The Scalp Scrubber for Seborrheic Dermatitis
Seborrheic dermatitis is chronic. Buildup makes it worse.
SD flares happen when sebum and Malassezia yeast combine with dead skin to form thick, sticky scale that medicated shampoos can't lift on their own. Your prescribed shampoo (Nizoral, Selsun, ketoconazole, ciclopirox) needs to reach the scalp to work, and scale in the way blocks it.
Scrub-Dub clears the surface so your treatment can do its job. Zinc-based antimicrobial TPE bristles work the scalp during shampoo without scratching the irritated areas. Most people use 2-3 times a week alongside their prescribed routine.
Common questions
Can I use this with my prescription shampoo, and how long until I see a difference?
Yes, that's the ideal pairing. Use Scrub-Dub during your medicated wash so the active ingredient (ketoconazole, ciclopirox, selenium sulfide) can reach the skin instead of sitting on top of the scale. Research on SD suggests meaningful reduction in flaking and itch within about 4 weeks of consistent use alongside treatment.
Should I use it during a flare, or wait until things calm down?
Both, but differently. During flares, use light pressure, work around the most inflamed lesions, and focus on the loose scale at the edges. Between flares, use it consistently to keep buildup from triggering the next one. Skipping it entirely during flares can let scale accumulate and prolong the cycle.
Can I use it on eyebrows, behind ears, or other places SD shows up?
The scalp side is sized for the scalp. The body side works on broader areas like the chest or back. For eyebrows, behind the ears, and the sides of the nose, use your fingertips with your medicated wash. Scrub-Dub isn't designed for those small surfaces.
