Having dyed my hair black, one immediate issue was apparent: my eyebrows were brown. So off I went to Boots to pick up one of these
I have never used Dylash before, but found it surprisingly easy. The instructions for use on brows is similar to those for lash dying to begin - mixing small amounts of the cream colour with the activating solution in the little plastic dish, but has a much quicker (and safer! think hydrogen peroxide near your eye ball..) application process, using a little plastic spooley. It only takes two minutes to develop, and then you wash it off.
The result: Well I was going to take a before and after shot but forgot! sorry. You can see from photos on other blog posts that my eyebrows were a medium brown, and now they are black.
This product costs £7.50 from Boots, but has up to 16 applications - each lasting for up to 45 days - so in retrospect not too expensive for what it's worth!
