Hi
I would suggest that you try Allergenics Preservative Free Emollient, Gentle Medicated Shampoo, with natural Phytosterols.
It's hypo allergenic, preservative free, 100% Natural origin, Dermatologically Tested, Allergy Tested and pH 5.5
. It's suitable for those prone to dry, itchy skin conditions, those with easily irritated, sensitive scalps and is free from harsh detergent. It's available in large high street chemists.
Hope this helps...
