What is the Norwood Scale?

Male pattern hair loss, sometimes seen at younger ages and sometimes at older ages, is the most common type of hair loss among men. Early diagnosis is very important in hair loss as well as in every health problem. Published by Dr. O’Tar Norwood in 1975, the Norwood Scale is the most widely used classification for hair loss in men. The Norwood Scale, specially developed for men and classified in different types of hair loss, still maintains its validity today.

Norwood Scale Show Your Hair Loss Level

The Norwood Scale has a total of 12 different shedding types, with grading levels ranging from 1 to 7. Norwood Scale gives an idea of what treatment should be applied for hair loss as well as determining the level of hair loss. If the falling out of your hair has progressed, it might be difficult to obtain your fallen-out hair by medication. In such cases, people are recommended to have hair transplant. If your hair loss problem is still at the beginning, that’s good news for you!
