it's hard to see from your pictures since you have long hair, but i don't really see it as being "far below baseline". when i first started treatment 3 months ago i had really bad shedding for 6 weeks.. i mean just ball of hair in the catcher and about 10~ hair on my hands after i applied shampoo. and 10 more on my hand after i finished rubbing minoxidil on my scalp.. and then it just magically stopped. just this morning i had ONE hair after i applied shampoo.
what kept me from going crazy and abandoning ship was the fact that i was seeing a doctor and to me i was doing the best i could to manage my hair loss by seeing a professional. it gave me a peace of mind. hang in there man, you dont want to look back in a few years and regret not sticking with some type of treatment. and hopefully what happened to you today was the beginning of the end of your shedding! maybe all that shedding was to make room for more healthy hair to grow out
