Besan, or gram flour, is known for its cleansing properties and ability to stick to fine hair, while turmeric slows hair growth. Mix 2 tablespoons of besan with a pinch of turmeric and enough milk or rosewater to form a thick paste. Apply on your face, let it semi-dry and gently scrub off using circular motions. Repeat 3 times a week. Over time, this ubtan weakens hair roots, making the hair fall off naturally and gradually reducing regrowth.
