Best alternative to T-Gel for scalp psoriasis now it's been discontinued?

[Goody2ShoesAndTheFilthyBeast]

Can't get proper coal tar soap any more and now t gel theraputic has gone too.

If you have psoriasis, what do you use?
Thanks.

This - absolute game changer

The Sea Magik shampoos have worked well, Jason’s brand too. Both from Amazon.

You could look at the Ameliorate range too - DH uses those. Available from Victoria Health among other suppliers.
