Long hair also has its benefits though. Short hair is more comfortable during the summer because there's nothing hanging over your neck (if it's that short), so your neck doesn't get as hot and sweaty as it would if it had a layer of hair covering it up. But this exposes it to the sun a lot more, and that's why it is sometimes better to have long hair–to protect your neck from sunburn. Of course, that problem can be easily taken care of if you just wear sunscreen on your neck. There are benefits of having short hair and having long hair, but I would rather have short hair.
