GK HAIR Global Keratin The Best (33.8 Fl Oz/1000ml) Smoothing Keratin Hair Treatment - Professional Brazilian Complex Blowout Straightening For Silky Smooth & Frizz Free Hair

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

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.

I have very course long hair and the 100ml tube was literally only just enough. It took 4 hours ladies, from start to finish. I used half a tube at a time so I could make sure I properly rationed the cream. I left it on for an hour and fifteen minutes and the results are better than when I go to the salon. I didn’t start an inch from the scalp, as directed, the roots are the bit that needs doing the most! I applied the treatment from the very bottom of the roots and nothing bad happened. Excellent.

This is a bit pricey but it is really good and I think worth the money and I have purchased this 3 times. A little goes a long way and so when you consider this, it is not so bad and worth the treat. I am 60 years old and my hair is course, dry and wavy and this is an excellent product.

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.

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..

It’s worth it

Not worth the price at all, lasted 2 weeks

Le top!!! J'ai les cheveux épais et friser, ce produit me correspond. Pour les gens qui ont les cheveux fin attention car ça diminue beaucoup le volume. Et aussi les gens qui tiennent à leurs cheveux bouclé, ce produit lisse les cheveux et même après le shampoing ils restent raide. Mais les cheuveux sont souple, légère et brillant. Sans odeur c'est parfait. Moi j'ai utilisé inoar pendant des années mais depuis que j'ai ressayé le nouveau the best, je suis complètement tombé sous le charme de ce produit.

Very good product. Highly recommend

I was super impressed with this product. My hair responded immediately and I will buy again. Follow instructions for best results. The product arrived ahead of time and is as described.
