How to use it

Two to four washes a week. The wait in the middle is the part people skip, and it is the part that matters.

01

Lather

Massage into wet scalp and hair until it foams properly. Work it into the scalp, not just the lengths.

02

Wait

Leave it on for two to three minutes so the active ingredients have time to do something.

03

Rinse

Rinse through thoroughly, then follow with the Trio Conditioner on the lengths.

Wash, then treat

One step

Three products' work, one bottle

Cleanses, adds volume and targets thinning in a single wash, instead of three separate products fighting for shelf space.

Main Trio Shampoo
  1. 01

    Cleanses

    A proper wash first. No sulfates, so it cleans without stripping the scalp you are trying to look after.

  2. 02

    Adds volume

    Hair that looks and feels thicker once it dries, which is the part you actually notice in the mirror.

  3. 03

    Targets thinning

    Ketoconazole, rosemary and caffeine, working on the scalp for the two minutes it is sitting there.

What is in it
KetoconazoleRosemaryCaffeine
What is not
No sulfatesNo parabens

Nothing new to remember. Same shower, same two minutes, just a shampoo that is actually working while it sits there.

Most shampoos stop at the first two rows.

What is in the bottle

Four ingredients doing the work, and a base that stays out of their way.

Ketoconazole
The active

Ketoconazole

The reason this is not an ordinary shampoo. It is what lets a wash actually address thinning rather than just cleaning around it.

Caffeine
Circulation

Caffeine

Applied to the scalp rather than drunk. It is there to keep the follicle stimulated for the few minutes the lather sits.

Rosemary
Botanical

Rosemary

The long-standing natural choice for scalp health, and the ingredient people already reach for on its own.

Pumpkin seed extract
Botanical

Pumpkin seed extract

Rounds out the blend and is why the formula does not need to lean on harsh detergents to feel like it worked.

Frequently asked questions

How often should I use it?

Two to four times a week. It is a treatment shampoo, so it is not built to replace every single wash if you wash daily.

Do I really have to leave it on for two to three minutes?

Yes. A normal shampoo works while you rinse. This one needs contact time on the scalp, and skipping it is the single most common reason people see nothing.

Is it colour safe?

There are no sulfates or parabens in it, and those are what usually strip colour, so it is gentler on colour-treated hair than a standard wash.

Can I use it with the Elixir Blend or Minoxidil Blend?

Yes, and most people do. Wash and dry first, then apply your serum to a clean scalp.

Will it dry my hair out?

It should not, but ketoconazole shampoos can feel drying on the lengths. Follow with the Trio Conditioner from mid-length down.
