use products that are for sensitive skin. Dove skincare help as the Ph balance is neutral in all their products and they are fragrance free. They also moisturise as well so no more dry, irritated or flaky skin.
Reply:depends what causes it. if it is just dryness and itching keep moisturised. if you use biological washing powder then switch to non-bio. it may be your body washing products, try the 'simple' range
Reply:you should know first what's the causes of your allergies..then ask for doctor's assistance..then drink medicine..
