Science supports the use of apple cider vinegar as a hair rinse. It could help strengthen hair and improve luster by lowering hair and scalp pH. It may also keep pesky scalp infections and itchiness at bay.
Prepare a solution by mixing ¼ cup of apple cider vinegar and ¾ cup of water. You can add ⅛ cup of lemon juice and a few drops of essential oil of your choice into it. Massage your scalp with this solution thoroughly. Leave it for half an hour before washing it off.
