What the AI looks for in Hair Treatment Oils
- Silicone serum vs pure oil
- Silicone-based oils such as cyclomethicone or dimethicone give slip, shine and frizz control. Pure plant oils nourish but feel heavier and can go rancid. Most 'argan oil treatments' are mainly silicones. That is fine, but know what you are buying.
- Weight for your texture
- Fine hair: one or two drops, on the ends only. Thick, curly or coily hair can take more and can use it on the mid-lengths too. Overapplication is the number one reason people say a hair oil made their hair greasy.
- Heat use
- Only rely on an oil for heat protection if it specifically claims heat protection. Otherwise use a dedicated protectant. Plain oils on hot tools can fry the hair rather than protect it.
- Scalp vs lengths
- Styling oils are for the lengths and ends. Use a product formulated for the scalp if you are treating the scalp. Heavy oils and silicones can clog the scalp and worsen dandruff in prone people.
Brands that matter
- Moroccanoil: The benchmark styling oil, available in Original and Light weights.
- Olaplex: Lightweight bonding oil aimed at chemically treated hair.
- Kérastase: Elixir Ultime luxury finishing oils.
- Josie Maran: Pure, single-ingredient argan oil.
- Mielle: Affordable oils aimed at textured hair.
What to avoid
- Rubbing pure coconut or olive oil into the scalp if you are prone to dandruff or seborrheic dermatitis.
- Using a palmful of oil on fine hair.
- Assuming 'argan oil' on the label means the product is mostly argan oil. Check whether silicones lead the ingredient list.
