The itch that makes you pull your hood up. The flaking that makes you apologise for leaning forward. The exhaustion of managing something that never really goes away. My sister knows exactly what this feels like. I made Zema for her, and for everyone who knows it too.

Made by a brother who ran out of things to suggest.

Zema was founded by Remy for his sister, who lives with seborrheic dermatitis, scalp psoriasis and eczema. She spent years cycling through products that promised relief and delivered very little, shelves full of "soothing" and "calming" claims, and almost nothing genuinely made for a scalp like hers.

So we did something different. Working with a UK cosmetic chemist, we built a simple, fragrance-free serum around ingredients chosen to soothe, moisturise and support the skin barrier, formulated for scalps prone to dryness, flaking and itch, and honest about what it can and can't do.

We will never overstate what our products can do. Every ingredient is in the bottle for a reason, and we'll always tell you what that reason is.

Why we exist

Most people with these conditions have already tried everything.

What's already out there
  • Fragrance in everything

    Even products marketed at sensitive skin lean on perfume and essential oils, the last things an itchy, reactive scalp needs.

  • Made for hair, not skin

    Most scalp products are haircare first: built to make hair look and smell good, not to care for the skin underneath it.

  • Vague "natural" claims

    Beautiful branding and pleasant-sounding ingredients, with very little clarity about what's actually inside or why it's there.

  • One-size-fits-all sensitivity

    General "sensitive skin" ranges rarely consider what a flaky, itchy scalp actually feels like to live with day to day.

What we decided to do
  • Care for the skin, not just the hair

    A lightweight leave-in serum applied directly to the scalp, made to soothe, moisturise and support the skin barrier.

  • Keep the formula short and fragrance-free

    Every ingredient has a job, soothing, hydrating or supporting the skin barrier. No fragrance, no filler, nothing there for the label.

  • Be honest about what we can't do

    Zema is a cosmetic, not a medicine. We will never claim it treats or cures anything, and we'll always say so plainly.

  • Make it personal

    Zema was founded by Remy for his sister, who lives with these conditions. It's not a market opportunity. It's personal.

What Zema does

Three things we focus on. Nothing else.

Soothes and comforts

A light, cooling serum made for scalps prone to itching and flaking, formulated to help skin feel calm and settled on the days it needs it most.

Supports the skin barrier

Niacinamide and hemp seed oil help support the skin's natural barrier and keep moisture where it belongs, so skin feels less tight and dry.

Hydrates without residue

Aloe vera and panthenol draw in and hold moisture without greasiness, lightweight enough for daily use, gentle enough for sensitive skin.
