Itchy Scalp

To fight flakes—brought on by poor diet, stress and climate, among other factors—try a lemon juice and olive oil mixture in your hair. "The acidity in lemon juice helps rid your scalp of any loose, dry flakes of skin, while the olive oil moisturizes the [newly exposed] skin on your head," says Cox.

To Use:
Mix 2 Tbsp fresh lemon juice, 2 Tbsp olive oil and 2 Tbsp water, and massage into damp scalp. Let mixture sit for 20 minutes, then rinse and shampoo hair. Treatment can be applied every other week.
