If you suffer from male pattern baldness, being able to identify your level of hair loss as falling somewhere in one of the seven stages identified by the Norwood/Hamilton scale can help a doctor determine how the best treatment method. [2] X Research source There will be times when you have to explain your level of hair loss over the phone to a doctor or physician. Being able to point to a stage on the Norwood/Hamilton Scale will be helpful. [3] X Research source The Norwood/Hamilton Scale also protects against misdiagnosis. You can make sure your hair loss is following the pattern of male baldness and not merely the result of aging. [4] X Research source

Stage One, which sometimes goes unnoticed, is marked by a very minor recession of the hairline and does not require treatment. Unless you have a family history of baldness, you do not need to worry about Stage one. [5] X Research source Stage Two is marked by a triangular recession of the hair lining the frontal temporal areas. The hair around your ears will also recede by several centimeters. Baldness becomes more apparent in this stage. [6] X Research source Stage Three is the lowest level of hair loss needed for a person to be considered bald. Temples will be bare, only covered by sparse hair, and the hair towards the front of the head will begin to form a crown. Stage four is marked by these symptoms becoming more severe, and hair further thinning and receding around the temples and the front of the head. [7] X Research source In Stage Five, the band of hair that extends across the crown thins. Hair loss around the temples and the ears become larger and more noticeable. This continues into Stage Six, when the bridge of hair across the crown is totally lost. [8] X Research source Stage Seven is the most advanced form of hair loss. There is only a narrow band of horseshoe-shaped hair on the sides of the head and the back of the scalp. There may be some hair, forming a semi-circle, over both ears. [9] X Research source

The Ludwig Scale was made to address female baldness as the patterns of balding in females are often different than in males. Baldness is more a progressive thinning of hair in females. However, sometimes women’s hair thins and recedes similar to men’s hair, so the Ludwig Scale might not work.

Type I is marked by hair receding and thinning on the top of the head. It may be hard to notice at this stage, but you may notice a bigger white patch than usual when you part your hair. The frontal hairline usually does not recede at this stage. Type II is marked by thinning, shedding, and a general decrease in volume of the hair overall. Your center part will also continue to widen. Treatment may be necessary at this stage of hair loss. Type III is the most extreme type of female hair loss. Hair is so thin it may not cover the scalp and will be noticeable to most people. Hair will also continue to thin and lose moisture.

Advanced baldness is rarely seen in patients, but it’s marked by almost no hair being present on the crown or the top of the head. Some women experience a gradual receding of the hairline, much the same way as baldness occurs in male patients. If this is the case for you, ask a physician if you should use the Norwood/Hamilton Scale instead to measure your hair loss.

Usually, the tools will allow you to put in basic information such as your age and whether or not baldness runs in your family. [12] X Research source The tool will also allow you to select your level of baldness, based on visual aids provided as well as multiple choice questions. [13] X Research source The tool will give you a level of baldness and suggest treatment options. However, you should never undergo any hair loss treatment without first consulting your regular physician. [14] X Research source

Your doctor might have you take a daily questionnaire, where you choose answers from a series of multiple choice questions regarding your level of hair loss. While questionnaires are easy and non-invasive, they are highly subjective and may not provide you with an accurate measure of hair loss.

Most people lose about 100 strands of hair a day and if you’re losing more you may be at risk for baldness. [16] X Trustworthy Source PubMed Central Journal archive from the U. S.

A hair pluck test, known medically as a trichogram, involves taking hairs from specific parts of the scalp after five days of using a specialized shampoo. The hair is then evaluated in a lab to assess the level of hair loss. [19] X Trustworthy Source PubMed Central Journal archive from the U. S. National Institutes of Health Go to source A UAT exam involves marking a fixed area on the scalp with a fiber tip pen. Then, all the hairs within the line are evaluated individually with tweezers or other devices at a doctor’s office. While this can provide an accurate measure of hair loss, it can also be quite painful. [20] X Trustworthy Source PubMed Central Journal archive from the U. S.
