Am I Balding?

[jmt]

I have no experience with hair loss and no relatives who are bald. No one i know has said anything to me about it but I get nervous when I look at the top of my head and see my scalp. I'm not sure if I'm losing hair there or if it just looks that way because of my part and head shape. It's also hard for me to notice if I'm losing more hair than normal because I have long hair and long beard. Anyways I was wondering if any body with experience could give me an opinion on my these pics:

I should also mention that until now I've been relatively unhealthy eating on average only a meal a day and that I'm a vegetarian who gets too little protein. Until recently my hygiene was also lacking and I didn't comb my hair too much. I am 23 years old and do have a fair amount of stress from college. I'm sure that all factors in but as I said I'm new to this and know no one with any experience.

if your asking the question......I'm pretty sure you know the answer.

when i first started loosing hair I noticed my scalp felt sore in certain places. In those areas where that feeling persisted it always led to shedding and eventual balding of those areas. But by the looks of it it looks like you are experiencing a small amount of hair loss right now. Rogaine is great for the crown area in case you want to try and prevent further loss.
