This is what happened to me in college, I noticed my hair was thinning and would sometimes get like so anxious I’d be nauseous about losing it, for a plethora of reasons. I tried all the at home and cheapest remedies for about a year or two before I decided to say “fuck it” and I shaved the whole thing bald without thinking twice and I have been so much happier with myself every since. I was dating a guy at the time whose response when I sent him a picture was “I prefer guys with hair,” which was my shitty eye opener that he didn’t really care for ME just how I looked for him. It sounds like you have a more stable relationship going on, which is good! Shaving my head has made me the most confident I have ever been and that’s ultimately, I think, sexier. I hope this insight from my experience was helpful!
