If you have been researching hair loss and how to combat it, you may well have come across something called the Norwood Scale. But what exactly is this? The Norwood Scale is a set of images which depict the various stages of hair loss when it comes to male pattern baldness. It shows the levels of hair loss from the very minor (stage 1) to the more extreme (stage 7) which is also considered completely bald. 
The Norwood Scale is an important tool for clinicians who specialise in male pattern baldness and what to do about it. By understanding the degree of hair loss suffered the specialist will be able to offer a variety of different ways to slow down or reverse the process of hair loss. What advice you are given will depend entirely on what stage of hair loss on the Norwood Scale you have reached. It is also important to tell you practitioner exactly when you noticed that your hair was thinning, as they will then be able to work out the rate of hair loss too. This again can make a difference as to what treatment might be recommended.
The higher the number on the Norwood Scale the greater the hair loss. If you have reached stage 6 or 7, you may feel that there are no options left open to you. However, this is not necessarily the case. Many men find that even with an extreme amount of hair loss some of the more long term methods of reducing the problem can be used. This could include a hair transplant. However, scalp micropigmentation might be a better option since in a hair transplant donor hair is required. If the hair loss is extreme then the donor hair might not be available, but nothing can be determined for sure until you speak to an expert.
