  • Best Hair serum EVER!!
The media could not be loaded. This product has transformed my hair and is aiding in growing out the length. It smells great and feels even better. It is silky, smooth, and you can feel the effects all day. It won’t weigh your hair down and will help control frizz. I’m obsessed.
