Does onion hair oil actually work?

Yes · the sulphur in onion juice genuinely supports keratin production and scalp health. A small clinical trial showed onion juice twice weekly significantly outperforming tap water for hair regrowth. The effect is real but modest compared to Minoxidil. Best as a long-term scalp health practice.

How often should I apply onion hair oil?

2-3 times per week for hair fall treatment. Once weekly for maintenance. Daily application is unnecessary and can cause buildup.
