From Clare
There’s a particular kind of disappointment that comes with hair that won’t hold its shape. You wash it, blow-dry it, style it — and by midday it’s flat against your head. The volume just doesn’t stay. That’s not a styling problem. That’s a scalp problem, and it needs a shampoo that addresses the root cause rather than just inflating the surface.
This is a fundamentally different formula from our Moisturising Shampoo. Where that hydrates and nourishes, this activates. Organic chanterelle extract — the same mushroom extract that makes our Intensive Rescue Hair Mask so effective — is the fourth ingredient in this formula, an unusually high concentration for a botanical active. Caffeine stimulates microcirculation at the scalp, helping to create the conditions for stronger, fuller hair growth. Zinc PCA regulates sebum and supports a balanced scalp environment. And hydrolyzed keratin strengthens each strand from within, so the volume you create actually holds.
In my practice in Dublin and London, this is the shampoo I recommend for anyone whose primary concern is thinning or loss of volume. It works. Not overnight — but over four to six weeks of consistent use, clients consistently report hair that feels thicker, stronger, and genuinely fuller. The same gourmand rosemary and peppermint aroma as the Rosemary Strength Oil — they share the same essential oil signature because they’re designed to work together.
This is for you if
- Your hair has lost volume and falls flat despite styling
- You’ve noticed your hair feeling thinner or less dense than it used to
- You want a shampoo with active scalp-stimulating ingredients, not just gentle cleansing
- You want to support the conditions for stronger, fuller hair growth
- Your scalp feels sluggish or oily and you want to rebalance it
- You want a COSMOS-certified natural formula that genuinely performs like a professional treatment
Consider instead if
- Your hair is fine but your primary need is hydration rather than volume — our Moisturising Shampoo nourishes without the scalp-stimulating actives
- Your scalp is currently irritated or reactive — the caffeine and peppermint in this formula are stimulating by design, so start with our Sensitive Scalp Shampoo until things settle
- You colour your hair and want colour-specific protection — our Colour Saviour Shampoo is formulated to preserve colour while cleansing
- You want a special-occasion shine rather than everyday volume — our Glass Effect Shampoo delivers editorial gloss
What’s Inside
Active scalp science meets COSMOS-certified natural formulation. Four ingredients chosen to stimulate, strengthen, and rebalance — not just cleanse.
Chanterelle
CANTHARELLUS CIBARIUS · ORGANIC
At INCI position #4, this is one of the most concentrated botanical actives in any HHE formula. Rich in B vitamins, minerals, and amino acids that nourish the scalp at the cellular level. The HHE signature ingredient — appearing in three products across the range, always at prominent concentrations.
Caffeine
SCALP STIMULANT
The ingredient borrowed from clinical skincare. Caffeine stimulates microcirculation at the scalp, helping to ensure hair follicles receive the nutrients and oxygen they need for stronger growth. Applied topically, it works directly at the follicle level — this isn’t about your morning coffee, it’s about targeted scalp science.
Hydrolyzed Keratin
STRUCTURAL PROTEIN
The same protein your hair is naturally made from, broken down to a molecular weight that allows it to penetrate the hair shaft. Strengthens each strand from within, improving elasticity and resistance to breakage. The reason the volume this shampoo creates actually holds rather than collapsing by midday.
Zinc PCA
SCALP REGULATOR
A zinc compound that helps regulate sebum production and maintain a balanced, healthy scalp environment. Excess sebum weighs hair down and contributes to that flat, lifeless feeling. Zinc PCA addresses the cause, not the symptom — helping your scalp find its natural balance so volume comes from health, not product buildup.

Your Ritual
Wet your hair thoroughly with warm water. Apply to your palms and work into a lather, then massage into the scalp with your fingertips. This is where the formula does its work — at the scalp, not the ends. You’ll feel a subtle peppermint tingle as the rosemary and peppermint essential oils activate. That’s circulation increasing. Leave the lather on for a minute before rinsing to give the caffeine and chanterelle time to do their work.
Wash four times a week — Clare’s clinical recommendation for most hair types. On the days between washes, the Keratin Glow Mist keeps your hair looking fresh and adds lightweight protection.
Follow with the Keratin Volume Boost Conditioner on mid-lengths and ends. The conditioner continues the chanterelle and caffeine story with its own concentrated blend. Together, they form the Volume and Strength routine — a complete system designed around scalp stimulation and structural strengthening. Once a week, consider adding the Rosemary Strength Oil as a pre-shampoo treatment to intensify the scalp nourishment.
The Experience
Gourmand warmth with the freshness of peppermint and rosemary cutting through — aromatic and herbal, with vanilla and tonka bean grounding it into something rich rather than clinical. The same signature as the Rosemary Strength Oil. When used together, the aroma builds and layers. Your bathroom smells like a place where serious things happen beautifully.
Complete your Routine
This shampoo has a dedicated partner — the Keratin Volume Boost Conditioner. They share the same chanterelle and caffeine actives, the same aroma, and the same philosophy: volume through scalp health, not surface inflation.
Your Volume Pairing
Keratin Volume Boost Conditioner
The matching conditioner — same chanterelle and caffeine actives, same aroma, designed to continue the volume work on mid-lengths and ends without weighing hair down.
Intensive Rescue Hair Mask
Once a week, swap the conditioner for this intensive mask. The shampoo stimulates and strengthens, then the mask delivers the deep nourishment that supports lasting volume.
Enhance with Essentials
Rosemary Strength Oil
The pre-shampoo treatment that doubles your scalp stimulation. Same rosemary and peppermint signature. Apply before shampooing for a combined approach to supporting fuller, stronger growth.
Keratin Glow Mist
Lightweight daily protection between washes. Adds shine and holds volume without weighing hair down. The finishing step that extends the work of every wash.
Scalp Reset Scrub
A monthly deep cleanse to clear product buildup and reset the scalp. Keeps follicles clear and receptive to the actives in this shampoo.

Not sure which products are right for you?
for Clare’s personalised guidance.
Some clients use this as their permanent everyday shampoo. Others alternate — the KVB Shampoo on days when they want volume and body, the Moisturising Shampoo on days when they want softness and hydration. Both are right. The KVB stays in the rotation permanently for most clients who try it, because the difference in volume and fullness is something you don’t want to lose once you’ve experienced it.
