Reader experience:
"I love the way it made my hair smooth/sleek without using a flat iron," says TotalBeauty.com reader Angie who has hair that's not "that frizzy or curly." She said the treatment didn't have a bad smell, but that "my eyes did burn a little while it was sitting on my hair before [the stylist] dried it."
The main thing that did bother her, "I couldn't stand waiting 72 hours to wash my hair ... [The treatment] was supposed to last three to six months. Mine lasted a little over a month that I could tell." She blames this on washing her hair a day early and that she "didn't use the right shampoo/conditioner afterwards." She also washes her hair daily, which many stylists say will cut the effects of the treatment short.

Reader experience:
"The treatment is life-changing," says TotalBeauty.com reader Anna who has naturally thick, coarse hair that gets frizzy, especially in the back. "I have long hair too so my styling routine takes me a good hour and 15 minutes for blow dry and straightening. I was getting tired of my hair maintenance routine but I didn't want to do a treatment that would be harsh on my hair, adding more damage in the long run," she says. "I can wash and go without using a dryer OR straight iron!!!" The best part, "It's been about two months now and I haven't had to use a blow dryer or flat iron since. I highly recommend it for anyone with hair like me. You'll absolutely love it!"

I love the results, it saves me so much time every day not having to straighten my hair," she says. The treatment didn't irritate her scalp or make her eyes water, and "the [results] haven't worn off yet, and I am hoping they won't for a very long time," she says.

Reader experience:
TotalBeauty.com reader Carly, who has color-treated hair, did this keratin treatment for the first time "three years ago" because her hair is "very curly and frizzy." The treatment took about an hour and a half and "there was NO smell at all," she says. In addition she had no scalp irritation. She saw a "huge change" in her hair. Claiming it looked "smooth, shiny" and was "easy." She "would never live without it" and does it "religiously." The treatment lasts "about three to four months for me." She does claim you may "have less volume for the first few weeks after the treatment" but "after that, volume completely returns."
Keratin treatments for straight, smooth hair has reached major popularity among our readers. According to Eric Rosado, Artistic Director at Ted Gibson Salon in New York City, keratin treatments are truly, "the best option for defrizzing and smoothing many textures of hair from curly to relaxed."
Mauricio Ribeiro, creator of the Brazilian Blowout, says that since their launch, keratin treatments have evolved so much — and customers no longer complain about a strong chemical smell. That said, the process won't work without chemicals.
"To get shiny, straight hair for months, formaldehyde or other aldehydes must be used," explains Chemist Doug Schoon, president of School Scientific in Dana Point, California. "I believe [clients] have no risk" of being harmed by the treatments, he added.
