Real Results

The power of the right shampoo

Most shampoos are fragrance and foam. Ours gently removes the buildup that clogs follicles, feeds the scalp with actives it can actually use, and creates the environment hair needs to grow back thicker and stronger.

  • Cleans and unblocks the scalp pores
  • Helps block DHT directly in the scalp
  • Rich in anti-oxidants and phytonutrients
  • Packed with ingredients that boost hair growth and density

"Using the right shampoo consistently made a real difference — my scalp felt healthier within weeks and my hair started looking noticeably thicker."

Why It Works

Formulated for results, not just fragrance

Powerful active ingredients

Caffeine, oleuropein and taurine — each chosen on clinical evidence, not marketing.

Gentle, sulfate-free cleanse

Removes grease and buildup while leaving the protective oils your scalp needs.

Balances scalp pH

Apple cider vinegar keeps the scalp at a healthy pH, reducing dryness and irritation.

Rich in anti-oxidants

Protects follicles from the oxidative stress and inflammation that drive thinning.

The Ingredients

The best of the best

We only use ingredients scientifically shown to work — and we link the research.

Hairguard Caffeine Shampoo
The updated formula — 5 clinically-studied actives, zero sulfates or parabens
01

Oleuropein

Scientifically proven to support healthy hair, beating alternatives in all 4 success criteria. It penetrates deeply into the scalp giving maximum benefit without a residue.

View research →
02

Caffeine

Shown in multiple studies to both stimulate hair growth and block DHT, making it a powerful addition to any topical treatment.

View research →
03

Taurine

Shown to help slow down fibrosis (the process that reduces blood flow). It's also a proven anti-inflammatory and protects hair follicles from stress-induced hair loss.

04

Apple Cider Vinegar

Gently cleans, removing dirt, grease and plaque, but without stripping away protective oils. It also helps maintain optimal skin pH and doesn't kill beneficial bacteria like most shampoos.

5 Active Ingredients

More ingredients. More results.

Most shampoos rely on just fragrance and surfactants. Ours contains over 5 scientifically-selected actives — each one earning its place based on clinical evidence.

  • Blocks DHT at the scalp level
  • Stimulates follicle growth directly
  • Protects from inflammation
  • Maintains healthy scalp pH
  • Zero harmful sulfates or parabens
Shampoo is step one

Hair loss has three causes.
Here's the routine that hits all three.

The shampoo cleans the scalp and blocks DHT on the surface. Maxoxidil switches dormant follicles back on. The Growband fixes the root cause — the tight, low-blood-flow scalp that hair loss starts with.

Why combine them

Each product does a job the others can't

A shampoo can't reach a dormant follicle, and a topical can't loosen a tight scalp. Used together, they attack hair loss from three angles at once — which is why the customers with the fastest results run the full routine.

  • Shampoo unblocks pores and blocks DHT on the surface
  • Maxoxidil reactivates dormant follicles and thickens strands
  • Growband restores blood flow to the scalp — the root cause

Or just get the shampoo — from $33.15.

An Ounce of Prevention

Are you okay with losing all your hair in 15 years' time?

Thinning hair progresses in a well-known pattern called the Norwood Scale. The rate varies, but the typical time-frame to lose your hair is around 15 years.

Whatever stage you're at now, will you be happy in 2 or 3 years when you reach the next one? If nothing changes, your hair will get worse.

"But if you decide to do something now, then in 6 months' time you can have more, thicker, healthier and stronger hair than you have today."

Questions

Before you order

How do I use it?
Use it in place of your normal shampoo. Massage it into the scalp — not just the hair — and leave it on for a couple of minutes so the actives can absorb before rinsing. If you're using Maxoxidil, apply it to the clean, towel-dried scalp afterwards.
How long until I see results?
Hair grows on a slow cycle. Many customers say their scalp feels healthier within the first few weeks, but visible changes in thickness typically take 3–6 months of consistent use. That's why every order is covered by a 90-day money-back guarantee.
Can I use it alongside Maxoxidil, minoxidil or finasteride?
Yes. The shampoo is designed to be the cleansing step of a full routine — it clears buildup so topicals reach the scalp. Washing with it and then applying Maxoxidil to a clean scalp is exactly how the Regrowth Duo is meant to be used.
Is it sulfate-free? Will it dry my scalp out?
No sulfates, no parabens. Apple cider vinegar does the cleaning gently, removing grease and plaque without stripping the protective oils your scalp needs, and it helps keep the scalp at a healthy pH.
Is it for men and women?
Yes. It's suitable for all hair types. The mechanisms it targets — blocked pores, DHT at the scalp, inflammation and poor follicle nutrition — are the same for everyone.
How does the subscription work?
A bottle lasts about two months, so we deliver every two months and you save 15% on every order. We remind you before each renewal, and you can skip, pause or cancel anytime from your account — no minimum term, no catch.
What's the guarantee?
A 90-day money-back guarantee on all physical products. If you're not satisfied, contact us within 90 days of receiving your order for a full refund. The Growband Pro carries its own 180-day guarantee.
Which kit should I choose?
If you're early in the process or just want to try it, start with the shampoo (the 2-pack unlocks free shipping). If you're already seeing thinning and want regrowth, the Regrowth Duo adds Maxoxidil — that's the combination most customers pick. If you want to fix the root cause and get results as fast as possible, the Complete System adds the Growband Pro.

    Don’t expect a shampoo to magically regrow your hair – you need to incorporate other treatments/products etc in your routine to really notice a difference. Having said that I do feel like my scalp is a lot happier and the hairs feels more secure in my scalp, so i think it is working.

    I recently noticed that I was losing large handfuls of hair while shampooing, and my once thick hair was visibly thinning. After reading positive reviews, I decided to give this product a try—and it works! My hairdresser even pointed out that I have lots of tiny new hair growth, which was exactly what I needed to hear. I definitely give this product a thumbs up. However, I believe the trick is to leave both the shampoo and conditioner on your hair for at least 2 minutes each to get the best results.

    I was initially skeptical about whether this shampoo would deliver on its promises, but I’m pleasantly surprised—it really works! I’ve been using it for about three weeks now, and I’ve noticed significantly less hair fall. There’s much less hair coming out when I shower or brush my hair. The most noticeable change is that when I run my fingers through my hair during the day, I no longer experience the excessive shedding I used to. Now, only one or two strands fall out instead of the 20-30 strands I was losing before. I’m thrilled with the results so far and plan to keep using it. The bottle mentions that most people see major results around the 8-week mark, so I’m delighted to already see improvement at just three weeks in.

    I use this with Maxoxidil every day, dermaroller once a week and I’m seeing new growth around the temples which were previously thinning quite badly.

    Combine this shampoo and the hairguard scalp brush and you will notice a difference in how your scalp and hair feels. Mine used to be very dry and flaky, and now that’s completely cleared up. My hair feels thicker and I think the bald spot on my crown is filling in, although it’s difficult to tell for sure.
