Zoryve questions

I started zoryve foam about 4-6 weeks ago and have noticed a huge improvement. However, I have some questions for those who have successfully used it:

• Do you need to use it every single night? I’ve been doing it once every couple of nights and while the redness and scaliness have cleared up, the itching and some mild flakes continue. Wondering if it’s about the frequency or length of time. I typically wash my hair every other day so don’t love the idea of every day but would if it will curb the itch.

• What’s the long term plan? Do you use it for maintenance eventually or stop altogether or do another round as needed or what? My dermatologist said to use it for a month and everything on hear says more like 2 but i haven’t seen anything about long term needs.

• What shampoo do you use during treatment? I’d love to go back to my old regular one that isn’t particularly SD-friendly but makes my hair feel great but don’t want that to have a negative effect on treatment. Dr had initially prescribed a steroid shampoo but I didn’t see a significant enough impact after a few weeks and I’m hoping to avoid steroids going forward as much as possible.

Thank you for anyone taking the time to read and reply!
