Korean hair-loss functional ingredient 탈모 증상 완화
바이오틴ba-i-o-tin
On a Korean label: 바이오틴 = Biotin — B vitamin (비오틴).

What it is

A B vitamin. Korea lists it as an active ingredient for hair-loss functional cosmetics (탈모 증상 완화); the Korean dictionary also lists it as a hair- and skin-conditioning agent.

On a Korean label

The standard Korean name is 바이오틴. Its old name, 비오틴, is still used on many packs and in Korea’s list of hair-loss ingredients, so you may meet both spellings.

Korean rules

  • Korean hair-loss functional ingredient — Korea’s Ministry of Food and Drug Safety lists it as an active ingredient for 탈모 증상 완화 functional cosmetics.

Questions

Is 비오틴 the same as 바이오틴?

Yes — both are biotin. 바이오틴 is the current standard ingredient name; 비오틴 is the old one.

Will a biotin shampoo regrow hair?

Korean rules only let it claim to help relieve hair-loss symptoms. For biotin taken as a supplement, the US National Institutes of Health says there is little scientific evidence that it improves hair.
