I Sure Hope So. My Daughter Is 19 Years Old

I sure hope so. My daughter is 19 years old and has been loosing hair for the past year and it is definitely beginning to show with sparsities within her scalp. She is tired a lot also and is breaking out with acne something horrible even prescription meds for the acne are not helping at all. Her pediatrician just keeps telling her to get more sleep. Is there any other doctor that I can take her to for an indepth evaluation? Would and Endocrinologist be helpful?
