First Class Charcoal Detox Dry Shampoo — Reddit Reviews
by IGK
Updated November 12, 2026
Heavy-duty charcoal dry shampoo absorbs oil and extends wash days; roots-only application.
What the community says
A heavy-duty aerosol dry shampoo for oily roots, especially fine hair needing an extra day between washes. Charcoal Powder and starches bring serious oil control, but the strong formula can leave lengths painfully dry and needs a one-minute wait.
