Hair loss can be a difficult and emotional experience for many people. One tool that is commonly used to classify the stages of hair loss is the Norwood Scale. Developed by Dr. O’Tar Norwood in the 1970s, the Norwood Scale is a widely recognized and accepted method for determining the extent of hair loss and the best treatment options. In this article, we will take a closer look at the Norwood Scale and the different stages of hair loss that it describes. (source)
What is the Norwood Scale?
The Norwood Scale is a classification system that divides hair loss into eight different stages. Each stage is defined by the pattern of hair loss and the amount of hair that remains on the scalp. The scale ranges from stage I, in which there is minimal hair loss, to stage VIII, in which there is almost no hair remaining on the scalp.
The Stages of Hair Loss on the Norwood Scale
- Stage I: Minimal hair loss. The hairline remains in the same place and there is no obvious thinning of the hair.
- Stage II: The hairline begins to recede at the temples. The hair in the front of the scalp is thinner than in the back.
- Stage III: The hair loss is more extensive and the temples have receded further. The hairline is now an “M” shape.
- Stage IV: The hair loss is even more extensive and the temples have receded even further. The hairline is now a “V” shape.
- Stage V: The hair loss is severe and the hairline has receded to the top of the head. The hair is thin on the top and front of the scalp.
- Stage VI: The hair loss is severe and the hairline has receded to the crown of the head. The hair is thin on the top and front of the scalp.
- Stage VII: The hair loss is very severe and the hairline has receded to the back of the head. The hair is thin on the top and front of the scalp.
- Stage VIII: There is almost no hair remaining on the scalp.

Norwood Scale – Understanding the Different Stages
It’s important to understand that the Norwood Scale is not a one-size-fits-all classification system. There can be variations and nuances within each stage, and some people may experience a combination of stages.
For instance, in stage I, there is minimal hair loss and the hairline is stable. However, some individuals may experience early thinning of the hair but with no clear recession at the temples. Similarly, in stage II, hair loss primarily occurs at the temples and in the front of the scalp. Some individuals may experience a more diffuse thinning of the hair rather than a clear recession.
In stages III to VI, hair loss becomes more extensive and the hairline recedes further. These stages can also be sub-divided into different variations, such as III vertex, IIIa, IIIb, and IIIc. In these stages, the loss of hair can be more severe in certain areas of the scalp than others, making it important to have an accurate diagnosis.
In stage VII, there is significant hair loss on the top of the scalp, and hair is only present at the sides and back of the head. In stage VIII, there is almost no hair remaining on the scalp, but some hair may still be present in the back of the head.
It’s crucial to recognize that everyone’s hair loss journey is different and it’s not uncommon for individuals to experience more than one stage of hair loss at the same time, so it is essential for a specialist to provide an accurate diagnosis.
Differentiating between Male and Female hair loss patterns
While the Norwood Scale is primarily used to classify male pattern baldness, it can also be applied to female hair loss. However, female hair loss tends to present differently than male hair loss. For example, while men experience a receding hairline, women tend to experience a general thinning of the hair, especially on the top of the head.
In addition, women may also experience diffuse hair loss that occurs all over the scalp, rather than a specific pattern of hair loss. It’s also important to note that women can experience hair loss as a result of hormonal changes, such as those that occur during pregnancy or menopause, which can further complicate the diagnosis.
In conclusion, The Norwood Scale is a helpful tool for understanding the different stages of hair loss and for communicating with a specialist about treatment options. However, it’s important to remember that hair loss patterns can be unique to each individual and a proper diagnosis from a specialist can help to determine the best course of action.
How to Use the Norwood Scale for Hair Loss Diagnosis
It is essential to consult with a specialist hair loss doctor or a licensed trichologist for a proper diagnosis and to find the most effective treatment plan. However, self-evaluation using the Norwood Scale can also be a useful tool to help you understand your hair loss and communicate with your doctor.
The Norwood Scale can be used to help determine the stage of hair loss and the best treatment options. While the scale is most commonly used to classify male pattern baldness, it
can also be applied to women experiencing hair loss. Keep in mind that while the Norwood Scale can provide a general idea of the extent of hair loss, it should not be used as a definitive diagnosis. A medical professional can provide a more accurate assessment and recommend the appropriate course of action.
