Description

Balancing Scalp Tonic is a topical scalp-soothing elixir to instantly calm sensitive scalps, relieving dryness and flaking to improve scalp comfort.


Soothes & calms dry, flaky scalps*
Scalp feels soothed after only 1 week* – 10/10 agree

Packed with scalp-loving amino acid Sarcosine, this potent infusion helps to rebalance the scalp microbiome and reduce sebum production.


Perfect for sensitive scalps, the weightless, silky texture absorbs quickly without residue (won’t leave roots looking greasy!) – leaving the scalp feeling healthier, fresher and hydrated, with no oily roots.


*Consumer tested

Apply 3-4 pipettes of tonic directly to damp scalp on sensitive areas, then gently massage in with fingertips (or using the Scalp Massager). Do not rinse. Use 3 times a week.

Formulated with hair and scalp-loving actives plus skincare ingredients, to cleanse, moisturise and treat your hair from the roots.


Sarcosine improves overall scalp health, helping to soothe the scalp by reducing scalp discomfort. A naturally occurring amino acid, this scalp-loving active is a soothing ally for sensitive scalps, aiding in rebalancing the scalp microbiome and reducing oiliness of the scalp – minimising shampoo overuse.

Everything you want – and nothing you don’t.

Free from parabens and silicone rinse-offs, our high-performing haircare products are skincare for your hair.
