From Clare
The biggest mistake people make with volume-focused hair care is using a stimulating shampoo and then following it with a conditioner that weighs everything back down. This conditioner is designed specifically to avoid that. It continues the work the KVB Shampoo started — not by repeating it, but by completing it.
Organic chanterelle extract is the second ingredient in this formula — an even higher concentration than in the shampoo. Organic nettle leaf extract, a traditional hair-strengthening botanical rich in silica and iron, is at position eight. Caffeine continues the microcirculation support from the shampoo into the conditioning step. But the key difference is what this conditioner adds: organic coconut oil, organic avocado oil, and organic sweet almond oil nourish the mid-lengths and ends that the shampoo’s scalp focus doesn’t reach. The result is volume that holds and hair that feels nourished, not stripped.
In my practice in Dublin and London, this is always paired with the KVB Shampoo. The two formulas share the same active signature — chanterelle, caffeine, rosemary, peppermint — but each addresses a different part of the hair. The shampoo works at the scalp. The conditioner works on the lengths. Together, they’re the strongest duo in the range.
This is for you if
- You use the Keratin Volume Boost Shampoo and want the dedicated partner that continues its work
- Your hair needs conditioned ends without losing the volume your shampoo creates
- You want a conditioner with active botanical ingredients, not just smoothing agents
- Your hair feels thin or flat and you want nourishment that supports fullness rather than weighing it down
- You want to maintain the scalp stimulation from the shampoo through both steps
- You want a COSMOS-certified conditioner with genuinely active concentrations of botanical extracts
Consider instead if
- Your primary need is daily hydration rather than volume — our Moisturising Conditioner delivers deep moisture without the stimulating actives
- Your hair needs intensive weekly repair rather than daily volume support — our Intensive Rescue Hair Mask provides the deep nourishment this conditioner isn’t designed to replace
- You colour your hair and want colour-specific protection — our Colour Saviour Conditioner is formulated to preserve colour while conditioning
- You want a special-occasion gloss finish — our Glass Effect Conditioner delivers that editorial shine
What’s Inside
The same active signature as the KVB Shampoo — chanterelle, caffeine — plus the nourishing oils your mid-lengths and ends need. Designed to complete the volume story, not undo it.
Chanterelle
CANTHARELLUS CIBARIUS · ORGANIC
The second ingredient in this formula — even more concentrated than in the shampoo. Rich in B vitamins, minerals, and amino acids that nourish at the cellular level. The HHE signature ingredient, continuing its work from the first step into the second.
Nettle Leaf
URTICA DIOICA · ORGANIC
A traditional hair-strengthening botanical rich in silica, iron, and vitamins A and C. Used for centuries to support hair density and strength. At INCI position #8 in this formula, it’s present at a genuinely active concentration — not a token inclusion. The ingredient that differentiates this conditioner from its shampoo partner.
Caffeine
SCALP STIMULANT
The shared active that links the KVB duo. Stimulates microcirculation at the scalp, supporting the delivery of nutrients to hair follicles. By including it in both the shampoo and conditioner, the scalp receives a sustained dose rather than a single exposure — the science behind why this duo works as a system.
Organic Coconut Oil
COCOS NUCIFERA · ORGANIC
The ingredient that makes this a conditioner rather than a second shampoo. Coconut oil penetrates the hair fibre more effectively than most oils due to its molecular structure. Delivers deep moisture to the mid-lengths and ends — the parts of your hair the shampoo’s scalp focus doesn’t reach. Nourishes without heaviness, so your volume holds.

Your Ritual
After shampooing with the Keratin Volume Boost Shampoo, gently squeeze out excess water. Apply to mid-lengths and ends — this is where the coconut, avocado, and almond oils do their nourishing work. You can also apply a small amount to the scalp to continue the chanterelle and caffeine stimulation, but keep the focus on the lengths.
Leave for two to three minutes. The formula is designed to work quickly — the oils begin penetrating immediately and the nettle extract starts conditioning on contact. Rinse thoroughly with cool water to close the cuticle and lock in everything the conditioner has delivered.
Use every time you shampoo with the KVB Shampoo — four times a week is Clare’s recommendation. On one of those wash days, swap this conditioner for the Intensive Rescue Hair Mask for deeper weekly nourishment. The shampoo stays the same, only the second step changes.
Between washes, the Keratin Glow Mist maintains the volume and adds lightweight protection. If you’re also using the Rosemary Strength Oil as a pre-shampoo treatment, this conditioner completes the most comprehensive volume routine in the HHE range.
The Experience
The same gourmand rosemary and peppermint as its shampoo partner — aromatic and herbal with vanilla and tonka bean warmth underneath. When the two are used together, the fragrance builds and layers into something rich and grounding. The subtle peppermint tingle continues from the shampoo into the conditioning step.
Complete your Routine
This conditioner has a dedicated partner — the Keratin Volume Boost Shampoo. They share the same chanterelle and caffeine actives, the same aroma, and the same philosophy: volume through health, not inflation.

The matching shampoo — same chanterelle and caffeine actives, same aroma. Stimulates at the scalp, then this conditioner nourishes the lengths. Designed as a system.

Not sure which products are right for you?
for Clare’s personalised guidance.
Clients who use the KVB duo together consistently report fuller, stronger-feeling hair within four to six weeks. The conditioner is designed to be used with its shampoo partner every wash — this is a system, and the results come from the consistency of using both steps together. Some clients add the Moisturising Conditioner to their rotation for days when they want extra softness, but the KVB Conditioner stays as the volume anchor.
