What did your strand do?

Tap it. I'll show you the one oil your hair can actually use.

It floated. Shut tight.

Pure Batana Oil
Your match · Low Porosity

Pure Batana Oil

★★★★★ 4.8 · 412 reviews

Nothing gets in. Heavy creams sit on top and grease your roots. Batana is fine enough to actually absorb.

Choose your size

Same oil, bigger bottle. The more you take, the less each drop costs you.

£23.00

Something went wrong. Try again.

3–5 drops on damp, warm hair. Scalp first, comb through. 2–3× a week.

It sank. Wide open.

Pure Castor Oil
Your match · High Porosity

Pure Castor Oil

★★★★★ 4.8 · 365 reviews

Everything gets in, nothing stays. Castor is thick and sealing — it caps the gaps so moisture stays put.

Choose your size

Same oil, bigger bottle. The more you take, the less each drop costs you.

5–8 drops on damp hair. Roots to ends, heaviest on the ends. 2–3× a week.

It hovered. Just right.

Pure Amla Fruit Oil
Your match · Medium Porosity

Pure Amla Fruit Oil

★★★★★ 4.7 · 198 reviews

Nothing to fix. Just feed it, or heat and colour will open it up. Amla is the maintenance oil.

Choose your size

Same oil, bigger bottle. The more you take, the less each drop costs you.

4–6 drops, wet or dry. Roots, then the lengths. 2–3× a week.

The bit nobody sells you

You were never the problem. The shelf was.

Porosity decides what your hair can let in. Nobody ever told you yours — because saying it out loud means admitting one bottle can't work on everyone. That one bottle is the entire business.

And what pried your cuticle open

Sulfates Strip the cuticle open. Every single wash.
Heat & bleach Pry the scales apart. They don't close again.
Silicones Seal product out. Fake the shine until you wash.

So you kept buying for a hair type nobody ever told you you had.

Three oils. Three different jobs.

Cold-pressed, nothing else in the bottle. Here's what each one actually does to the cuticle.

Cuticle shut tight
For low porosity

Batana Oil

American palm nut · Honduras

FeelLight. Fine. Absorbs fast.

DoesSlips past a closed cuticle instead of sitting on it and greasing your roots.

KnownThe Miskito hair oil. Softness and shine with no weight.

Cuticle wide open
For high porosity

Castor Oil

Cold-pressed castor bean

FeelThick. Tacky. Sealing.

DoesCaps the gaps in a raised cuticle so moisture stops walking straight back out.

KnownRicinoleic acid. Grip, thickness, less frizz halo.

Cuticle just right
For medium porosity

Amla Fruit Oil

Indian gooseberry · Ayurvedic

FeelMedium weight. Silky.

DoesFeeds the scalp and keeps the scales lying flat, before heat and colour lift them.

KnownVitamin C rich. Shine and less shedding.

Haven't done it yet?

One clean strand. A glass of water. Wait 15 minutes. Watch what it does.

Same hair. Right oil.

★★★★★

"Mine floated. Explains why every thick cream just sat there. Batana actually soaked in — first time ever."

Danielle R. · Low porosity
★★★★★

"Bleached for years, mine sank straight down. Castor killed the frizz halo I've had forever."

Marcus T. · High porosity
★★★★★

"Hovered in the middle. Got the Amla. Shiniest my hair's been in years and way less shedding."

Priya N. · Medium porosity

Before you ask

Mine sat between two.

That's medium. If it drifted slowly down, treat it as high and seal. Can't call it? The Trio removes the guess.

How long until I see something?

Feel it in a week. See it in three to four. Length takes two months — because length isn't grown, it's kept.

Coloured or bleached hair?

Yes. Bleached is almost always high porosity — that's exactly what Castor is for. Oils don't strip colour.
