Can I use this mask alongside other active scalp treatments or exfoliants?

The product information notes that if you are using several active scalp products at once, you should introduce them gradually. This is because charcoal masks, chemical exfoliants (like salicylic or glycolic acid), and medicated shampoos can each increase scalp sensitivity or dryness when combined too aggressively. A practical routine might be: use the charcoal mask once a week on a day when you are not using a leave-in scalp serum, a peeling tonic, or a prescription treatment. If you use a daily scalp tonic, apply it on non-mask days.

Watch for signs of over-processing: tightness, flaking that wasn’t there before, or increased sensitivity when touching the scalp. If any of these appear, reduce frequency of the strongest product in your rotation. Always avoid applying the mask to irritated or broken skin. If you have a diagnosed scalp condition (seborrheic dermatitis, psoriasis, eczema), consult a dermatologist before adding a purifying mask to your regimen.
