Scalp scalers are good.

My scalp gets really oily during the summer rainy season, so I’ve been using the Scalp Cleansing Scaler from Ryeo. I apply this product to my scalp before shampooing to exfoliate and remove impurities. After using it, my hair feels much fresher and the feeling of freshness lasts longer than when I just shampoo. If you need scalp care, I recommend trying a scalp scaler.
