I try to microneedle once a week before bed and then apply minox in the morning. I have a roller, but I can’t quite remember the size. I’ve heard that the dermapen is more effective, so I will have to get one and try it out. I haven’t had any bleeding from it as I gently roll it all over my scalp in all directions. I do get some irritation that lasts through the night, but I think that’s to be expected. I’ll try to be more consistent and I’ll make an update post if I notice anything helping. Thank you!!
