How Bald is Bald? The Norwood-Hamilton Scale

Norwood Hamilton Scale

There is more than one reason why people lose their hair and even the same cause can affect different people to different degrees. The first step for anyone interested in a hair transplant is to assess the nature and degree of hair loss. Typically, hair loss is evaluated on a 7-point scale known as the Norwood-Hamilton Scale, it covers everything from no obvious hair loss, to complete baldness. During your free consultation at our clinic, we will begin by evaluating your level of hair loss.


What Causes Hair Loss?

Some of the other most common factors that can result in hair loss include:

  • Genetics
  • Hormonal changes
  • Certain underlying medical conditions
  • Infections of the scalp
  • Medications
  • Excessive stress


The Norwood-Hamilton Scale

The Norwood-Hamilton Scale is the most widely used classification system for assessing hair loss. It contains 7 stages of hair loss:

Norwood-Hamilton Stage 1

There are no visible signs of hair loss. You have a full head of hair, though some thinning may be present.

Norwood-Hamilton Stage 2

Hair has begun to fall out at the temples and some recession of the hairline is beginning.

Norwood-Hamilton Stage 3

Hair loss has become noticeable. Your hairline has receded from the temples resulting in the standard “widow’s peak” hairline associated with male pattern hair loss.

Norwood-Hamilton Stage 3 (Vertex)

Your hairline has not greatly receded, however, the top of the scalp may be experiencing significant hair loss.

Norwood-Hamilton Stage 4

The hair on your hairline and crown have become significantly thinner or even bald. These two areas are still separated by only a band of hair.

Norwood-Hamilton Stage 5

You have continued to lose hair at the hairline and crown. These two areas are separated by an increasingly thin line of hair.

Norwood-Hamilton Stage 6

Your receding hairline and vertex have connected. You are now nearly completely blad on top of the scalp, though some thin hair may remain.

Norwood-Hamilton Stage 7

Hair loss has progressed to the back and sides of the head leaving only a band of sparse hair.

Further, there is a Norwood-Hamilton Scale Class A. The primary difference here is that hair loss begins at the hairline and gradually continues backwards.


Who Qualifies For A Hair Transplant?

For those whose hair loss has not progressed beyond Norwood-Hamilton Stages 1 and 2, a hair transplant is generally unnecessary as any hair loss is unlikely to be noticed. The majority of hair transplant surgeries are performed on patients in the 3rd or 4th stage of baldness. For patients in the 6th or 7th Stage, hair transplants are unlikely to be a viable option as the hair remaining is simply too weak. Patients should seek hair restoration treatment no later than Norwood Stage 5.


What Options Are Available For Completely Bald Patients?

For patients at the most advanced stages of hair loss (Stages 6 and 7), there are still viable options for a hair transplant in Turkey. Hair follicles can be transplanted into the scalp from a patient’s beard or elsewhere on their body. Hair transplants from a patient’s beard are a popular choice for covering hair loss on the top of the scalp. However, these do not provide the most natural-looking results when placed on the hairline. For receding hairlines, the most popular alternative is to transplant hair from elsewhere on the body, most commonly, the chest.
