I also suffer from extreme dry scalp and and dandruff! I usually use shamppo bars from heensooq ( the cocoved and sweet honey) but I also use the Shea moisture shampoo. It's sulfate free and it makes my hair sparkle w/o making it super dry.
Try prepooing w/ EVOO and Unrefined Avocaodo oil or deep conditioning BEFORE you wash our hair, as that can help combat dryness.
Unlike you, my hair is really, so I have to bee careful w/ how much oil I use. Try massaging your scalp moisturizing oils like EEVO, or EVCO ans see if that helps w/ they dry scalp.
Edit: I've used the argan oil shampoo and it didn't strip my hair at all. the condition did nothing for my hair though
