Scalp redness, oily scalp, painful scalp & the shedding. Libido is normal, body hair normal.I've been wondering this as well but it really does not make sense.
What are your symptoms exactly? The common symptoms of RH (acne, oily skin and hair, itchy scalp, intense shedding and high libido)? Sorry I am too lazy to browse.
What's striking in your case is that finasteride has worked for you in the past.
I went from holding my NW2.5 for years to going NW3/4a within 3-5 months of restarting. At the start I thought the shedding was due to stop loss but it's been months now and hard to ignore. I only take finasteride 2x weekly right now, trying to see if anything can help.