In conclusion, the Norwood Scale is a useful tool for understanding the different stages of hair loss. By familiarizing yourself with the different stages on the scale, you can better understand the extent of your hair loss and communicate more effectively with your doctor. Remember, early diagnosis and treatment is key to preserving hair and preventing further hair loss. Consultation with a hair loss specialist and seeking appropriate treatment plans can help to improve the outcome.
Factors that Affect Hair Loss
Hair loss can be caused by a number of factors, including genetics, hormones, medical conditions, and certain medications. Male pattern baldness, which is the most common form of hair loss in men, is caused by a combination of genetics and hormones. Men with a family history of hair loss are more likely to experience male pattern baldness.
Hormones such as testosterone and its by-product DHT can shrink hair follicles, making them unable to support healthy hair growth. This can lead to a gradual thinning of the hair and eventual hair loss.
Certain medical conditions, such as thyroid disorders, iron-deficiency anemia, and autoimmune disorders, can also cause hair loss. In these cases, hair loss is often accompanied by other symptoms and can be reversed with proper treatment of the underlying condition.
Certain medications, such as blood thinners, antidepressants, and blood pressure medications, can also cause hair loss. In these cases, the hair loss is usually temporary and will stop once the medication is discontinued or the dosage is adjusted.
Treatment Options for Hair Loss
Once the stage of hair loss is determined using the Norwood Scale, treatment options can be recommended. The most common treatments for hair loss include medications, such as finasteride and minoxidil, which can help slow or stop hair loss and promote hair growth.
Hair transplantation surgery is also an option for individuals experiencing advanced hair loss. The procedure involves removing hair from a donor area on the scalp and transplanting it to the area of hair loss.
Another option is Scalp micropigmentation, which is a cosmetic procedure that involves tattooing a pigment on the scalp to create the appearance of a shaved head or short hair.
It’s important to note that not all hair loss treatments are suitable for everyone, and the best approach will depend on the individual case. It’s recommended to consult a hair loss specialist for personalized recommendations.
Hair loss can be a difficult and emotional experience, but understanding the stages of hair loss and treatment options can help individuals make informed decisions about their hair care. The Norwood Scale is a widely recognized and accepted tool for determining the extent of hair loss and the best treatment options. Keep in mind that early diagnosis and treatment are key to preserving hair and preventing further hair loss. With proper care and the right treatment, it’s possible to slow or even stop hair loss and regain a full head of hair.
In conclusion, the Norwood Scale is a widely recognized and accepted tool for classifying the stages of hair loss and determining the best treatment options. Understanding the different stages of hair loss and the factors that can contribute to hair loss is essential for making informed decisions about hair care. Keep in mind that hair loss patterns can be unique to each individual and a proper diagnosis from a specialist is crucial for determining the best course of action.
In cases of advanced hair loss, hair transplant surgery can be an effective option for restoring a full head of hair. Hair transplantation is a surgical procedure in which hair follicles are removed from a donor area on the scalp and transplanted to the area of hair loss. The procedure is typically performed using one of two techniques: Direct Hair Implantation (DHI) or Follicular Unit Extraction (FUE).
Hair transplant surgery is considered to be one of the most effective treatments for hair loss and can lead to natural-looking and permanent results. However, it’s important to keep in mind that the success of a hair transplant depends on various factors, including the extent of hair loss, the individual’s hair type, and the skill and experience of the surgeon.
It’s essential to have a realistic expectation of the outcomes and consult a board-certified surgeon with plenty of experience in the field. The surgeon will evaluate your hair loss pattern, medical history, and overall health to determine if you are a good candidate for a hair transplant.
In summary, hair loss can be a difficult and emotional experience, but understanding the different stages of hair loss and treatment options can help individuals make informed decisions about their hair care. The Norwood Scale is a widely accepted tool for determining the extent of hair loss, and hair transplant surgery can be an effective option for restoring a full head of hair in cases of advanced hair loss.
