Have already tried both at home kits that you can get out of Boots - they're OK but they don't 'take' in the same way that my salon tint does. I read somewhere there is an ingredient that is now lacking, which would explain why the home tints that I have tried don't seem to work that well.
Any recommendations for what I can buy from Amazon (or similar) instead that actually works? My salon does a great job but it's a nightmare trying to get an appointment so I'd rather go DIY for convenience.
