If you spend a ton of time blow-drying and flat-ironing your hair and/or have curls that you want to loosen, or if your hair has frizz or lacks shine, you're likely a good candidate.
Keratin hair treatments work on a variety of hair textures including African American hair types, and color-treated or previously chemically-treated types, according to Jordana Lorraine, stylist and keratin hair treatment technician at the Dino Clark Salon in Santa Monica, California.
Do avoid Brazilian keratin treatments if you are pregnant, have severely damaged hair from too much bleaching, bleached hair that's superfine, stick-straight hair or have slight waves you want to keep intact. Basically, if your hair can stand a 450-degree flat iron, it can handle this treatment.

Is Keratin Safe?
Keratin hair treatments are controversial because Some contain (or used to contain) formaldehyde, or more correctly, a chemical called formalin (or methylene glycol) that "when heated to 450 degrees can turn back into formaldehyde," Schoon says.
Formaldehyde is on the Department of Health and Human Services' "Reasonably Anticipated to Be Human Carcinogens" list, and has been linked to certain cancers like leukemia. But the levels of formaldehyde found in these treatments are safe, Schoon explains, especially when proper protection and ventilation are used. Over the course of a keratin treatment, clients won't be at risk, unless they have an allergy to formaldehyde or other aldehydes.

Formaldehyde-Free Keratin
Real-talk time: There's no such thing as a truly chemical-free hair-straightening treatment. For a keratin treatment to give you shiny, straighter, frizz-free hair for months, it must contain formalin or another chemical in the same family. Common "formaldehyde free" products often contain: glutaraldehyde, biformal (a.k.a. oxalaldehyde — note the "aldehyde") and ammonium thioglycolate (the same chemical used in perms).

What's the Best Keratin Treatment for Me?
It's best to consult with a stylist (most offer this free of charge) because the keratin treatments "offer similar but slightly different results," says Lorraine who works with three different brands. Depending on your hair texture, the result you want and your lifestyle, some may be better suited for you.

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.
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.
