Shampoo for flaky sensitive scalp

[KedsAndTubeSocks]

Please can anyone suggest a shampoo for my sensitive dry scalp. It doesn't seem like proper dandruff; it's dusty, rather than big flakes, iykwim. I've tried head & shoulders, and the body shop ginger one (which made it worse).
Any other good recommendations?

T -Gel is pretty good

Nizorel if T-Gel doesn’t work but that’s quite strong & behind the counter in boots. Works for really persistent dandruff though.

Used TGel this morning thanks, seems to have helped a bit. I'll persist!

Nizoral is really good.

Nizoral caused brittle hair and hair loss for me, turns out it's not great for sensitive skin

Watching with interest though because pharmacist can't seem to find something medicated to help solve the problem

Been using Kérastase Bain satin 1 shampoo because it's extra hydrating which has helped loads but hasn't got rid of the problem yet
