Do most men reach a Norwood VI or Norwood VII?

Hair loss is most directly associated with your family genetics and lifestyle. Not all men who experience balding will reach a NW 6 or 7 level as every man is a unique case.
In a paper recently published by the Aesthetic Surgery Journal, I described a screening method I use in determining the extent of your baldness and likely future scenarios. The test called the “FUE Shave Test” entailed shaving the head to a tight crew and visually observing the hair spread in the density and caliber of the donor areas.For an example of a NW 7 patient regaining a full head hair watch the video or read more about this method using the link below.

This can be variable due to many factors. I suggest seeing a hair loss expert to evaluate and go over your condition and provide you information about your best treatment options. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

Not all men will reach a class 6 or 7. This is dependent on many factors. Information such as your family hairloss history as well as your preventative regimen that you are on such as minoxidil use and other topicals can also determine where you end up.

The amount of genetic male pattern hair loss will depend on your genetic makeup. Some men are programmed to be Norwood Class 2 some Norwood Class 7 and many in between. The pattern you will eventually have will become evident by late 20's early 30's in most men. So the answer is most men will not reach Class 6 or 7 and yes it can stop at class 2. 

The Norwood patterns that were published by Dr. Otar Norwood were genetic patterns that were developed by people directly.  Contrary to popular belief that one evolves from, let's say from a Class 3 pattern into a Class 5 or Class 6 of Class 7 pattern, no such evolution occurs. People born with a Class 3 pattern of balding will not evolve into a Class 5 pattern of balding and will remain with a Class 3 pattern of balding.  The best example can be seen with men who have Class 7 patterns of balding (about 7% of the population).  These men develop these patterns well before they are 30 years old and this unfold as early as 19.
