ok [SEP] i tried this on thick curly hair the results were quite decent you first wash your hair with the pre treatment shampoo to clarify the hair and remove dirt and oils at this point make sure to detangle the hair well and section it into smaller parts so that you can apply the keratin treatment the hair should be towel dried you then comb in the keratin treatment to each section of hair i recommend wearing gloves allow it time to process and then blow dry and finish with a flat iron the hair came out quite silky and smooth but it began to revert into fluffiness as the day went on adding a bit of hair oil helped to restrain the humidity for an at home kit it is decent but it is not as strong as salon treatments
