permanent hair straightening system

Updated on December 19, 2015

Straight hair

My hair is very unruly and thick. Curly and very frizzy especially when clean. I've tried everything, from mousses, sprays, hair straighteners to professional straightening systems. Using hair staighteners almost every day ruined my hair and took a lot of my time. I tried several professional straightening systems over the years and the two best one are the Yuko Japanese system and the Brazilian blowdry.


The yuko system is quite expensive and quite a lenghtly process. It will permanently straighten your hair and repair it in the process. No more frizz just straight healthy looking hair with a lovely natural shine. Although the treatment is permanent you will have to touch up the roots every 6 to 12 months depending how quick your hair grows and on the length.

This is my favorite treatment out of the two.

How it works

The yuko system uses ammonium thioglycolate to weaken the bonds in the hair. The first lotion used is ammonium thioglycolate based. After the application of this lotion the hair is washed, dried and straightend with a gold plated straighteners. This straightening process takes at least a couple of hours as the hair is divided in tiny sections. The bonds in the hair have now been rearranged to "straight" but they are still not "fixed".

The second lotion fixes the bonds which are now set straight. The lotion is then rinsed, the hair blow dry and the straighteners are quickly passed through the hair a second time.

All together the treatment takes about 4 hours but depends on hair type, thickness and length.

After the treatment the hair cannot be washed, styled, put in ponytails etc for two days.

Brazilian Blowdry

Unlike the Yuko, this treatment uses Keratin. It is less expensive and quicker than the Yuko but will last between 4 and 6 months.

Hair is washed with a sodium and sulphate free shampoo and dried. Then the keratin cream is applied and left to work for about 30 minutes. The treatment is then dried into the hair. Afterwards the hair is straightened with special keratin hair straighteners which are exptremelly hot.

After the treatment only shampoos and conditioners which are sodium and sulphate free can be used.

After the treatment the hair cannot be washed, styled, put in ponytails etc for 4 days.

Which one do you prefer?

Yuko or Brazilian?

Straightening irons

I just don't have the time to straighten my hair everyday, but if you do hair straighteners are a great solution. I don't think it is necessary a lot cheaper because as well as the cost of the irons you have to consider the electricity cost and all the product to protect and moisturize your hair before, during and after use.....and of course time.....

Your comments welcome!!!

      I have very curly, unruly hair and have often considered permanently straightening my hair. Using a hair straightener takes forever, so I usually wear my hair tied back. Thanks for the tips!

      Very interesting lens. My friend dislikes her unruly hair too. I'll pass on your information. Thanks.
