Recently (within a half a year, or so I've noticed) I've had a thinning of my top, frontmost hairs. I'm a 19-year-old female. I will be going to the doctor soon, but would like some opinions for piece of mind. I'll give a bit of information to help: My dad is 64 with more hair than he can handle (he looks like a dandelion). My mother has always had thin hair, but not in patches..just naturally thin. I definitely have my dad's hair..his is wavy, thick and auburn (like mine) and hers is thin, blonde, and straight..so I'm really not thinking it's genetics. No female nor male in my entire family have had thinning hair at a young age. My first thought was something to do with hormones. I've had a struggle with slight premenstrual cystic acne (small nodules that wouldn't heal for 3 months) but I've since controlled it with Bactrim antibiotics. Maybe there's a correlation between my cystic acne (some say overproduction of androgens) and my hair loss? What symptoms would a female have if they overproduced androgens? My other guess was lack of nutrients..I'm a vegetarian who doesn't really eat any vegetables. I'm naturally thin, but not too thin, so I don't think it's a weight issue..but I really don't eat a balanced meal (I usually have burritos and spaghetti and ramen). I try to take supplements and drink something call a Green Drink but I'm not sure it's enough. My final idea was that it was either inflammation from dandruff (since I was young I had this, but I thought it went away..my scalp would only flake if I scraped at it and I began to think this might have been from conditioner build-up), folliculitis, or some other scalp bacterial/fungal infection. My main reason for thinking this is that the affected hair follicles sting and ache a little any time I flip my hair from one side to the other. It's really sensitive, only slightly painful, and I feel that the slightest touch could shed some hairs. Also, the other day I noticed a build-up of scaly dry skin that I had never seen before. I've been trying anti-drandruff shampoo for 4 days but I'm not sure whether this is helping. These symptoms seem indicative of an external, dermatic rather than an internal issue (such as those I listed above). Would I get this sort of tingly/irritated feeling if it was hormones/my antibiotics/malnourishment? I always thought folliculitis and infections would cause obvious flaking, sores, redness, etc... Just hoping for some input. I really hope this hair loss isn't permanent once I solve it :(. Thanks! I had bloodwork done a few months ago: -normal Thyroid hormone levels -slight Vitamin D deficiency -slightly anemic (something like a 10.9 where 11 was normal)
