On the topic of BDD: since I noticed the first improvements, I stopped looking at my hair, because I became calm, which stopped the baldness. For this reason, I didn’t even take pictures for half a year, I just didn’t care. I knew my hair was getting better so I didn't have to worry.
Also, someone accused me of calling HRT the only way to deal with baldness in aggressive early cases. But it's not my fault that it's true. There is a Russian proverb "Better the bitter truth than the sweet lie"
If a guy is ready to do anything for hair, then he should be informed about what works and what does not. Otherwise, he will spend a lot of time, will be nervous for at least one year of testing useless drugs, and then he will still switch to HRT, or stop fighting. I've been through this myself. It would be better if they told me "Dude, this does not work" and I would not live with constantly shattered hopes.
Having created my branch, I will not teach anyone how to act. I'll just describe my path. And people will draw the conclusions they need and decide for themselves what they need to do.
