Since 2012 we’ve been helping women (and a few men) DIY their own keratin treatments at home. Every kit comes with these instructions plus video access, so you’re never guessing.

Treatment times are estimates and will vary with the length and thickness of your hair. Every treatment can be done solo if you’ve straightened your own hair before, and if you have a lending hand it’ll be quicker.

Watch it done

Every step filmed in full, free to watch before you buy. The same page is linked in your kit’s instructions, so you can follow along or check something mid-treatment.
