30 ml | Step 6: Treat | 10+ uses
A heavyweight, 100% natural oil treatment that transforms dry, frizzy curls in one simple step. Add 3–5 drops to your co-wash or leave-in and it becomes a deeply nourishing mask that quenches thirst, smooths frizz, and leaves curls soft, supple, and beautifully defined. Fragrance-free and handmade in the UK, a great addition to a pamper day/evening.
When curls feel parched or rough, Treat It delivers targeted, oil-only nourishment. The pure olive oil base floods strands with fatty acids and naturally occurring vitamins to cushion, smooth, and restore softness — without synthetic fragrance or fillers. Mix into Step 1 or 2 and you’ve instantly created a rich, masking treatment tailored to your curls.
Unlike heavy butters or silicone serums that sit on top, this protein-free, coconut-free formula sinks in and rinses clean, helping curls stay light, defined, and easier to style. Use as a periodic rescue when your hair needs more than everyday moisture — ideal after sun, swimming, or a run of dry weather.
Fragrance-free — clean, simple and calming perfect for a pamper day.
For: Dry, frizzy, brittle, or over-parched waves + curls needing serious moisture.
Not for: Hair that isn’t very dry, or those seeking a daily styling oil (choose Seal It or Magic Mask instead).
Add a few drops to your routine and get spa-level conditioning without adding extra steps. It works while you rest — leave on for at least an hour or overnight — then rinse for touchably soft curls that stay hydrated for days.
Ingredients:
Olea Europaea (Olive) Fruit Oil (pure olive oil — rich in oleic acid and naturally occurring vitamins A, B1, B2, B6, C & E for deep conditioning and softness).
Powered by Olive Oil to quench, smooth, and replenish — delivering lasting softness and frizz control.
Plus free from fragrance, protein, and coconut oil — keeps curls calm, flexible, and residue-free.
Every CGMC® formula rinses clean with our Co-Washes or sulphate-free Detox — no harsh cleansers, no dryness, no frizz.
Our CGMC® 7× Promise:
No Coconut Oil • No Sulphates • No Silicones • No Drying Alcohols • No Waxes • No Itchy M’s • No Parabens — for cleaner, softer, longer-lasting curls without dryness or frizz.

How to Use
On wet or damp hair, add 3–5 drops to your Co-Wash or Leave-In, mix in hands, then apply from roots to ends.
Leave on for at least 1 hour — or overnight for maximum hydration. Rinse thoroughly, follow with Step 2: Leave In Conditioner and Step 3: Styler.
If hair still feels dry, clarify with Detox next wash and repeat.
Treat It Deep Conditioning Oil is Step 6 in our 6-Step Cycle (1 Cleanse → 2 Condition → 3 Style → 4 De-Frizz → 5 Refresh → 6 Treat).
