How To Use:
What I love about both No.6 and No.7 is that you can use them in damp or dry hair. My personal preference is to apply to damp hair, as I find it gives my fine, damaged and colour-treated hair the best finish. Applied dry, it well help thicker, courser and frizzier hair types get a smoother finish.
In damp, towel-dried hair, I add a couple of drops of No.7 before styling. It can also be added to No.6 (these two are an excellent pair) for added softness, shine and manageability. You can also use No.6 on damp hair as a leave-in treatment, and use No.7 as a finishing oil post-styling.
As someone who's trying to grow out a bleach-induced accidental mohawk, No.7 has been an absolute lifesaver for repairing the significant damage to my hair, while reducing further breakage and strengthening my hair. I also can't complain about the shine I get from this product (something that's usually foreign to a damaged blonde).
