Do the switch out! LOL, but in all seriousness, just keep at him easy and hopefully he'll come around. Or even send him a link to this thread! Unfortunately, I don't know of any UK based hair brands otherwise I'd post it here. I will add that for me, the big turning point in figuring out a regimen was being able to battle knots and tangles. Since then, my hair is infinitely healthier and more manageable. Good luck!
