The 7 Stages of the Norwood-Hamilton Scale for Male Pattern Hair Loss

The Norwood-Hamilton scale is the standard tool used to assess the extent of androgenetic alopecia (the most common form of hair loss in men) and predict its progression. This scale helps specialists recommend the most effective treatments to halt or reverse hair loss. It is applicable to all hair types.

Stage 1: No Hair Loss

In this initial stage, there is no visible hair loss, and the hairline typically mirrors the hair condition seen in adolescence. Whether you have a higher or lower hairline naturally, this does not indicate baldness. Most men experience no noticeable changes at this stage.

Stage 2: Early Recession

Slight hairline recession begins in this stage, particularly at the temples, forming a more mature hairline common in men in their 20s and beyond. The recession usually measures 1 to 2 cm. While some hair thinning may also occur at the vertex (top of the head), it's not advisable to consider a hair transplant at this point, as future hair loss may disrupt the results. Treatment options such as natural oils (e.g., rosemary oil) or far superior our daily Exosome oil which won, Best Aesthetic Industry Award 2024 may maintain hair health, though they won’t fully stop androgenetic alopecia. For the best approach, a clinical scalp analysis is recommended to understand the underlying causes of hair loss. One or two of our advanced hair loss treatments could significantly help hold onto your hair and slow things down at this stage.

Stage 3: Noticeable Hair Loss

At this stage, significant hair loss occurs either at the vertex or the frontal hairline, with further thinning at the temples. PRP (Platelet-Rich Plasma) or as recent clinical trials indicate, Exosome Therapy being further advanced, works faster with less treatments required. Low level laser treatments may also be effective in slowing hair loss and preserving the remaining hair. For some men, this may be the first time a partial hair transplant becomes a viable option.

• Stage 3 Vertex: Hair thinning primarily affects the vertex (crown) while the frontal hairline remains intact.
• Stage 3A: The frontal hairline recedes further, leaving the temporal areas exposed.

Exosomes have combined benefits of PRP, finasteride,and minoxidil by supporting hair growth, reducing inflammation and reducing the impact of DHT, though further research is needed to confirm that it blocks DHT as directly as finasteride. Clinical studies show it can help retain hair while stimulating dormant follicles plus increase the diameter of hair by up to 90%.  Some men will need one treatment, others more but average 3-4 is as far as studies across South Korea and America show with improvements still appearing 12 months later. Most men continued one maintenance session every three months to sustain the benefits knowing the systematic growing older process still continues.

Stage 4: Advanced Hair Loss

Stage 4 is marked by extensive hair thinning, particularly on the top of the head, leaving a narrow band of hair that still connects both sides of the scalp. Hair remains on the temples, though it may be receding. At this stage, our Advance Exosome Programme using combined modalitites can yield life-changing results, some men opt for hair transplants at this stage.

Stage 5: Significant Balding

Hair loss becomes more severe, but some hair remains on the sides and back of the scalp. A narrow strip of hair still connects both sides across the crown. Our Advanced Exosome Programme could help prolong hair retention and stimulate growth. Many men opt for a hair transplant at this stage.

Stage 6: The Classic Baldness

By this stage, the crown and hairline are nearly devoid of hair, with only a thicker band of hair remaining on the sides and back. This remaining hair, particularly from the back of the head is often used in hair transplants. Follicles from this area tend to be more resistant to balding not being impacted by DHT and are essential in restoring a natural looking hairline.

Stage 7: Complete Balding

Stage 7 is the most advanced form of androgenetic alopecia, where the entire top of the head is bald, but some thin hair may remain on the sides and back. Even at this stage, hair transplants are possible, though they often require a more substantial number of grafts and a highly skilled surgeon to achieve a natural look.

When is the Right Time for a Hair Transplant?

Hair transplant specialists agree not to wait until Stage 7. Ideally, transplants should be considered from Stage 4 onwards, when the hairline or vertex can be restored. Stage 3 is generally too early, as further hair loss may disrupt the results. If you opt for a transplant at Stage 5 or 6, you can expect to regain the appearance of Stage 3 or 4 hair. For Stage 7, although challenging, an experienced surgeon can still perform a transplant, but it requires a longer procedure and careful planning to achieve the desired density. Success ultimately depends on adhering to your surgeon's post-operative care instructions.
