Idk why it took me this long to discover and buy this for my scalp. I suffer from seborrheic dermatitis and have tried almost everything. I've tried Head & Shoulders, Selsun Blue, Nizoral, pine tar shampoo, and everything else in between. None have worked to relieve scalp itch and flaky skin. This little nifty accessory worked wonders with the very first use as shown in the photo. Embarrassing, but if it can help others to tackle their seborrheic dermatitis, than so be it. My scalp feels calmer and cleaner without the use of chemicals. Thank you kitsch!
