The only way I can really help is if you told me your daily hair routine :P
If you've been using heat, it sounds like time for a break. Hair loss can be a sign of malnutrition, depression, an autoimmune disease, so see a doctor about that.
Get a hair cut. Split ends are deadly to having healthy hair. If you don't cut them off, they'll commit suicide and break off on their own, leaving your hair shafts weak, brittle, and all busted up ><
Buy a sulfate free conditioner and shampoo. I also have fine hair and I use Sebastian Light for conditioner. It's expensive, but it lasts for a really long time. I use a dime sized amount for my hair and it just goes so far. If there's anything I splurge on, its conditioner lol. It's around 17 a bottle.
Also.. I KNOW this sounds crazy, but when my hair was really dry my stylist told me to just stop using shampoo often. If your hair is dry, shampooing too often keeps the oil from going down the shaft because it washes off. Use a little bit on your scalp, but don't lather up! My hair is pretty thin, so all the gross oils (like sweat and grease) kind of just roll right off.
Change your diet. Eat avocados! Google natural remedies and try them out.
Also I recently got a bottle of Moroccan Oil and it's SO good. It's natural, doesn't make your hair oily and works really well when blow drying and flat ironing. My hair is so shiny now :D
