Keratin Complex VS Japanese Hair Straightening

Over the years, hairstyles have become as fashionable as clothes. Whenever a new, outstanding hair treatment technology comes out, almost every woman gets an appointment with her stylist to try it out. Two hair treatment technologies which have become popular are Japanese and Brazilian hair straightening. What’s the difference between the two? That is exactly what we will try to discover here.

First, there’s Japanese hair straightening. Its other names are thermal reconditioning or Yuko, and the process was created by Japanese hair expert Yoko Yamashita. Japanese hair straightening was granted a patent in its home country in 1995, after which the method spread to other parts of the world.

With Japanese hair straightening, human hair is permanently straightened with chemicals. The hair is first separated into sections, then each section is ironed, rinsed and blow-dried. Depending on the hair length and thickness, Japanese hair straightening can last anywhere from one to eight hours. Once straightened, hair will not go back to its frizzy or curly form, although any new hair growth will maintain the natural texture of your hair.

But how does Japanese hair straightening differ from keratin hair straightening? Also known as Keratin Blowout, Brazilian Keratin treatment or Keratin complex treatment, this is a straightening procedure with Keratin as a primary ingredient. Keratin is a tough protein which can be found in hair, nails and skin.

Unlike Japanese hair straightening which results to stick-straight locks, Keratin hair straightening primarily prevents frizz while allowing the hair to wave, curl or become stick-straight. Also, unlike Japanese hair straightening which has permanent results, Brazilian hair straightening only lasts from three to about five months.

Another difference between the two is that with Brazilian hair straightening, the protein keratin formula is infused into freshly washed hair using heat. With Japanese hair straightening, the cuticle or the bond of hair is changed but not with Brazilian hair straightening. What happens instead is that the cuticle is smoothened out, hair damage is repaired and hair becomes stronger, more flexible and more manageable.
When deciding which among the two treatments you should undergo, it is always best to consult your stylist at AALAM The Salon in North Dallas. The appropriate straightening treatment for you is one that will best suit the thickness, texture and natural condition of your hair.
