  • IT WORKS!
Style: 100ml
I am Black with a mixture of 3C/4A hair. Some of you are trying to see how this works on black hair so here is a review for my people. IYKYK... For the record, I don't really believe in curly hair types because my hair pattern becomes more kinky when dry and is curly/coily when properly moisturized. I'm mentioning it here as a reference point for the girlies. Again, IYKYK. I like this product. I've tried plenty of things to help my super dry natural hair and NOTHING really helped. My hair continued to remain dry. I know natural hair needs moisture to cooperate & I KNOW how manageable my hair is when it's properly moistured (my first henna treatment showed me that years ago). Well the instructions were simple and straightforward. I didn't notice any bad smell like some other reviewers and I couldn't have cared less what it smelled like if it worked. It was VERY easy to use so the girlies who struggled, must be struggling in life because a relaxer at home coloring is way more complicated than this. I purchased the revlon blower dryer (Dr. Curly or tangle something) brush to assist with blow drying process which made everything SUPER easy. I also combined it with an olaplex treatment but I don't feel if affected my results at all. Truthfully, what really helped, was when I washed my hair a week later. I used the Aphoghee shampoo & moisture balancing conditioner. I didn't do another olaplex treatment, just the Aphoghee and my curls were Chris Brown Poppin! My natural hair was super manageable and my entire head was 4C for reference. I know my hair is thoroughly moisturized and behaving when I don't have to drown it in product. I can spray it with some water, a little leave in (my hair is fine so I do mean a little) and a bit of Aussie curl gel (the only gel I use because it's mositurizing and mixes well with ALL my hair products. You ladies know ecostyler doesn't mesh with everything, but the Aussie Moist gel does! The product does appear to loosen your curls a bit, but I believe it just really moisturizes the hair more than a looser curl pattern. Again, I think really moisturized hair makes a difference in your curl pattern. I only noticed my new growth because it was super frizzy and very tightly curled compared to the the keratin treated hair. I did my treatment early February and it is mid-April. I noticed about 2-2.5" of new growth and the treatment is still going strong. I'm unsure if it permanently straightens hair after repeated treatments but my next application will probably be over the untreated hair first. This is not like a relaxer/texturizer. My hair is still very curly; it truly is more just manageable than before. However, eventually, I will try to see if it straightens hair with repeated applications or it only lasts so many treatments before it reverts back to my natural hair. As long as the treated hair cooperates, I don't see an immediate needs to reapply the treatment of the pre-treated section. I apologize that this review is long, but I wanted to give as much details from my perspective because I know I didn't have much to work with from a Black woman's perspective when I was unsure about ordering this. ... show more

  • IT WORKS!
Style: 300ml
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. ... show more

  • New Bad Formula
Style: 300ml
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! ... show more

  • Tame the locks
Style: 1000ml
This product has no bad smell and zero fumes. It’s easy to use and gives a great result. Directions are clear and it can be applied at home without any help. I’ve been using it every 8-12 weeks for the past 7ish years now and it’s one of the hair products I don’t want to be without. The downside is that it doesn’t last long enough and starts to loose some effect after a couple of shampoos (use cool water and sulfate-free shampoo to last longer). The cost is also quite expensive for what it is. Still, I think it’s the best keratin product on the market for home use and it doesn’t damage my hair, so while it’s not perfect it still ranks at the top of my list. For someone like me with kinky, frizzy, unruly hair, this formula works very well. I leave it on for an hour and rinse clean before ironing/styling. ... show more
