Shopping for Dettol soap

My dear has skin allergy and he tried some skin care product of soap but they are not suitable for him. He likes to use Dettol soap as so far it is best suit his skin. He is less caring for his hair as he fined his skin most important he works long hours and he has itchy skin at neck if he's feel hot. As he sweats he will find skin itchy and scratching can cause the bleeding too.
