I've realised that I need to start doing some sort of routine with my hair; currently I was with cheapo shampoo and conditioner from the pound shop and that's it! It's relatively thick and in good condition, but it tends to get a bit ratty round the ends as it's midway down my back. I want to start having a weekly "routine" with it. So what products do you use? There's so much stuff available I don't know where to start
