Review: Worth the money - I wish I’d known about keratin treatments in the past. The process, I had a friend put the treatment in my hair to ensure each section was fully saturated and just so you know it can tangle the hair so care is needed, I rinsed out the product by myself and dried and straightened it. My hair afterwards was pretty tangly, it doesn’t normally so I hoped it was just because this product was still in my hair. I kept my hair dry for the next 5 days, anytime it got wet I dried and straightened again, I didn’t put my hair up or put it behind my ears. The result, once I washed my hair it dried super quick and straightened well and no longer felt dry or tangly. I was on holiday with humidity and my hair stayed perfect for the duration. I normally have to use all the products and it will still fuzz up but none of that. When my hair got wet and dried on its own it was still wavy but not fuzzy. When I’d straighten it the hair stayed that way. Unbelievable! I recommend this highly, I was worried from people’s reviews especially as I suffered from substantial hair loss over Covid and worried it would ruin my hair after taking that long to grow back. I needn’t be worried as it felt funny until the product was fully washed out but afterwards I had the hair of my dreams for holiday. It’s been a month and my hair has been more manageable after the gym and being caught in a few rain showers. I’ve been using a sulphate free shampoo which seems to be working to keep the keratin on the hair
Review: Not if you still want your hair - It works beautifully and gives a wonderful thickness and sheen of Asian hair, lasts the 5 months, and is fabulous in every way. There is a smell of rotten garbage that comes from hair whenever one washes it, sweats, or gets it damp--it's vile and suffocating. The reason I'll never recommend or use this product again is simple: it provokes extreme hairloss, it falls out in clumps and sheds like a stay cat. My hair is everywhere, I get tangled in it at night. I've used this product for four years, twice annually, and went from very very thick and abundant hip length hair to shoulder length strands which I'll cut again as there's so little of it left I'm disgusted by the sight. First I thought it's seasonal, then lacking vitamins, always excuses because I loved how GK transformed my hair, until it's become clear that GK made me bald. My hairline went up and receded to the point of seeing my scalp from all angles, my ponytail is the thickness of a fringe I had prior to GK, and my hair is thin thin thin and brittle and super tense like a static scourer sponge. I can't describe my regret and tears, find another product, this one emits gasses which kill hair follicles.

### ⭐⭐⭐⭐⭐ great product for afro hair
*by D***A on 22 December 2015*

Great product. I have thick Afro-Caribbean hair and although i didn't want my hair straight (just looser curls) it is great for both. So usually when i straighten my hair it holds for about a 1/2 days, now when i straighten my hair it lasts until i wash it. When i wash my hair my curls are looser with less frizz and much more manageable. It's been 2 months since i had the treatment and the effects of the treatment are still there. the only thing i would mention is that i straightened my hair with the product in (the instructions say you should was it off and then straighten) but at my hair is sooo thick i felt i needed more drastic measures. Overall i think its great and i will definitely repurchase.
