Our Standards

Most grooming products are 80% water and 20% things you can't pronounce. We started from scratch - pulled every ingredient that didn't earn its place, cut everything we wouldn't put on our own skin, and built the formula around what actually works. 

No parabens, no sulfates, no synthetic fragrance, no PFAS, no microplastics, no silicone. Not because it's trendy. Because it's the standard every men's grooming product should've been held to from the start.

Ingredients
  • Manuka Honey - supports scalp health, reduces dryness and irritation.
  • Olive Oil - deep moisture without the weight.
  • Apple Cider Vinegar - restores pH balance and removes buildup.
  • Coconut Oil - conditions without leaving residue.
  • Aloe Vera - calms and hydrates at the scalp.
  • Jojoba Oil - balances oil production naturally.
  • Vitamin E - strengthens and protects over time.
How to Use
  1. Wet your hair thoroughly.
  2. Squeeze a small amount into your palm - about the size of a quarter.
  3. Work it into your scalp first, then through the lengths.
  4. Rinse until the water runs completely clear.
  5. Follow with Conditioner No. 02 for the full routine.

One bottle lasts 2-3 months. You need less than you think.

WHAT'S IN IT

Every ingredient earns its place. Technical, precise, functional — and free from unnecessary and excessive chemicals.

THE ASTERISK MEANS SOMETHING

Nothing toxic. But it works.

Most men's care asks you to choose between performance and clean. We didn't. Every UNDIRTY format is made with real actives — and formulated without the list below.

  • Parabens
  • Formaldehyde
  • PFAS
  • Phthalates
  • Silicone
  • Synthetic fragrance

THE RITUAL

Four steps. Somewhere around eight minutes.

  1. 00Rinse

    Hot water, about a minute. Let the day come off you first.

  2. 01Shampoo

    Dime-size at the scalp. Two hands. Thirty seconds of actual scrubbing.

  3. 02Conditionar

    Mid-length to ends. Leave it while you wash your body. Rinse.

  4. 03Body wash

    Loofah or hands — your call. Rinse cold if you're feeling heroic.

Frequently asked questions

What's the difference between Fire & Spice and Manuka Honey?

Fire & Spice is earthy and smoky - cinnamon, cardamom, cedar. Manuka Honey is warm and mellow - honey, vanilla, bergamot and sandalwood.

Do I really need conditioner if I have short hair?

The Hair Set is designed as a system: the shampoo cleans gently, the conditioner hydrates and softens. And you need it whether your hair is short or long.

Is this good for dandruff or flaky scalp?

Our formulas are designed to moisturize and strengthen, combatting the most frequently encountered problems in men's hair care.

Should I start with the Travel Set or go straight for full size?

If you've never tried it, grab one or both Travel Sets but it doesn't last long. The full Hair + Body Set is pound-for-pound our best deal.

Is this safe for color-treated hair?

Absolutely! Sulfate-free, silicone-free, and pH 5.5 balanced. Won't strip color.

What if I don't like it?

30-day satisfaction guarantee. If it doesn't perform, we'll make it right.
