On the hair and scalp
What this formula brings
- 01
Invigorates the scalp with rosemary and peppermint
- 02
Fortifies strands with nine organic oils
- 03
Leaves hair shinier, softer and more resilient
Why this exists
The scalp is skin, and it needs the same kind of lipids and support as the face. When it is left undernourished, comfort at the scalp can feel compromised and the hair that grows from it can look dull, dry, and less resilient. This treatment is built to do more than add surface shine. Rosemary and peppermint provide the stimulating scalp action, while a blend of nine organic plant oils supplies the fatty acids and richer lipid profile needed by both scalp barrier and hair shaft. Sunflower, castor, argan, avocado, hemp, and sweet almond oils work together to condition without relying on heavy residue, giving the formula a functional role at the source of the hair rather than a purely cosmetic finish.
Inside the formula
The key actives
02
Peppermint Oil
Mentha Piperita Oil
Adds a cooling sensation during massage and supports the invigorating feel of the scalp application.
03
Sunflower Seed Oil
Helianthus Annuus Seed Oil
Acts as the primary carrier, helping the formula absorb cleanly while delivering lipid-soluble ingredients to the scalp surface.
04
Castor Seed Oil
Ricinus Communis Seed Oil
Brings viscosity and a coat-forming quality that helps condition the hair shaft and enhance visible gloss.
05
Argan Kernel Oil
Argania Spinosa Kernel Oil
Contributes lipid-rich nourishment and tocopherols that support shine and manageability across the lengths.
On the hair and scalp
Concentrated, but not heavy when used sparingly. It spreads easily through the scalp and lengths, then settles into a dry finish rather than a greasy one. The scent opens with rosemary and peppermint, then moves into a warmer woody base.
The application
How to use this
-
1
Section the hair
Apply to a clean scalp or to the areas you want to focus on, parting the hair so the oil can be placed directly at the roots.
-
2
Massage gently
Work the oil into the scalp with slow circular movements. The peppermint and rosemary create a noticeably fresh, invigorating feel during application.
-
3
Leave to absorb
Allow it to sit before styling, or use it as a pre-wash scalp treatment. Use only the amount your hair can absorb without heaviness.
-
4
Use regularly
Apply morning or night as part of your hair routine, adjusting the quantity to suit your scalp and hair length.
What to expect
On the hair, over time
Day 1
The scalp feels refreshed after massage, and the hair lengths look more polished once the oil has settled. Used sparingly, it should not leave the hair feeling weighed down.
Week 1
The hair can begin to look shinier and feel better conditioned through the mid-lengths and ends. The scalp application feels more familiar and easy to integrate into your ritual.
Week 4
With regular use, hair can appear more resilient and the scalp can feel better supported by the oiling step. The overall finish is typically more glossy and controlled.
The deeper detail
The formulation, the provenance, the standard
Formulation
Helianthus Annuus (Sunflower) Seed Oil, organically certified, forms the primary carrier : a light, high-oleic oil that absorbs cleanly and delivers the lipid-soluble actives efficiently to the scalp surface. Ricinus Communis (Castor) Seed Oil, also organically certified, adds the viscosity and coat-forming properties that protect the length of the hair shaft and contribute to the characteristic gloss. Persea Gratissima (Avocado) Oil, organically sourced, contributes oleic and palmitic acids that mirror the composition of the scalp's own sebum, promoting absorption without the congesting effect of heavier butters.
Argania Spinosa (Argan) Kernel Oil, organically sourced, is one of the most well-established hair treatment oils: its combination of oleic acid, linoleic acid, and tocopherols makes it a lipid-restoring and antioxidant active with documented benefits for hair surface shine and manageability. Cannabis Sativa (Hemp) Seed Oil, certified organic, provides gamma-linolenic acid, a fatty acid notably absent from most conventional hair oils, which supports scalp barrier integrity. Prunus Amygdalus Dulcis (Sweet Almond) Oil rounds out the carrier complex.
Mentha Piperita (Peppermint) Oil and Rosmarinus Officinalis (Rosemary) Leaf Oil, both certified organic, are the functional actives for scalp stimulation. Rosemary oil has demonstrated scalp circulation benefits in controlled trials; peppermint compounds this with a vasodilatory effect on the scalp capillaries that is perceptible as the cooling sensation during massage. Urtica Dioica (Nettle) Leaf Extract, also organically sourced, contributes additional scalp-supporting properties. Decyl Cocoate provides the dry-oil feel that allows the formula to spread thinly without leaving a heavy, greasy residue.

herbal
Rosemary and peppermint hit first, then clove and sandalwood underneath with something sweet at the end. My hair feels stronger after a few goes and the dull patch on my crown has cleared up. I like that it's nine organic oils rather than just one, feels more thought-through. Small bottle but you don't need much because it's concentrated, so it actually makes sense.

love it
Scalp feels more awake after massaging this in before washing and my frizz is a bit calmer too. wish it lasted longer, but a little goes a long way.

weekend saviour
My hair gets battered outdoors so the ends look brittle. This sorted the shine and the rosemary-clove combo smells dead nice.
-
sheen is real
Lengths look less dull now and the castor plus argan give a soft shine even in daylight. Peppermint tingles when you massage it in, then the rosemary hangs around in a calming way. Concentrated so a little goes far, but you do need to section hair properly to spread it.

properly refreshing
Rosemary and peppermint wake the scalp up without leaving it oily. My fine hair usually goes flat but this gives a cleaner finish. Clove and sandalwood stop it smelling medicinal.

Yes
Feels really nice and my curls still keep their shape after I use it on damp hair. Slightly oily at first, but it settles well and leaves my scalp comfortable.
