How To Treat Hair Fall And Knee Bruises?

! ive been told by several people that these symtoms i have could mean i vitamin or hormone deficencies. do they? facts(about me): *im a 17 year old female *gone/finished through puberty *i am a dislexic(on a side note, im sorry for the spelling, unorganized words/thoughts, and grammar mistakes). *i have a healthy deit and i eat enough food. i care and watch what i put in my body so that means no cokes, burgers, hotdogs, and fast food ect. i mostly eat meats, freash and cooked veggies, dairy products, and a little bit of weat. symtoms: *my hair has been falling out. its gotten so bad every time i shower and wash it i end up with a handfull of it, also i get the same when i run my fingers through my hair as well. ive put into thought that hair goes through growth and falling out cycles throughout the year but its been 2 years since its begun and its only gotten worse through that period. -this is the one the conserns me the most since i used to have long and thick curly hair , its still curly but it has thinned out nodicably. *i have very sinsative joints, bruse the insides of them (knees mostly), and around my smaller joints they tinted a brown.*i have white spots on my nails, and the layers of my nails peel off. *as i said before i am dislexic(if that has anything to do with it) thank you if you can help with my situation or give any advicec on the supject!
