  • Works on 4C Hair
Size: 10.1 Fl Oz (Consumer Box Kit)
This product works well on natural 4c hair. I was reluctant to try it, but I'm glad I did. It works way better on my hair versus the Design Essential STS treatment. Also, it's a fraction of the cost they charge in a salon for this type of treatment which runs a couple of hundred dollars. It smells nice, didn't irritate, or burn my scalp at all. My silk press came out just as good as a salon visit. It even lasted through some sweaty gym session with a sweat band of course too. It puffed a little at the roots, but my hair did not revert back. Once it was dry I was able to wrap it with a scarf tied down to lay it back down and/or use the flat iron for a little smoothing. And best of all I can apply this in the comfort of my own home. I definitely will be using this product from now on as a staple for manageability of my hair. Glad I gave it a chance. ... show more

  • Pretty great!
Size: 10.1 Fl Oz (Consumer Box Kit)
I have wavy, frizzy hair. The humid summer days have made it go curly and frizzy within minutes despite flat ironing every single morning. I got this to try. The instructions said to apply the best, wash out, THEN dry and flat iron. Luckily I read the reviews/Q&A while waiting. I combed the product through just slightly damp hair, let it sit for an hour, then used my volumizer dryer brush to dry, then flat ironed with the product in. Then, I washed it and went to bed with sopping wet hair (I normally never ever do this because it gets curly beyond fixing). I woke up to mostly straight, smooth, silky hair! I gave it a quick blow dry and it was 100% straight and stayed that way for 3 days despite high humidity! I just washed it again, still straight! Yes, it smells, but only when my hair is wet. Not at all when dry. I have about two uses left in the bottle so if one treatment lasts for a month, I’d say it’s worth it for me at about 30 bucks a month. I’ll update in a few weeks when I see how long it lasts. ... show more

  • Thumbs Down 👎
Size: 10.1 Fl Oz (Consumer Box Kit)
I have used other blowout products and the steps for this one was different, and the results were less than I had hoped for, after the 1st wash my hair was still very wavy and frizzy like I hadn’t even done a treatment on it. And the smell after is horrible. My husband asked what happened to my hair due to the odor. For the price I paid I expected much better results ... show more

  • Great treatment, bad clarifying shampoo
Size: 10.1 Fl Oz (Consumer Box Kit)
I love the hair treatment, but I follow the alternative instructions so my hair actually stays frizz free and straight for 5 months, BUT if you dye your hair 100% stay away from the best ph+ clarifying shampoo. It will oxidize colored hair instantly. Use a different one. You're welcome.

  • My Firts DYI Keratine Treatment - IT WAS GREAT!!!
Size: 10.1 Fl Oz (Consumer Box Kit)
I've been getting the Keratine treatment for about 1 1/2 now. The last treatment did not go so well. I had so much breakage and it did not last the 6 months as it had in the past. Getting this done at the salon is so expensive and my hairstylist was not very kind to my 4B type hair. 1. The instructions are easy to follow. 2. The kit included everything I needed, minus the hairdryer, brush, and flat iron. lolz 3. the kit has one glove - girl buy a pair. 4. My hair type is the course and thick so I semi-dry my hair before applying the treatment. Then waited 60 min and blow dry and flat iron my hair. I used too much product and my hair felt stiff. So I rinsed out 80% of the product and blow dry again and flat iron. Nore: do not apply to the scalp. follow the instructions and you'll be fine. 5. My kids said it looked better then the Salon version. In the future, I'll use have the treatment. Note: my hair is shoulder length. ... show more
