If you want to tint your brows, this is when you'd do it. I like using the Julienne Eyelash and Brow Tint (£5) that I found on Amazon. Again, here's another instance where you want to do a patch test to make sure the ingredients in the formula don't irritate your skin.
After cleaning away all of the residue left on my brows from the lamination process, I then followed the tint instructions in the kit, leaving the dye on for 15 minutes.
When I was done tinting, I applied the nourishing solution that comes with the perm kit. This is a step you need to do whether you choose to tint your brows or not as the perm solution is quite drying, and this will help both your brow hairs and skin to stay moisturised.
