Even when I'm in a hurry, I always make sure to finish with this. When I have a bit more time, I use the combo of Mellow Cream (before my hair dries) and Bonding Oil (when it's almost dry). You can literally see the difference right away, so even if I don't use a straightener, I never skip this step! And if I do use a straightener on top of that, my hair looks incredible all day. Seriously, everyone should try it...ą·
