What It Means When Your Hair Falls Out

What's going on: If your go-to hairstyle is tight braids or a ponytail pulled back so tight it doubles as a natural facelift, you could be the source of your own hair troubles. It's called traction alopecia, and it's when the hair along your hairline starts to fall out because there's too much consistent force pulling on it, Nazarian says.

How to fix it: Simply loosening up your hairstyles won't solve the problem, but topical hair growth products, like those containing minoxidil, can make a difference. Ask your dermatologist what products he or she recommends. If you want to keep your hair as full as possible, check out these five other habits that can lead to hair loss too.
