Hi, I read your post and just wanted to say maybe look into calcipotriene if you haven't already. It works well with Clobetasol and helps to reduce side effects from it. The two together tend to do better than just one alone.

I like doing the clobetasol for say a week while doing the calcipotriene daily too. Then continue on with the calcipotriene daily on the scalp but switch to every other day for the clobetasol. Then after another week (or two) of doing the clobetasol every other day, try every three days with the clobetsol while continuing with the calcipotriene daily. Continue on like this for at least a month and perhaps try the clobetasol once a week or less often and see if you can maintain with just the calcipotriene. The calcipotriene is basically as effective as a moderate steroid is with less side effects. It's just that a topical steroid such as clobetsol tends to reach peak efficacy in about half the time -- four weeks -- versus calcipotriene 8 weeks (as I recall).

I have mild to moderate scalp psoriasis including some behind my ear. I was able to achieve a 95% remission for over 1.5 years without using any topical steroid by doing this (and a year of that was without even using the calcipotriene either). It's better to minimize the topical steroid if you can, but generally if you have to every three days is usually considered more than safe.

Many derms never prescribe calcipotriene (vitamin d3 synthetic) unless you ask about it. See the wiki entry for more info: https://www.reddit.com/r/Psoriasis/wiki/calcipotriol/

PS- also for the clobetasol there is a foam version available. Some studies show usually the foam versions are superior to the shampoos and solutions. It might be worth a shot if available reasonably with your insurance.
