I've been telling anyone who'll listen about my love for scalp massagers. Not only do they help stimulate blood flow to the scalp, but they also seem to make my manicures last longer, thanks to the fact that I don't have to use my fingers to scrub my hair clean. At only £5, Thyes Shampoo Brush Silicon Scalp Massager (£5) is definitely worth picking up on your next Amazon order. It'll make hair-wash days much less daunting and much quicker. Promise.
