I clean the drains. (Actually, I do all the plumbing, because if I do it, it gets done. If Spouse does it, we spend the afternoon and evening at Urgent Care and I still get to do it the next day. Proprioception issues and DIY are a BAAAAAAAD combination.) I keep my hair between 10 and 26 inches long; Spouse gets a high and tight every 90-120 days, when his high and tight gets shaggy. We use separate bathrooms, because he really likes a steamroom bathroom, and the little bathroom is better for that.
I much prefer cleaning the long hair drain. Short hair may take a little longer to block, but it is like cement when it gets there. I hate beard hair more than I hate head hair. If full body depilation ever becomes a thing, I will think deeply about getting this household on that program.
Clean your drains.
