itchy and tingly scalp

[crafter]

hi all, I've had an itch scalp for 2 years now. I've been using dut for several months but still itches like crazy. Having a shower soothes it, but once the hair dries the itch returns. I've tried nizoral, t-gel, head and shoulders, conditioners but no shampoo has helped. i've tried prescription anti-histamines too but haven't. So i can only think it's DHT hitting my follicles or anxiety/stress related. It's really getting me down

can anyone help?

thanks
