Tips for managing scalp psoriasis

I’ve recently ( in the last 8 months developed scalp psoriasis and an itchy painful scalp.
I’ve trialled
Goats milk shampoo
Head and shoulder itchy scalp
Anti fungal shampoo
None of which helped long term
I inject Bimzelx every 28days
Consultant had added
Methotrexate by injection, I have yet to start this
Any suggestions on anything that has good effect,are welcome
