Why is my hair weird??

hi there, well basically i have a concern...my hair is really weird and could show because i am unhealthy if your busy just answer this question: HOW DO YOU GET THICK HEALTHY HAIR? WHAT VITAMINS? and if you have more time then please read.. ...basically in the fringe..when it comes down..about 3/4 of my forehead are covered by my hair (i think its called bangers or something) but ye they all come out in strands of hair, not all together, and on the sides you can see my forehead because the fringe isnt covering that bit... so basically why does my hair not come out not straight and instead..different blades of hair..if its confusing look at this diagram
