Very good comparison to a salon Brazilian blowout. Great val

I have been doing keratin treatments at a salon for years, at about $180-$220 a session. It's been a couple years since I have had one, and I decided to give this one a try. I am overall very pleased with the results and it was definitely a lot better on my wallet.
I have included photos of before, during, immediately after, after first wash, and after one week. I did not use products, except a heat protectant before blow drying. I will update in a couple more weeks. I did color my hair about 4 days before application, and some of my dark color was pulled into a little red. I am assuming this was mostly from the clarifying shampoo. I would not color my hair until at least 2 weeks after application, and I will probably wait a little longer afterwards next time.
While you *can* apply yourself, I strongly recommend having someone help. Especially if you have long or thick hair.
The process took my husband and I SIX hours, including washing and drying. We did take some small breaks though. The fumes were absolutely horrible, pretty much the entire process. We did it outside, with masks, and still had to step away a few times. It was very strong.
Immediately afterwards, my hair did feel a little greasier than they normally did when I did treatments at a salon. I waited 5 days before washing. Afterwards, it was not greasy at all. My hair has stayed straight and smooth. I would say it took care of about 85% frizziness.
During the no wash stage, I used a shower cap when showering. I also sleep on a satin pillow, but a sleep cap would probably be even better. I do believe a good straightener makes all the difference.
