Ingredients that fuel
our formulas

Want to understand the ingredients list, but it's full of names you've never heard of? Here's a breakdown of our hero actives, and why each one earns its spot.

Hairdian®

FOUR PLANTS IN ONE ACTIVE, WORKING AT THE SCALP.

Hairdian®

What convinced us 

One trial, run by an outside lab, with a control group to measure against. That’s a higher bar than most plant actives clear, and it’s the whole reason Hairdian® is in here.*

Control Group

Hair fall went up

By week twelve, the thirty people on the control formula were losing about six more hairs than when they started**.

With Hairdian®

Hair fall went down

The thirty people using an essence with 2% Hairdian® were losing about seven fewer hairs by week four, about fourteen by week eight, and about twenty by week twelve**.

So what's actually in it?

one root, three leaves

Four plants: ginger root, plus thuja, red clover and mugwort leaf. It’s blended by an ingredient maker called JAKA Biotech, and the four were tested together rather than one at a time - so the result belongs to the complex, not to any single plant in it.

What it does

Most of a shampoo works on the hair you’ve already grown. Hairdian® is the part of ours that works on the scalp underneath

What people ask us about Hairdian®

What people ask us about Hairdian®

Does Hairdian® actually work?

In a twelve-week trial the group using it lost fewer hairs, and the group that wasn't lost more. That's a real result. It was also paid for by the people who make the ingredient and run on their formula rather than ours.

Is it clinically proven?

The evidence available is supplier-conducted testing, not independent clinical proof. Growth Bomb doesn't claim Hairdian® regrows hair.

Is it gentle enough for a sensitive scalp?

It was tested by the manufacturer at high volumes with no skin reaction and no eye irritation. Scalps still vary, so stop using it if yours reacts.

Why can't I find "Hairdian" on the ingredients list?

Because it goes on as its four parts: thuja leaf extract, ginger root extract, mugwort leaf extract and red clover leaf extract. Hairdian® is the name of the blend, not of a single ingredient.

THE FINER DETAILS

*JAKA Biotech (no date) Hairdian AP-GL, version 4.0, pp. 45-48. Supplier-commissioned trial, conducted by a third-party laboratory to the Test Method for Efficacy Measurement of Anti-hair Loss Cosmetic Products, in Safety and Technical Standards for Cosmetics (2015). Unpublished.

**Hairs counted by combing, measured against each participant’s own baseline. Supplier-commissioned testing of Hairdian® at 2% in the maker’s demonstration essence - not our shampoo or serum, which each contain under 1%, within the supplier’s recommended range of 0.5-5%. Participants had general hair loss; the trial included no menopausal cohort. Values are read from JAKA’s published chart, which reports the results graphically without stated figures. Individual results vary.
