No. You will end up irritating your scalp. The Minoxidil will start to show effect in 3 to 4 months of using it.
No onion or garlic or lime or curd or any home remedies please, especially when you are on allopathic treatment. My experience is that the scalp gets irritated. You could decide any one (home remedies or allopathic treatment) according to your comfort.
ps: if home remedies worked in hair fall or (Androgenetic Alopecia ) then why don't the majority of the people have a headful of thick hair? :) Think about it.
