The key ingredient present in onion that supports hair growth is “sulphur”. It is significant for making hair stronger. Sulphur helps blood flow to the scalp, providing nutrients to the hair follicles, which promote resilient hair strands. It also contains antioxidants, several vitamins and minerals that support the scalp environment for hair growth.

Benefits of onion for hair

Improves blood circulation

The sulphur in onion improves blood circulation to the scalp, which supports better nutrient delivery to the hair follicles.

Onion contains an antioxidant named quercetin, which helps inhibit the production of DHT(Dihydrotestosterone). DHT is a hormone that encourages hair loss. Thus, consistent usage of onion on the scalp nourishes the scalp and prevents excessive hair loss, maintaining a healthier hair volume.

Reduces dandruff

The antifungal properties of onion may help control dandruff, promoting a healthier and flake-free scalp.

Regular application of onion has shown effective results in minimizing hair thinning, providing a fuller and denser appearance.
