I love having a CLEAN brush and comb. Wondering how to keep your hairbrushes clean and what to use? I use shampoo! Each time I finish a bottle, I simply add water into the bottle to use the LAST little bit and pour that into the bathroom sink, add warm water and soak my brush and comb about 20 minutes, swishing around a couple of times. That way I know I am cleaning them regularly and not giving them a chance for dirt and sticky hair products to build up. It works great for me--give it a try!
