Lol Rsheikh. How about feed the mithai, dab oil THEN put mehndi :D Best thing is to let a sister or cousin sit throughout the rasms & guide every person who comes to feed the mithai. It works better that way.
You don't rub oil, just dab your fingers & kind of comb it through the hair. Its a Punjabi tradition if I am not wrong.
hibiscus to the list add uptan as well.
LOL both ways yuck...would purposely wear my hair up so no one touches my hair and wont allow oil to be dabbed anywhere...def. do not want sticky hair nor do i want to eat oily mithai!! haha..lol
