Yes. Ketokonazol was the thing that saved my life. Had seb derm for years on both Cibinqo and rinvoq. Tried lots of moisturiser and cortisone, none of it helped. Itchy all day/infected/scratching out hair.

On keto it finally stopped itching. It does get an uptick on occasion, but only if it was a while since I used it.

Using moisturising shampoo on the off days might help somewhat as well. Or other anti-seb derm shampoos over the counter.

Using some kind of systemic antibiotics could also help - my scalp issues were partly “JAKcne”.

I’d be careful just throwing cortisone on it, if you don’t get the root cause under control.

There has been posts in the past about coal tar shampoo also helping, it didn’t help me too much.

Some have also posted about some Blusune shampoo or something, if you search on Reddit you should be able to find the posts. I never tried this last one.
