2. Lemon Juice
While the thought of pouring lemon juice on your irritated scalp may seem counterintuitive, experts recommend it as a way to combat itchiness (avoid lemon juice if there’s broken skin on your scalp, unless you don’t mind some stinging).
According to Reader’s Digest, you should massage 2-tablespoons of lemon juice into your scalp and then rinse with water, followed by a rinse of 1-tablespoon of lemon juice into 1-cup of water. Apparently the acidity of the lemons will balance the chemistry of your scalp, which also helps control dandruff.
