First of all:
I would never use Paul Mitchell again! I was a model for one of their shows and I was given shampoo samples. I tried it once, it smelled so good! I left it on my tub, and I didn't use it again. But when I went to clean my tub, I lifted up the bottle and there was a ring around the bottom of the bottle. I couldn't clean the stain, it was hard to clean. I thought, if that's what it does to my tub, then I don't want it for my hair! Shampoos are meant to clean, not stain my hair or tub.
Hair straighteners are known as hair relaxers, keratin treatments and hair-smoothing products. They work by breaking and reforming the chemical bonds in keratin, which is the main protein that gives shape to each hair.
Hair-straightening products are allowed to contain small concentrations of formaldehyde (0.2 percent). But several hair-straightening solutions have been found to contain well above the allowable limit. For example, one popular hair-straightening product that advertised itself as “formaldehyde-free” actually contained 6.8 percent to 11.8 percent formaldehyde.
Another example: Fourteen women, including two from North Texas and one from Houston, are suing Unilever, the maker of a product they claim caused permanent damage to their hair.
"It transforms frizzy, unmanageable hair into hair that's sleeker and easier to style," said the commercial for the Suave Professionals Keratin Infusion 30-Day Smoothing Kit, which is no longer being sold
When she began looking online for more information about the product, she said she found some people who said it worked, but more who said it damaged their hair.
She discovered a Facebook page devoted to angry consumers, and there are multiple postings on YouTube. I've been warning people about relaxers since 2009 and people are giving me thumbs down!
BTW: A variety of hair-straightening products used in professional salons can expose both hairdressers and their customers to formaldehyde. The results show that three professional hair-smoothing treatments labeled "formaldehyde free" can produce the cancer-causing chemical at concentrations above the occupational exposure limits set by the Occupational Safety and Health Administration. They tested four products: Coppola Keratin Complex Blonde Formula, Global Keratin Juvexin Optimized Functional Keratin, La Brasiliana Escluso Keratin Treatment with Collagen, and Brazilian Blowout Acai Professional Smoothing Solution. While ChemRisk tested four popular brands of hair straighteners, THERE ARE HUNDREDS on the market. Nov. 11-11
By contrast, beauty salon owners and stylists generally lack a scientific background and don't have a keen awareness of the danger of working with products that contain formaldehyde, experts say.
Watch: Good Hair a documentary by Chris Rock 2009 on BET or HBO. According to Tyra Banks, 80% of the black population are part of the billion dollar hair industry. Clips on youtube videos, also.
Chemicals can enter the body through the skin.
There are other ways to make hair STRAIGHTER, without the use of any of those above. Look @ hairs in the 40's, 50's, 60's, BEFORE the invention of heating tools, before John Frieda or Paul Mitchell hair products.
