Can I use this mask on my scalp, and how would that work?

Yes, the product information lists the scalp as one of the intended areas of use. Clay masks for the scalp are commonly chosen when roots become greasy quickly or when buildup from styling products makes hair feel heavy and flat. The black clay and activated charcoal work together to absorb this excess oil and residue directly at the roots.

To use it, mix the powder with water to create a thin, liquid-consistency paste. Using an applicator bottle or your fingers, part your hair and apply the mixture directly to the scalp, section by section. Massage it gently in, then leave it on for about 10-15 minutes. Avoid letting it dry completely into a hard crust. Rinse thoroughly with lukewarm water, which may require a bit more effort than rinsing your face, followed by your regular shampoo. This can leave your scalp feeling fresher and your roots with more volume. It is not a substitute for a dermatological treatment for conditions like persistent dandruff or scalp inflammation.
