Post Treatment care.

After you have got the Japanese hair treatment done, you have to avoid washing your hair for three days, post treatment. Also you cannot pull them up in a ponytail or bun or even pin it up. Many hair stylists believe that you must not try coloring your hair after the Japanese hair straightening treatment as, after getting thermal reconditioning done, your hair grows very sensitive. While, there are another set of hair stylists who believe that coloring of hair can be done after a gap of one to two months, at least, after the Japanese hair straightening treatment as coloring changes the bonds of hair at a much milder level than hair straightening treatment does.

You need to use special hair care products that are formulated for straight hair. Your mane has to be protected from sun at all times and has to be properly moisturized, too. So, you might have to go for regular hot oil treatments and hair spa sessions to maintain the beauty of your hair.

Brazilian Hair Straightening vs Japanese Hair Straightening:

  • The results of Japanese hair reconditioning are longer lasting as compared to keratin smoothening.
  • While, Japanese hair straightening would give you poker straight hair without any kinks, whatsoever,
  • Keratin treatment coats your hair in a wrap of protein and hence smoothens it out rather than giving a pin straight look.

Side Effects of Japanese Hair Straightening Treatment:

  • If you are fond of trying new hairstyles all the time, put in a lot of thought before going for hair straightening as curling your hair after the treatment might damage your newly treated hair.
  • If you have a sensitive skin, chances are that your scalp is also sensitive and it might get irritated by the extensive use of all sorts of chemicals and intense heat resulting in hair fall.
  • So, it is better to get a trial at a small patch of hair to see how your scalp and hair react to the straightening solutions.
  • Lastly, you have to restrain from other chemical treatments like perming etc till your hair gets back to its normal texture.
