1% selenium disulfide scalp care
Stop checking your shoulders.
ScalpRx Anti-Dandruff Shampoo is made to clear the flakes, the grease, and the itch, so you can wear black, book the barber, and forget your scalp exists. It's built on 1% selenium disulfide and the newest scalp science.
Made for flaky, oily scalps

Flakes aren't dirt. They aren't dry skin. They happen when a fungus called Malassezia grows too much on your scalp. It feeds on your scalp's oil, and your skin reacts: flakes, itch, grease.
Most shampoos only try to kill the fungus. ScalpRx Anti-Dandruff Shampoo does two jobs: it fights the fungus, and it clears away the oil the fungus eats. Hair comes out fresh, clean, and fluffy.
The approach
You can't wash dandruff off.
You have to take away what it lives on. The yeast eats scalp oil, so every wash clears out the excess oil and buildup it feeds on. And the formula itself carries nothing it can eat: no coconut, no olive, none of the "nourishing" oils most hair products are built on. Most shampoos feed the problem without knowing it. This one starves it.
- Clears the oil and buildup the fungus feeds on
- No oils in the formula for it to eat
- Aloe and hyaluronic acid keep your scalp calm and hydrated while it happens
The shampoo
One bottle. The whole job.
Anti-dandruff, scalp-soothing, and oil control in a single wash, for flaky, oily scalps. There's no second product to buy and no medicated smell.
- Built on 1% selenium disulfide, used against the dandruff fungus for decades
- Aloe and hyaluronic acid, so the deep clean leaves your scalp calm and hydrated, not dry
- Hair left fresh, clean, and light through the day
The new science
What the shelf brands haven't told you.
Dandruff science moved on in the last few years. The supermarket aisle didn't. Here's the short version:
Finding 01
What dandruff really is.
A fungus called Malassezia lives on every scalp. On some of us it grows too much. It feeds on your scalp's oil and turns it into something that irritates your skin. That's what flakes and itches. Not dirt.
Finding 02
What actually fixes it.
Selenium disulfide, our main active, fights the fungus. In recent human studies it also cleared away about half of the irritating oil on the scalp within two months. It works on the cause, not just the symptom.

adults live with this kind of dandruff. You're not unclean; about 400 million people share it.

~50%
less irritating oil on the scalp after 8 weeks of selenium disulfide washes in human studies.

The routine
Clear it. Then keep it.
Dandruff can be managed, not cured. The win is a routine you can actually keep. Here's ours:
Phase 01 · Clear
2-3 washes a week
Massage into the scalp, leave it for 5 minutes, rinse.
Phase 02 · Keep
2 washes a week
Two washes a week keep the flakes from coming back.
Key ingredients
What's in it. And what isn't.
Selenium disulfide
At 1%, the same strength the medicated aisle has used against the dandruff fungus for decades.
Hyaluronic acid
Holds moisture in the scalp and hair, so the deep clean doesn't leave them dry.
Aloe
So the deep clean stays comfortable, and your scalp settles back down after the wash.
Missing on purpose: oils
No coconut, no olive, none of the oils the fungus feeds on. Most shampoos feed the problem. This one doesn't.
Clear scalp, clear mind
When the flakes go, more goes with them.
2025 research measured what happens to people's physical, emotional, and social wellbeing when dandruff clears. It's not a small effect. Here's what it looks like in real life:
The black shirt, unchecked
The barber's chair, booked
The date, without the shoulder glance
