Lemon
Taking lemon in lukewarm water helps to restore your body’s natural PH levels to normal. And applying lemon juice on your scalp does the same. Lemon can be an effective treatment for dandruff as it balances the PH level of your hair and scalp.
Apply juice of half lemon on your scalp and sit for 25- 30 minutes, maybe you feel itch during this but that is normal and then wash your hair as usual.
