Ross, keep us up to date and let us know how we can help. Like the others have said, it doesn't look like you have anything to worry about right now. If you can't shake the worry, it might be time to try something different like buzzing your hair or even shaving it.
Ross,
Welcome
Based on your photo, you have no worries
However, if you do lose it, as I did in my late 20's,(alot older now) it takes some time, but shaving your head is truly cool and based on the reception I have received from woman of all ages, they think so too.
So, in the meantime, enjoy yourself and whatever you do, be true to your self.
