Best japanese hair relaxers?

I have very course thick hair with a lot of volume. I am trying to get rid of the volume and have been told japanese hair relaxers work best for this. Can someone tell me which one would best without a lot of damage to the hair and where I could purchase the relaxer? Thank YouBest japanese hair relaxers?
i would NOT recommend a Japanese relaxer if you have thick coarse hair, because no matter what it would damage your hair. i wouldn't get a relaxer, a texturizer is much better for your hair but if you really want one i would say go to the salon, and get a relaxer that is made for your type of hair, wrap you hair every single night and cover it with a du-rag or a silk scarf, make sure you always moisturize your hair, and keep your dead ends trimmed, and keep your hair clean and washed weekly, invest in a ceramic flat iron, and your hair will be fabulous.
