Hair and Scalp Problems

My scalp is driving me crazy.It is dry and no matter how often I wash my hair it is still dry and is giving me dandruff. I guess I need to do what I hate putting on my hair which is baby oil. Why I hate it? Well, it makes me feel hot or warm not to mention makes my face greasy a little bit...no idea why is that? It is worse during winter! Do you, guys have any idea how to get rid of those flakes falling off my hair? Oh, by the way, my hair are falling off, too. I feel like I am going to a chemo or something! Well, hope these problems will stop soon.
