GK HAIR Global Keratin The Best (10.1 Fl Oz/300ml) Smoothing Keratin Hair Treatment - Professional Brazilian Complex Blowout Straightening For Silky Smooth & Frizz Free Hair

This is not a genuine product. I have been using this treatment for years and the last two purchases I have received from this seller are defective. Arrives in a sealed bag but the seal in the product bottle has been burst and the product looks to be watered down. I thought previously it was more liquid because they had changed the product but having used the last bottle with no where near the same result I now feel very disappointed and cheated, especially when it costs £144 per bottle! Not again, I am sending this one back for a refund. Will be reporting the issue to amazon and will not be purchasing from this seller again.

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.

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.

This product is excellent. Having done many treatments on clients, I find it to be great. Take note though, make sure you cleanse REALLY well beforehand, leave product on for as long as possible taking care of over-sensitised ends and MAKE SURE THE CLIENT KNOWS TO DRY THE HAIR WITH THE NOZZLE POINTING DOWN!! I had one lady come back but she was blow drying it upside down with a travel hair dryer ie NO nozzle!! Once I showed her how to do it properly, it was fine so she's purchased a decent hair dryer and can now manage it at home. I would not use any other product. I have been at the forefront of hairdressing for over 20years..

Very good product .Made my hair soft and beautiful at the firSt time . But This time my hair fall's down a bit any way it's very convenience for me .

Very pleased. I used global keratin years ago then decided to try cheaper brand ( got 1 litre for £100) and it only made my hair worse with each treatment. I just disposed it and ordered gk worrying a bit about it's quality these days. I was not disappointed. My hair is really soft and silky even tho I have done much damage to it past year. I highly recommend this product. It's definitely legitimate gk treatment.
