This is just a tip the hairstylist told me, that when you go for rebonding you should make sure you go for regular treatment. I did mine but its a bit pricey ($280). I did the japanese rebonding one and treatment for my hair. I did my hair in Sembawang Shopping Centre, Alan & Guys.
They were very nice there, they told me a lot of info also. It was a girl that did my hair so dont be intimidated when its named Alan & Guys.
At the moment, they have a promotion package where u pay $480, and you get 4 japanese treatment and 1 free rebonding + cut. I bought that, but paid $280 first. It will last for 2 years.
ps/ they have tv there to keep u entertained while they do ur hair! so cool. haha
psps/ if you dont want to go with the japanese rebonding thingy, you can go for the promotion they have now. Which is $99 for all hair length rebonding + cut.
