Errrr, I am not really sure but I would try this:
In a bowl mix 2 tablespoons of gram flour with 2 tablespoons of rose water and 1 tablespoon of lemon juice. Mix well to form a paste and apply on your face, let it dry completely and rub it off with your fingers to get rid of facial hair. For best results, repeat this three to four times a week.
(I never tried this but my friend says it works.) I hope this helps!! Let me know the results!
