Review: No good for African hair. - No change was seen after use.
Review: I have hair down past my bra clasp, a majority 3B curls with some 2A randomly mixed in and I hate it because my curls are really disorganized. I have straightened it basically every day since I was young, which is about an hour of blow drying followed up with a straightener. Huge pain in the butt time-waster. Due to a sharp increase in workload this semester, I decided I needed a more permanent solution because still I need to look professional at work. I can't look like I've just given up, people! Anyway, I researched keratin treatments (all summer ya'll, all summer) and purchased the 120 ml bottle after reading all the reviews. After doing the treatment, I shampooed with sulfate free shampoo and conditioner and decided to test it out by just letting it air dry (I've always dreamed of doing this). I AM AMAZED! My hair is silky smooth and completely straight! Zero effort required! I literally wanted to cry tears of joy. It's been a couple of weeks and it is still perfect so I have hopes that this will last for the 3 months. For anyone interested, I did not have the patience to follow all of the directions and instead did what was recommended by another reviewer (slightly modified for laziness/impatience): 1. Shampooed (X2) with my dish soap to get all the oil and product out. I didn't feel like ordering a clarifying shampoo, ain't nobody got time for that. No conditioner or products after clarifying. 2. Comb (carefully!) with wide-tooth comb. Let hair air dry. Yeah it looked crazy. 3. A few hours later I applied the treatment all over with a dye brush and combed out the excess. I've been dyeing my hair at home for years but if you don't have practice with that you may want a friend to help that you don't mind seeing you topless. Or wear a towel. Whatever. 4. Blow dry completely. Your hair is gonna feel really bad at this point. Power through. 5. Make sure it is COMPLETELY dry and then flat iron it like you've never flat-ironed before. Go to town, get the roots, make several passes, use a comb, be serious. Torture your hair because it is the LAST time you're going to have to for a very long time (yay!). 6. I think I sat around for like an hour before I finally said forget it, there's no reason to wait, I've heat sealed this stuff and my head has cooled off. Look, I have really nice sheets and I couldn't fathom sleeping with a towel on my head to protect them, ok? Stop judging me. 7. Shampooed and conditioned with sulfate free and Voila! You already read the amazing results. This product is a godsend and I will be ordering it for the rest of my life. One drawback (not the product's fault) that I hadn't thought about it that if I let it air dry, it's pretty flat. I'm not complaining because straight is what I wanted and I can still put any kind of curl in it with a curling iron. However, I have started hitting my roots with a blow dryer for some volume and it works perfectly and takes maybe 5 minutes. Then let the rest air dry. BOOM, this stuff is gold. I just threw out tons and tons of hair products and cleared off my bathroom sink. There's so much room for activities now! Glorious. **UPDATE: I did this treatment in late Aug 2017. It is now the middle of January 2018 and I am about to do another treatment because my roots have grown out quite a bit and are starting to get wavy. It lasted over 4.5 months perfectly. Highly recommend this product.

## Questions & Answers

**Q: How many applications?**
A: 1 for sure some get 2 out of it, however if your hair is super long I suggest you get the 10oz bottle, it also comes in kits

**Q: Do you have 250 ml or more big ?**
A: yes, we do have 300ml and 1000ml

**Q: 120 ml enough for long hair (til waist)?**
A: 120 ml are Not enough if your hair is long  you will need 2 , the thing is that i don’t recommend this product in the first place, poor results and does not last for even a couple of weeks, but the nightmare for me was the unbearable smell of it , i tried many at home keratin treatments but this was theWORST never again

**Q: It’s the second time asking because I didn’t get any answer, is it contains formaldehyde? And what is the percentage of formaldehyde?**
A: Yes it does and this is mentioned clearly in the product. All straightening hair products have formaldehyde or similar chemicals bcz its the only way for the product to work. Google the other chemicals to know them. One more thing it has smell not as strong as other keratin products but not as mentioned by one of review that has no smell at all just to let you know.

### ⭐⭐⭐⭐⭐ Review
*by Q***A on 14 June 2025*

This treatment worked exactly how I wanted it to and I’m very impressed with the results. I would definitely say the process is pretty challenging because the fumes released by the product itself are really strong and apparently very bad for you so I would definitely recommend doing the treatment Nearby an open window. I did it beside an open screen door in my basement. Also, don’t do it in an area that your family will be in often because it leaves a fog of smoke in the area until it is well ventilated so I did this in my basement beside my screen patio door with it open And had to step outside multiple times throughout the process and then left the screen door open overnight to let the area clear and it was fine by the morning, make sure fog doesn’t go through your whole house because it is hazardous to be in injesting for a long period of time. Before: I had tight for a 3C curls which were very pretty but very hard to manage. I’ll get compliments on my hair a lot, but I didn’t really like the state especially going into summer because it was hard to manage as I said, I would have to put a lot of product in it and wash my hair almost every day I wouldn’t be able to sleep on it or I would wake up and it would look very bad so I would have to Basically wash my hair every day to make it look good and if my hair got wet, it would frizz up a lot, especially in her humidity so I wanted to do this treatment for the summertime so I could feel comfortable wearing my hair down without having to worry about it frizzing up, especially going into pools or into the lake at my cottage and not having to straighten it or put it in braids After: the treatment left me with waves or loose curls, which is what I desired, and when I got out of the shower, it was much much less frizzy than it typically is when I get out all I had to put in was some light products. I was a bit concerned because when I brushed my hair and didn’t go into curls like it typically does. It just went straight, but as long as you scrunch in all the products that you use it leaves your hair like how the after picture is. I wore it to a festival down last night and it looked at the whole time I slept on it and I woke up and it still looks good. The photos from after I woke up. I would definitely say the straightening was pretty much the same as it normally is, but I washed out the product 12 hours after straightening I put around 7 to 10 passes on each section And blow dried it with my revlon blow dryer and so yeah, I left it in overnight and for a couple hours, so 12 hours in total and then washed it out and I really enjoyed the results. I would recommend for girls with curly hair that want it to be more manageable and just know that it won’t leave your hair permanently straight and the treatment only lasts for 3 to 4 months, which is perfect for me And it might not be ideal for you so don’t go in to the treatment expecting to leave you with permanently straight hair because that’s not what it does.
