Japanese Straightening: Chemistry of the Curl

Unlike a flat-iron or keratin treatment, Japanese straightening permanently removes hair’s curl. Find out how in this Groupon guide.

Curly hair is caused by genetics, of course, but it’s also caused by some basic chemistry. Ringlets, kinks, and waves arise when pairs of sulfur atoms in the amino acid cysteine link up together, forming, appropriately enough, disulfide bonds. (There’s a lot of cysteine in hair because it’s one of the major building blocks of keratin, the protein that makes up most of the hair shaft.) During this process, each of the sulfur atoms sheds an electron, and that’s what allows one of the most reliable techniques for straightening hair to work.

During Japanese hair straightening, a reducing agent—in this case a chemical known as thioglycolate—forces electrons back onto the sulfur atoms, reversing the process that created the bond. After the hair is nourished with shampoo and a protein-rich conditioner, the stylist will apply a solution of thioglycolate that’s activated by the heat of a dryer. A flat-iron then makes hair as straight as possible before a chemical neutralizer tells the thioglycolate to stop processing and keeps the hair in its new shape.

The process often takes three to four hours, and clients shouldn’t style or wash their hair for about three days afterward to avoid disrupting the treatment or losing that nice salon smell sooner than necessary. The chemical reaction is permanent, and changes the actual structure of the hair—that’s why Japanese-straightened hair won’t curl again the way keratin-smoothed or flat-ironed hair eventually does, at least until it grows out. At that point, if you want to maintain the sleek look, you can go back to the salon to touch up the roots.

Customer Reviews

I had a great experience. She took her time and was very professional. I love the Kerrie treatment and will definitely return.

Thank you for the review, and allowing me to serve you.

Keratin treatment came out well done. Hair cut looks good but it is still not exactly how I wanted it (difficult customer). Otherwise, she did a job well done.

The service I received was impeccable. My hair looks amazing. I've received two complements just today and I only got it done yesterday. I added color to my services and it looks so natural, exactly as I asked. The salon is first rate, with your own suite! I am so happy I bought two vouchers. Louisiana humid summers are frizz city, even for people like me with wavy hair. But my hair feels so smooth yet thick that I doubt I'll need another treatment for months. Thanks for another great Groupon!
