My hair has been very dry after had had a baby a year ago. I easily get split ends even though I use use about every two weeks. It has always been frizzy and my purple shampoo does make it more dry. I used the k18 four times. My hair has been softer and I use hair oil less frequently. I still have some frizz but my split ends are healthier!

Amazing

I started using this 4 months ago and haven’t looked back! It’s been incredible to support my hair growth, you don’t need a lot of product but make sure to warm it up before applying! It’s really healed my hair, has not fragrance and you can’t even tell it’s in your hair it doesn’t make it greasy what so ever.
