Use of Minoxidil and finestride in liquid form (spray) post HT?

Hi all, just trying to figure out if and when I can start using liquid topical min/fin on my scalp post HT, I am getting some contradictory info. Saying I can use foam min 1 month post but liquid 6 months post op.

Also what are your thoughts on dermarolling, When to start post ht? Thanks
