awesome product [SEP] i have hair down to the middle of my back i was afraid this scalp brush would tangle my hair or pull it out it does neither i love this scalp brush and so does my husband he tends to get flakiness during low humidity winter mostly and this has kept him from getting any flare ups i highly recommend this product just be careful with it in the shower because the outer part is plastic it could break if you drop it in the tub
