Please recommend a scalp scaler that is easy to use at home.

Does anyone use a scalp scaler at home? Just like we regularly exfoliate our faces, I think it's good to get regular scalp scaling as well. When my scalp was particularly sensitive, I once received a scalp scaler treatment at a professional salon; it left me feeling refreshed, and my scalp felt cool and healthier. I tried purchasing a scaler from Ryeo to use at home, but since I had to do it myself, it was a bit inconvenient. If there is a scalp scaler product that is easy to use on your own at home, please recommend it.
