It's something I think most guys pretty much deal with. Most of the legit ways are pretty expensive, being implants and such.
Try using better shampoo and conditioners and using smaller amounts. I found my hair to be much healthier after I started using something called Nioxin, which you can get at any real hair care shops. I get mine at a place called Ulta and use system number 2 Shampoo and Conditioner.
It's a bit pricey, and the bottles look skinny, but I'm still on my first two bottles of it and this is after buying it back in March of this year using it every day. I've noticed a great difference as I'm no longer yanking hair out with my comb.
And if you do go that route, get a haircut before you start using it to get rid of the dead ends and start with healthier hair.
