I havent washed my hair in about a week & when that happens my hair gets really oily & my head itches. i was just brushing my hair & a lot of strands came out at once. i have long very thick hair. how much is too much hair? should i be worried?

If you are experiencing itching and oily Sx's try washing your hair three times per week, but use a very mild shampoo and is hypoallergenic. I assume you bathe often? Basic hygiene is important to prevent itching and other Sx's.

Agree with Dr. Griggs. You need to wash your hair more often. If you have long hair, you may wash in the evening and let the hair dry naturally rather than using a hair dryer. Wish you good health!
