FunctionBotanical

What it is — Onion Extract (INCI: Allium Cepa Bulb Extract) is a plant-derived botanical used mainly in hair and scalp products, with a long history in folk hair care.

What it does — It is included in scalp and hair formulas marketed around fullness and scalp support. The evidence behind these uses is limited, so it is best read as a traditional, supporting ingredient rather than a proven treatment.

Typical use — It appears in scalp tonics, serums and shampoos, usually within a wider botanical blend.

Who it suits / good to know — Generally suitable for most scalp types. Set realistic expectations and give any scalp routine consistent time. For diagnosed hair loss, a clinician can advise on evidence-based options.

Safety — DHALIORA grades it low risk: a botanical extract that is generally well tolerated. This reflects the ingredient in general and is not medical advice; patch-test first if you have plant sensitivities.

Why we grade it Low: Low risk - botanical extract/water, generally well tolerated.
