Actually finasteride, nobody has ever told me, it was just me. My wife parents, coworkers (I know this is sad) said that all looks good and don't know what I am talking about. My problem is bathroom mirrors or any mirror in general and I constantly look & spend time to honestly brush my hair until I feel that it looks good to me. True BDD & OCD behaviors. I just feel recently that I may have some miniaturization in my crown because, yeah I have that split that shows scalp but it looks like one area maybe moving to the left a little and maybe developing an oval like right where that area shows in the photo. I went to the dermatologist back in January & she said that everything is fine in the back but I had her to focus on the other side of my head, where I thought something was going on but nothing. Drives me insane. If I would have some miniaturization going on next to my scalp split, I keep thinking maybe i should get some Rogaine because maybe it will thicken it up and put me at ease. I also have blood work scheduled for Thursday and haven't been taking any regular vitamins recently, which I know doesn't do anything for hair thinning but overall helps the entire body.
Anyways to answer your question, I am my own worst enemy when it comes to this.
