Global Keratin GK Hair The Best Professional Hair 1000ml Kit Straightening, Smoothing Treatment For Silky, Smooth Natural - New Formula By GKhair

Amazing product nanoplastia elevated from the keratin hair is smooth brighter and softer great for curly, wild or Afro hair this does the trick and this package has the sulfate free shampoo and conditioner too

In all honesty say this product doesn't work. My hair was soft but still very curly and frizzy, I contacted GK, but all I got back was do the procedure again, which I did 3 times but still the same. I have no product left, a waste of money. I used to be a hairdresser so I know how to do these procedures.

I remained very pleased.

I used this on my hair. My hair condition is dry and damaged. It came out really nice and de-frizzed my natural frizzy curly hair. The instructions were straightforward and enough product for my medium length hair with some product left over. Excellent quality product and will use this again. A bit pricey but well worth it.

I almost retuned this as the No 2 the best cream seemed half empty but unfortunatley misse dthe return window. Hence I used it this week and result is great. You xan notbget salon quality at home doingbit yourself but almost simikar result. Would recommned . This is one of the best keratin treatments.

After using another product for 4 years it was discontinued by my usual suppliers and became nigh on impossible to purchase here in the UK. I did some research on formaldehyde free keratin smoothing treatments and this one was number 6 from a list of the top 15. It's very easy to apply. The instructions were easy to understand and straightforward. Wonderful results, I shall definitely buy this product again. It's unbelievably better than the original product I used. My hair feels silky and smells great!

Doesn't come close to salon treatment that doesn't cost anymore than the price of this product. Had a friend carry out the treatment and followed the instructions exactly as provided by GK. At first I thought it had worked until I washed hair for the first time only to find it was as curly as ever. Only positive is my hair is probably less wiry and a bit better condition.

Waste of money! Don’t work at all! Disappointed

Excelente Producto me encanto

Le lissage qui se pose comme une couleur ,gain de temps et donne un bon rendu et brillance

I like this pack because it contains everything you need to do a keratin treatment yourself, without having to buy other products separately. As for the keratin treatment itself, I love it because it doesn’t produce as much smoke when you straighten your hair. I recommend it.

I’ve had the keratin treatment done in hair salons, I just wanted to be able to do this from home because it is cheaper. I absolutely love this product. It’s a life changer. I left the treatment on for 60 minutes because I have thick, coarse, frizzy curly hair. Only took a little under 3 hours total for me. I’m hoping this will last me 6-9 weeks. 10/10 recommend!

I have 4b/c hair. I was hesitant to purchase, but read the review from another 4 tenured lady here and saw a review on YouTube from another. I have also had salon keratin treatments in the past. People need to understand that this is NOT A STRAIGHTENER. It’s a smoothing treatment that helps with frizz and manageability. And to that point, I am VERY happy with my results. There is no horrible smell or fumes like the salon version. It didn’t burn at all and I found it easy to use overall. My kit had all the advertised pieces. The shower cap is a little small and the gloves aren’t the best, but fortunately, I had extras of those items on hand. I had great results immediately and my hair stayed straight for 2 weeks in Texas heat and humidity until I washed it. My hair reverted after the shampooing but was much easier to handle and manipulate than before the treatment. After the first wash, I conditioned, dried, and flat ironed (only 1-2 passes this time) and it stayed straight again. I’ll see how long it lasts. So far my hair seems like it’s still healthy and non-damaged. I’ll try to update this review if there are any significant changes.
