My hair is a little kinkier than before but still low-frizz and shiny. As in my previous post, my hair did'nt take the GHD heat well so the ends are quite split now. (Half-because I have'nt had a trim yet.)
I'm using the Global Keratin shampoo with Juvexin religiously and a normal sodium sulfate free conditioner. I wash 2-3 times a week so I assume it helps to prolong the treatment.
At this rate I might not need a re-treatment for another 2 months!
