Hair oil, the Korean way: less than you think, lower than you think
Korean hair-oil use is deliberately restrained: a few drops warmed between the palms and pressed through the mid-lengths and ends, never the scalp, usually on damp hair after washing and again in tiny amounts on dry hair for shine. Camellia — 동백 (dongbaek) — is the heritage oil behind the habit. Oil coats and smooths the hair; it does not feed it.
The camellia habit
동백 (dongbaek) is the camellia, and camellia seed oil is Korea's heritage hair oil, historically smoothed onto long hair to dress it and keep it glossy. It is high in oleic acid, which makes it feel light and sink in quickly rather than sitting on the surface like a heavier oil. Camellia groves in the warm south of the country are still a seasonal tourist draw, and the oil remains on sale — now more often blended into modern serums than pressed and used neat.
Before the wash or after
Oiling before shampooing serves a different purpose from oiling after. A pre-wash oil limits how much water the hair takes up, and repeated swelling and re-drying is part of what roughens a cuticle over time. Coconut oil has the best evidence here, since its fatty acids penetrate the strand and reduce protein loss during washing; camellia, argan and the rest are far less studied and mostly act as surface conditioning. Applied after washing, any of them sit on the outside, cutting friction and adding shine.
How much, and where
Two or three drops for fine hair, a little more for thick or long — warmed between the palms, pressed into the mid-lengths and ends, with whatever remains smoothed over the surface. Nothing at the roots unless you are deliberately doing a pre-wash treatment. Damp hair takes oil more evenly than dry, and a second pinpoint application on dry ends is how the glossy Korean finish is usually achieved. Too much reads greasy in any light and cannot be corrected without washing again.
What oil does not do
Oil does not nourish hair. Hair is not living tissue and has no route to take up nutrition, so ingredient lists boasting vitamins are decorative. What oil does is coat the strand, reduce friction between hairs, discourage water from moving in and out — which is most of what frizz control means — and reflect light. All real, all cosmetic, all gone at the next wash. Split ends stay split; only scissors deal with those. Judged as a finishing product, hair oil is one of the better things on the shelf.
