Reddit reviews Overcoming Body Image Problems including Body Dysmorphic Disorder (Overcoming Books)

I'd also suggest https://www.amazon.co.uk/Overcoming-Problems-including-Dysmorphic-Disorder/dp/1845292790/

I haven't read that book, but it's part of the Overcoming series which teaches self-directed CBT for various mental health issues.

Ok, I get what you're saying, but 'slight OCD' sort of isn't a thing. Either you meet criteria for the disorder as defined by the official Diagnostic manual or similar, or you don't have OCD. The 'D' is for disorder. If it's not dis-ordering your life (as in, causing you an actual problem going about your daily business) it's just part of natural human variations in mood and personality. Some people have a natural tendency to get fixated on things a bit, but there are specific features that distinguish OCD from just generally thinking about a thing you're interested in a lot. There's usually a massive element of guilt or fear to the OCD theme, so just having a lot of thoughts about a body part tends not to be OCD per se. Unless you also somehow believe your hairline is immoral, dangerous, or committing criminal acts when you're not looking :P

However, you're entirely right, having frequent obsessive irrational thoughts over part of your appearance IS usually classified as Body Dysmorphic Disorder (BDD), if the thoughts are strongly affecting you, intruding into your mind even when you'd prefer to think about something else, and present for long periods of time (like, multiple hours every day). Thinking that you're balding at 18 years old sounds pretty irrational, tbh. Also taking daily pictures of your hairline and repeatedly asking multiple professionals and people online to confirm that your hairline is ok, yet never being satisfied with their answers...these are suspiciously BDD-like traits. As is being 'afraid' to get your hair cut.

If this problem persists, it might be an idea for you to consult the BDD foundation (here's their website: http://bddfoundation.org/ ) for advice and resources, and possibly ask your doctor to refer you to mental health services. They will be able to confirm what your issue might be and help you with treatment to re-train your brain into a healthier patterns.

If you don't think it merits seeing a doctor yet, you can try DIY-ing the right therapeutic techniques with a self-help book. Assuming it is something along the lines of BDD (and if you get the book and none of the examples sound like you at all, obviously....reconsider), this one's written by a well-known expert in BDD and OCD and might be helpful to you: https://www.amazon.co.uk/Overcoming-Problems-including-Dysmorphic-Disorder/dp/1845292790/ref=sr_1_1?ie=UTF8&qid=1481808500&sr=8-1&keywords=body+dysmorphic+disorder
