Works perfectly, cuts blow dry time by 50%
I have been using straightening products like this for about 13 years. I avoid ones with formaldehyde. I also only use express formulas as I am a daily hair washer. I followed the online instructions and let it sit under a plastic cap for 1 hour. The directions are the same as most brands. The smell burned my eyes a bit, as I was applying. Once I blew it dry and flat ironed, the fumes, surprisingly were not as bad. I waited until the next morning to wash. Scalp was a little itchy, but not too bad. I was skeptical the first week, but since it has only gotten better. These are some of the best results I've had. The bottle should be enough for four more times. 4 or 5 treatments total. I have hair just above the shoulders. I'd say this is quite the bargain. Watch lots of videos and you can easily tackle this yourself. I only paid someone once 13 years ago and have been doing my own since. My natural hair looks like it's permed with gray rods for refrence... only looks good curly when it's long.

5.0 out of 5 stars Great So Far!
Reviewed in the United States on March 2, 2017
Let's get one thing out of the way- Keratin/Brazilian treatments do NOT remove all curl/wave from hair. Their purpose is to smooth, defrizz, and relax texture. If you're looking to do those things and have some time on your hands, this is your stuff!

I began by using Ion's [[ASIN:B003XXKANI Clarifying Shampoo]], washing my hair thoroughly three times with it before gently combing out and drying with a large, round brush and high heat. This is where I saw the most damage occur to my hair (albeit very little); if you have insanely thick, always tangled hair like I do, combing without conditioner or leave-in treatment is hell. Be patient, work in small layers, and you'll get through it. I did this before bed, splitting the entire process up into two days.

The next morning, I divided my hair into front and side segments and applied the product as described; in small sections, enough to saturate, but only slightly building up on front of my fine-tooth comb with ran through each section. As others mentioned, the fumes here are awful; the product's smell itself isn't so bad, but the chemical stench sneaks up on you! make sure you're in a well-ventilated room and take breaks when you need them.

I allowed the application to sit for about 30 minutes, where it dried to a damp-tacky stage. I followed this with the medium-heat blow dry step, again using my large, round brush to dry the product completely while also removing some of my natural curl/wave. This is the half way point, so celebrate! The next step's the real pain.

I divided my now-dry hair into three sections again- back and sides- and enlisted my boyfriend to straighten the back portion, using my digital CHI at 365 degrees. You really need to get that straightener up to the roots and thoroughly over the shaft of the hair for at least 8 passes per section, so definitely enlist a friend to help you. I'm pretty good at straightening my hair by this point in my life, but the tiny sections and repeated passes would have been too much for me! Boyfriend did about 12 horizontal layers on the back segment, each divided into 4 smaller groups. I then completed each side on my own. As mentioned, you'll want to make at least 8 passes, or until the chemical no longer smokes on your hair. The entire flat ironing process probably took two hours.

Although the bottle and videos say it can be washed out next day, I left it in for 36 hours and even tied my hair back loosely at one point without issue (working out with my hair down is a HUGE no-go). when I did finally wash, I used a sulphate- and sodium-free shampoo and deep conditioner. Here's the real magic: When I got out of the shower, I noticed my waves were far more relaxed than normal. When I began blow dry my hair, I was able to use a paddle brush and only two sections of hair to get a perfectly-acceptable, frizz-free, non-poofy, straight 'do...in about 10 minutes! I finished it with a round brush to add some lift. By contrast, a typical blow-out before took 4 layerings of hair, and 45 minutes of blow-drying using a round, ceramic brush- leaving me with "straight" but puffy, frizzed out hair that needed to be finished with a flat-iron before I could leave the house. My hair is now insanely soft and shiny, as well. Bonus!

TL;DR- it's a pain to apply, takes forever, and smells bad, but you WILL have great results if you follow the instructions and invest the time.

**UPDATE 8.19.17** It's been six months since I applied this product, and it's now completely out of my hair. That said, it stayed in completely for about four months before it started to fade. My stylist was impressed; every time I went for a cut and color, she remarked that my hair was so much easier to work with and style. I'd agree!

After the product "wore off," my hair went back to its usual curl pattern; no damage or permanent changes to hair texture. Over all, I'd still rate this five stars; although the treatment didn't last as long as a professional one may have, you can't beat it for the price. Make sure you use gentle, sulfate-free shampoos and conditioners. I'll be applying it again in the fall- it's too hot and humid for a day spent with a straightener in the summer!
