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

Amazing! I have been doing gk hair treatments for more than 7 years now and it works great. The only thing is gk the best is less effective than the normal gk treatment because it has less chemicals and anyone can buy it but the gk treatment is inly availble for salons i guess because i used to them at the hair salon now im doing them on my own. If this product doesn’t work for you it means you didn’t use it the right way like in the salons , first wash your hair so well then dry it with a towel , then apply the product on each small section of your hair , wait 1 hour, then dry your hair with the product on it with a hair dryer so well , then start straightening your hair with straightener but you should do each small sections. Watch a video on youtube before you do it

Seriously this product works! My hair is straight, frizz free and soft. I wish I’d taken a before pic so I could post. It does burn/itch if you get it in your scalp but it’s manageable. I left it on 40 minutes. I’ve washed it since and it’s still straight! It does lighten your hair if it’s color treated so fyi. You can color your hair 2 weeks after using it or right before. I will DEFINITELY use this again.

I have been using the GK hair taming straightening system for over 15 years applied by a stylist in a salon (resistant formula) as well as performed by myself at home (the best treatment) including the deep conditioner. Please be aware the formula has changed for the worse in some way. I am not a stylist, just someone who has used this product and has seen the amazing benefits of the old version and the damaging effects of the new version. The old “resistant” and “the best” versions were great about 5-10 years ago. In the past 5 years especially, I have seen a drastic change in the product and how it reacts with my hair. Also as many reviewers have stated on both Amazon and the GK hair website, when you order “the best” treatment from either Amazon or GK Hair, the product often comes in a damaged packaged with a broken seal on the bottle and the product itself has a different texture (thicker) and is hard to get out of the bottle and the smell is subtle (all previous versions had a very strong smell) This might be due to the product seal being broken and the product has gone bad or expired. I recently ordered a bottle of the best treatment directly from the GK hair website and received a damaged open product which after application caused my hair to be so extremely dry that I have to use a expensive heavy conditioning repair mask treatment just to try to heal my hair from the GK hair treatment. Beware!

I absolutely love this product. I have 4c hair, and my hairstylist suggested getting a Keratin treatment, which she said is the only one she uses. It lasts about 3 months, but I do wash my hair every two weeks, so it could last longer.I haven't attempted to apply it myself, so I can't speak to the process, but one bottle was more than enough for me. My hairstylist suggested trying to stretch my hair washing to 4 weeks to have the Keratin last longer, and I can already tell this will last longer this time around.

The media could not be loaded. Disclaimer: I am not a hairstylist.I’ve gotten keratin treatments done in the past, but I’ve only ever done them in the salon. I’ve gotten traditional ones where you cannot wash your hair for 3 days, but I’ve also gotten ones where you can do whatever you want immediately after. I always preferred to get the ones with zero down time because I have to tie up my hair a lot for my job and I also have an oily scalp so I do like to wash my hair every 2-3 days.Background on my hair is that it is naturally straight but it’s also naturally frizzy in nature. I have thick and coarse Asian hair that’s also color treated.The problem that I’ve always had with getting keratin treatments done was always with how my hair felt immediately after. Even though I know it’s meant to help your hair, my hair ALWAYS felt terrible leaving the salon. Literally dry, crunchy, stiff, and hard to comb through because of how dry it would be. Sometimes I even noticed new split ends after the flat iron part. Always made me wonder if it was because my hair didn’t get properly coated, if the flat iron was too hot, if my hair wasn’t fully dried before flat ironing, etc. And the worst part was having to keep it that way for 3 days until I could wash my hair again. Once I could finally wash my hair, it felt fine and I could feel the benefits of getting one done. But I almost felt like my hair was getting so much heat damage during the process.I decided to try this because I saw a hairstylist using this on herself. I followed the instructions exactly as they said. The product did come with a packet of their deep conditioner, but I decided to use my own because on the back of the packet it said to leave it on for 20 mins, but on the instructions for the treatment it said to leave it on for 5 mins. I wanted to give this a fair shot so I decided to use the deep conditioner on another day since I was running low on time.I did blow dry with a round brush and tension as they said, and made sure every section was completely dry. For the flat iron part I set mine to about 375F and did 2 passes for each section.I really have to say I’m super impressed by the results. I really do hope this lasts about 3 months like a traditional keratin treatment. Once I got to the flat iron part I did notice the smell was similar to a keratin treatment but the product during application didn’t really smell like that. Best part was my hair didn’t feel dry and unmanageable afterwards like my past experiences in salons.I took one star off because the ingredients listed on the box, on the actual bottle, and on the Amazon description are different. That does make me suspicious, but it does seem to work so I’m willing to give it a chance.Also, I had to use what felt like half the bottle for my hair length and density which means I may get 2-3 uses out of the 3.4oz bottle. However, if this really does work and I only have to do this every 3-5 months, that is totally worth it!
