Keratin Volume
Boost Shampoo
For fine, flat hair that's ready to rise.
If your hair falls flat by lunchtime no matter what you do — if "limp" and "lifeless" describe it better than "full" — the problem usually isn't your hair. It's everything weighing it down: product buildup, oils, and heavy formulas that smother fine strands.
This volumizing shampoo for fine hair clears all of that away. It purifies strands and the scalp, then builds them back up with hydrolysed keratin for body and strength — while rosemary, caffeine, and a cool hit of peppermint leave your scalp tingling and awake. The result: hair that looks visibly fuller, feels soft and clean, and finally holds its lift.

The difference
Purify first, then volumize
Most volumizing shampoos try to coat hair with product to fake fullness — which is exactly what flattens fine hair in the first place. This one works the opposite way. It gently purifies: clearing the buildup, excess oil, and residue that drag fine strands down, so hair lifts from the root again.
Then it builds body back in. Hydrolysed keratin reinforces each strand for thickness and resilience, helping protect against breakage, while rosemary, caffeine, and peppermint invigorate the scalp with a fresh, energizing tingle. Clean, strong, and full — the way fine hair is meant to feel.
What it does
Six reasons fine hair loves it
01
Visible volume & body
By clearing what weighs hair down, it gives fine, flat hair noticeably more lift, body, and a fuller-looking finish from root to tip.
02
Deep, gentle purification
Lifts away buildup, oil, and residue without harshness, leaving hair and scalp genuinely clean and refreshed.
03
Strengthens with keratin
Hydrolysed keratin reinforces fine strands for more body and resilience, helping protect against breakage.
04
Invigorates the scalp
Rosemary, caffeine, and peppermint awaken the scalp with a fresh, energizing, cooling tingle you can actually feel.
05
Cleans without stripping
A hydrating complex with sodium PCA and glycerin keeps hair soft and comfortable, so purified never means dry or squeaky.
06
An irresistible scent
A gourmand aroma of fresh peppermint and rosemary over warm vanilla, tonka, and sandalwood — a little ritual every wash.

Loved by fine, flat hair
★★★★★
"My hair is baby-fine and goes flat within hours. This is the first shampoo that actually gives it body that lasts the day. And the cool minty feeling when I'm washing it is honestly addictive. Smells incredible too."

"I have an oily scalp that flattens my roots by the afternoon. This really cleans without drying the ends, and my hair feels thicker and looks fuller. I use it with the conditioner and the two together are brilliant."

"Great volume and the scent is gorgeous. Fair warning for anyone with a sensitive scalp: the minty tingle is strong — I love it, but my sister found it a bit much. For me it's a five, just know what you're getting."

Asked & answered
Common questions
How often can I use it?+
It's gentle enough for regular use — a few times a week, or whenever your hair feels weighed down and flat. Follow with conditioner on the mid-lengths and ends to keep hair soft and manageable.
Will a purifying shampoo dry my hair out?+
No. Although it purifies, it's balanced with a hydrating complex of sodium PCA and glycerin that keeps hair soft and comfortable. It cleans deeply without that stripped, squeaky feeling — and following with conditioner seals in moisture.
What is the cooling tingle?+
That's the organic peppermint and menthol awakening your scalp — most people find it refreshing and invigorating. If your scalp is very sensitive, the cooling sensation can feel strong, so you may prefer to start with shorter contact and see how it suits you.
Is it suitable for vegans?+
[⚠️ CONFIRM BEFORE PUBLISHING: This formula contains hydrolysed keratin, which can be either animal-derived (from wool/feathers) or plant-derived. Check with your supplier and state the honest answer here. Do not claim "vegan" unless your supplier confirms a plant-based keratin.]
Does it contain fragrance?+
Yes — a beautiful gourmand aroma of peppermint and rosemary over vanilla, tonka, and sandalwood, created within ECOCERT's COSMOS Natural standard. It contains naturally-occurring fragrance components (including limonene); if your skin or scalp is very sensitive, review the full ingredient list first.
Is there a matching conditioner?+
Yes — pair it with our Keratin Volume Boost Conditioner. Using the duo together gives the best results: clean, full-bodied roots from the shampoo, and soft, manageable lengths from the conditioner, without losing any volume.
