Thanks! It took me about 2.5 hours to do the Liquid Keratin, but an hour of that time was spent trying to detangle so that I could comb the treatment through. It comes in a spraybottle so it's easy to apply the treatment. Blow-drying and flat-ironing is pretty fast, but detangling is a huge pain. I'm optimistic though... I'm washing my hair on Wednesday for the first time since doing the Liquid Keratin, so hopefully the results will be worth it!
