How To Use
Five minutes, two or three times a week. That’s the whole routine.
Your Weekly Hair Ritual
HOW OFTEN?
2 - 3 times a week is the sweet spot. Daily use isn’t more effective — it just builds product on the scalp.
Oily scalp?
If your scalp runs oily, stay at twice weekly and always use it as a pre-wash.
Dry scalp?
If it runs dry or you have coily hair, three times weekly with an overnight soak suits you better.
How Long Should I Use It?
Give it a full 12 weeks before you judge it.
Hair grows around 1cm a month, and a follicle needs a complete cycle to respond to any change in its environment. That means:
Weeks 1–4 — scalp comfort improves first. Less itch, less flaking, less tightness.
Weeks 4–8 — hair feels stronger and less prone to breakage. You may notice less coming away in the brush.
Weeks 8–12 — short new baby hairs appear along the hairline and parting. This is the milestone most people are waiting for.
Beyond 12 weeks — keep going. The people who see the biggest change are the ones who never stopped.
Miss a week and nothing is undone. Just pick it back up.
Ideal if your experiencing
IS THIS FOR ME?
Almost certainly. Here’s where it earns its keep:
- Anyone noticing thinning at the
parting, temples or crown - Dry, brittle or heat-damaged hair
that snaps rather than grows - Sensitive, itchy or flaky scalps
that need calming - Hair that’s lost its softness,
shine or bounce - Every texture — straight, wavy,
curly and coily
Suitable for anyone building a consistent scalp and hair-strengthening ritual. Not suitable during pregnancy or breastfeeding without speaking to your GP first, as the formula contains rosemary essential oil.
What To Expect
KEY BENEFITS
- Scalp soundness
Creates the calm, balanced scalp condition that healthy hair depends on. Rosemary and sea buckthorn soothe irritation and help control flaking. - Stronger from the root
Castor and sweet almond oils coat and fortify the hair shaft, so strands resist the breakage that stops length ever showing. - Deep, non-greasy hydration
Lightweight enough to sink in rather than sit on top. No weighed-down roots, no film on the lengths. - Genuinely multi-use
Scalp treatment, pre-wash mask, overnight soak, shine finisher, frizz tamer, split-end sealer. One bottle, six jobs.
WAYS TO USE YOUR OIL
One oil, three routines. Pick the one that fits your week — or rotate all three.
The core routine.
Apply to a dry scalp 30–60 minutes before washing, massage for five minutes, then shampoo out. Best for oily or fine hair, and the fastest way to feel a difference in scalp comfort. Twice weekly.
The deep one.
Same application, but left in overnight under your Hair Halo. The extended contact time gives dry, coarse, curly and coily hair a much deeper conditioning result, and the silk bonnet keeps every drop where it belongs. Once or twice weekly, washed out the following morning.
The finishing touch.
Warm 2–3 drops between your palms and smooth over dry mid-lengths and ends. Tames frizz, seals split ends and adds shine. Use before heat styling as a barrier, or on damp hair before air-drying. Avoid the roots for this one.
Key Ingredients
Complete the ritual
PAIR WITH
Two products turn the routine into something you’ll actually keep up.
The massage is half the routine. The massager makes the five minutes easier on your fingers and works the oil right down to the scalp — and it works just as well on dry hair between treatments.
The overnight step, solved. Our silk bonnet holds the oil against your scalp all night instead of losing half of it to your pillowcase —and because silk doesn’t grip the hair the way cotton does, you wake up without the friction, frizz and breakage. If you’re doing overnight treatments, this is the one piece of kit you shouldn’t skip.
Frequently asked questions
Stop use and rinse the area. As with any new product, patch test on the inner elbow 24 hours before first use if you have a sensitive or reactive scalp.
Beard and brows, yes — a drop or two, massaged in. Avoid the lash line and keep it away from the eyes.
It makes a real difference. Without it a good share of the oil transfers to your pillow rather than working on your scalp, and cotton pillowcases create the friction that causes overnight frizz and breakage. The Hair Halo is designed for this exact step — silk, so it holds the treatment in
place and lets hair move rather than snag.
Almost certainly, yes — you’re just early. Scalp comfort improves first, strength follows, and visible new growth typically shows from around week eight to twelve. Hair grows roughly 1cm a month, so give it a full cycle.
Speak to your GP or midwife first. The formula contains rosemary essential oil, which is usually advised against during pregnancy and breastfeeding.
About three months at three applications a week, using it on the scalp as directed.
You can, but you don’t need to. Two to three times a week gives the same result without product building up on the scalp.
Not if you use it as directed. Eight to ten drops on the scalp is enough — most greasiness comes from over-applying or from applying to the lengths rather than the scalp. Use it pre-wash and it rinses away completely.
Shampoo before you wet your hair. Massage shampoo straight into the dry, oiled scalp, then add water and rinse. Follow with a second short wash if needed. Adding water first makes oil far harder to lift.
Yes. There’s nothing in the formula that strips or fades colour, and the conditioning oils are especially useful on processed hair. Leave 48 hours after a fresh colour service.
