The Cause

For most guys, hair loss is driven by DHT (Dihydrotestosterone) — a hormone your body naturally converts testosterone into. The problem is that hair follicles are sensitive to DHT. Over time, it causes follicles to shrink. Hair grows back thinner. Cycles become shorter.

There are lots of ways to fight hair loss. Most are expensive, invasive, or need a prescription. One takes ten seconds a day.

What to Expect

Short and Long Term Results

Hair growth takes time. So we included ingredients that deliver immediate benefits while working behind the scenes to support long-term growth. Here’s what to expect.

Day 01

Thicker-Looking Hair.

Cosmetic thickeners swell the hair shaft to improve the appearance, texture and volume of your hair from the very first wash.

Weeks 1–4

Hair Growth, Loading.

Capixyl supports the follicle and strengthens hair at the root. Caffeine stimulates the scalp. Saw Palmetto defends against DHT. You won't see drama yet — the groundwork is being laid.

Months 2–4

Visible Improvements.

As follicles spend longer in the growth phase and scalp health improves, many guys notice gains in thickness, density and overall appearance.

Density +79% Shedding −52% New Growth +15%

Month 4 Onwards

Results Compound.

Seeing results? Keep going. Want to accelerate more advanced thinning? Upgrade to the PLUS Set or the RD1 & RD2 anti-hair-loss system.

The Hearst Institute

Ranked the #1 Thickening Shampoo.

700 testers trialed 51 different shampoos and conditioners in a blind test while researchers analyzed changes using specialist Hair Metric technology. SH1 came out on top.

GQ Grooming Awards

Three Years. Three GQ Awards.

Nobody in the industry is more trusted than GQ, which makes winning a GQ Grooming Award pretty special. Winning one three years running is something else.

The Clock

The Sooner You Start, The Better.

By the time your mates are pointing it out and you're wearing hats more often, some damage has already been done. Keeping the hair you've got now is a lot easier than trying to get it back later.

Aroma

A scent that’s only amplified by the heat of the shower. A lot of guys tell us they find it suspiciously similar to David Beckham Instinct.

Great smelling shampoo, one week into using it and my hair is feeling better already.

Verified Customer Chris C.

[product review]

I should have purchased this shampoo a long time ago. I've only been using it for a week and I've noticed a thicker appearance already! Even my colleagues have noticed.

Verified Customer Enrico D. L. S.

[product review]

I love the smells, the packaging and the quality of this shampoo. It definitely does work as I seem to have to go to the barber more often now for my haircuts. It promotes a rapid hair growth and less shedding. I’m a fan.

Hair felt fuller and thicker after just a few days.

    Does what it say

    I have been using this shampoo for around 2 years now. I took a small break and noticed a difference, so came back to using the shampoo and couldn’t be happier.
