AMAZING!!!
I followed the instruction and washed my hair with the Anti-residue Shampoo twice, let me tell you my hair was super smooth, straight, silky and soft after the treatment. I was shocked to see it made my hair shiny and straight and it truly does NOT contain Formaldehyde in any sort. I also noticed my hair ends improved, can't wait to see how long it will hold up and if will keep on repairing my hair ends.
**FREE tip, keep the Repair Mask (Step 3) for at least 30 minutes or longer**
