HOW TO DO HAIR STRAIGHTENING AT HOME, WHICH BRAND IS GOOD THAT IS AVAILABLE IN TAMILNADU, INDIA?

I do not recommend something the FDA have banned in the USA.

The hair industry is a billion dollar business, they sell products that cleans & condition the hair. They also sell products that damage and causes hair loss. They also DO NOT give money back guarantee for damaged hair or hair loss due to 'abuse'. Mechanical, chemical, or thermal styling. Hair straighteners and relaxers top the hair products pose the greatest risks. Hair relaxers, related products marketed heavily to African-American women, are dangerous because they may contain powerful chemicals such as lye, a toxic substance also used in drain cleaners.

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.

Past users of the product have complained of sore throat, skin irritation, headaches, chest pain and rashes, among other symptoms. That may have something to do with the fact that the levels of formaldehyde found in the product rival those typically used in funeral embalming. That’s a lot of formaldehyde.

Reps for the company swear it’s all a misunderstanding. And the product labels itself “no formaldehyde” and “formaldehyde free.” The company has until September 12 to get its affairs in order, or risk having its product seized by the FDA. “We have been tested countless times by OSHA,” the company’s CEO Mike Brady told NPR. “And we have never exceeded a safety standard ever.” Right now, they are fighting with the FDA, but will continue to give what customers want.

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.

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

It is a billion dollar business, and they do not give money back guarantee for damaged hair or hair loss due to 'abuse', in this case, cancer.

Chemicals can enter the body through the skin.

I'm sure they havr conair products. I went to pakistan last year and they had them so I'm sure they have that brand. Just split your hair into diffrent parts or layers and simply go through and straighten every lock of hair. I split my hair in layers since I have step cut and straighten each layer. Make sure you get the ends of your hair too :)

I have no idea what's available in India..sorry..but I straighten my hair all the time with a flat iron..conair wet/dry to be exact..before you flat iron just use a heat protectant spray..that is all.

I don't know, I don't live in tamilnadu, sorry but you should ask someone who lives IN India

You can tie your hair down with a scarf
