The Norwood Scale is a set of images depicting the different stages of Male Pattern Hair Loss also known as Androgenetic Alopecia.


The rate at which men lose hair can vary widely; hair loss can begin as early as puberty and while some men may shed a lot of hair during their 20’s, up to a Type 3 or Type 4 on the scale; others may have no discernible hair loss until their early 50’s, advancing to a Type 6 or type 7 very quickly.


Regardless of the rate of hair loss, the pattern of hair loss is predictable. This is because Male Pattern Hair Loss is caused by hormones and genetic predisposition. One of the derivatives of testosterone is called dihydrotestosterone (DHT). It’s a key factor in hair loss.






Norwood Scale – Stages of Alopecia



Type I. Minimal hair loss
Type II. Insignificant hair loss at the temples
Type III. The first stage that requires treatment
Type III vertex. Receding hairline and thinning hair on the vertex.
Type IV. Bigger pattern on the vertex and hairline
Type IVa. More pronounced hair loss in the frontal temporal and crown area
Type V. Patterns at both sites are bigger but a thin division line is still present
Type Va. More pronounced hair loss in the frontal temporal and crown area
Type VI. The bridge is gone but several strands of short fine hair may remain
Type VII. The most severe form of hair loss. Little hair on the front or top of the head



A genetic predisposition to hair loss means the hair follicles on a man’s head have an increased sensitivity toward DHT, causing the follicles to shrink. As a result, hair becomes thinner, weaker and after several years the follicles get so small that they’re unable to grow any hair.


Despite not producing any hair, the follicles stay alive for a couple of years, so here is a chance that a carefully tailored combination of non-surgical, scientifically proven treatment may yield good results.


However, after about two years, the follicles that haven’t been producing hair will become dormant and you won’t be able to re-grow your own hair.


Patients will need a professional diagnosis to determine whether they may be suitable candidates for hair transplant surgery.
