Men Thinning Top – Surgical Plan

Why Do Men Have Thinning Top?

Hair loss on the crown ( also known as the vertex ) is one of the most common patterns of male androgenetic alopecia. It’s primarily driven by genetics and the hormone dihydrotestosterone ( DHT ), which gradually miniaturizes hair follicles in this region.

But crown balding isn’t just a cosmetic issue — studies have shown a possible link between vertex baldness and cardiovascular disease. Research suggests that men with significant hair loss at the crown may have a higher risk of coronary heart disease, especially if the balding starts early.

One notable physical sign that may correlate with this risk is a crease in the earlobe ( called Frank’s sign ). While not definitive, the presence of this diagonal crease has been associated with atherosclerosis in several studies, and when seen in men with crown baldness, it may point to underlying vascular issues.

Who Are Suitable For Hair Transplant ?

Crown ( vertex ) thinning is a common complaint in male pattern baldness, but not every man with hair loss in this area is a good candidate for transplant. Here’s a breakdown:

Men with:

  • Stable hair loss (not rapidly progressing)

  • Defined bald spot on the crown (not diffuse thinning)

  • Good donor density at the back and sides of the scalp

  • Realistic expectations (understand that 100% density may not be achievable)

  • Willingness to undergo maintenance therapy (e.g. finasteride) to prevent further loss around the transplanted area

Crown transplants can be rewarding in the right patient. Even moderate improvement in coverage can make a significant cosmetic difference, especially under overhead lighting.

Men with:

  • Extensive thinning across the entire top of the scalp, especially with poor donor supply

  • Unstable or rapidly progressing hair loss

  • Very fine hair and low follicular density in donor area

  • Unrealistic expectations, such as wanting full coverage with limited grafts

  • Reluctance to use maintenance medication — risking a “halo effect” where transplanted hair sits in a sea of thinning native hair

Remember:

  • Crown restoration requires more grafts per square cm to appear full due to the whorl pattern.
  • Patients should be aware that priority may need to be given to the front and mid-scalp if donor supply is limited.

Aesthetic Hairline Restoration Plans

Objectives
  • To improve coverage and visual density in the crown or thinning top area.

  • Restore natural whorl pattern when possible.

  • Prioritize strategic placement of grafts to maximize the visual impact of each follicle.

  • Preserve donor supply for future needs and frontal restoration if required.

Ideal candidates include:

  • Men with Norwood Class III Vertex, IV, V, or higher, with clearly defined crown bald spot.

  • Patients with stable hair loss and good donor density.

  • Those who understand the limited density achievable in the crown and have realistic expectations.

  • Men willing to commit to long-term medical therapy to stabilize further hair loss.

Poor candidates include:

  • Men with diffuse thinning over the entire scalp, especially if donor is weak.

  • Those with unrealistic goals (e.g., full crown coverage in one session).

  • Patients with early-stage hair loss or unstable progression.

  • Class III Vertex / IV: 1,200–1,800 grafts ( 2,400 – 3,200 Hairs )

  • Class V and above: May require 2,000–2,500+ grafts (3,600+ Hairs )


Surgical Tips

  • Graft density may be lower than the frontal zone, around 30–40 grafts/cm², due to the swirling pattern.

  • We avoid using excessive grafts just to chase low hairlines; long-term planning is more important.
  •  
  • Typically 1 session for moderate thinning.

  • Second session may be considered after 12–18 months for added density or expanding the coverage.
  • Primary: Crown (vertex) region

  • Secondary (if donor permits): Mid-scalp transition zone for blending effect
  • Though the crown is not part of the frontal hairline, recreating the natural spiral (whorl) pattern is essential for realism.

  • Frontal-midscalp priority must be respected — do not deplete donor for crown in younger patients.

  • FUE is the preferred method for crown work due to the small area and the need to extract selectively based on hair caliber..

  • FUT may be used in larger cases if donor density is good and multiple sessions anticipated.

  • Finasteride (oral): Strongly recommended to stabilize hair loss

  • Minoxidil (topical or oral): Encouraged to boost density and prevent further miniaturization

  • LLLT (Low-Level Laser Therapy): Optional, improves blood flow and may reduce post-op shedding

  • Biotin/Zinc/Nutritional support: For scalp and hair health

Norwood Class V

Before
12 Months After
  • Losing hair in area 1, 2, 3, and 4 – treatment is similar to Class VI except area 4 is the last priority.
  • This area is only visible on nodding or bending, requiring a lower density, or not at all if not enough donor hair.
  • Further session is optional. ( Pictures Above )

Norwood Class VI

Before
12 Months After

Losing hair in area 1 to 5 / 5v – usually not enough donor hair to cover the entire area. There are 2 options:

  • To fill in area 2, 3, 4 to look good in the front. This is suitable for tall people.
  • To fill in area 3, 4, 5, 5v to look good in the top. This is suitable for short people.
  • The remaining areas can be left alone or filled in later. ( Pictures Above )

Norwood Class VII

Before
12 Months After

Losing hair in area 1 to 5 / 5v – usually not enough donor hair to cover the entire area. There are 2 options:

  • To fill in area 2, 3, 4 to look good in the front. This is suitable for tall people.
  • To fill in area 3, 4, 5, 5v to look good in the top. This is suitable for short people.
  • The remaining areas can be left alone or filled in later. ( Pictures Above )

Norwood Vertex Variant

Before
12 Months After
  • This group loses hair in the crown ( area 5v, 5, 4 ) and retains the hairline ( area 2, 3 ).
  • Hair can be transplanted into area 4 and 5 to achieve good coverage.( Pictures Above )

Shock Loss in Hair Transplant

What You Need to Know & Accept

Shock loss refers to the temporary shedding of native hair following a hair transplant procedure. While it’s more frequently observed in women due to widespread miniaturization from Female Pattern Hair Loss (FPHL), shock loss can still occur in men — though it’s less common.

Shock loss is typically triggered by surgical trauma or stress to the scalp. Even when carefully performed, the procedure can temporarily disturb surrounding native hairs, especially if those hairs are already weakened due to:

  • Genetic miniaturization ( male pattern baldness )

  • Scalp inflammation or poor circulation

  • Nutritional deficiency or chronic stress

  • Recipient Area: Most commonly, native hairs near the graft sites may shed if they are miniaturized or in transition.
  • Donor Area: Rare, but possible in cases of overharvesting, aggressive FUE extraction, or if donor hair is already thin.

Onset: Typically 2–4 weeks post-transplant

Recovery: New growth generally begins around 3–4 months

Full regrowth: Usually achieved by 6–12 months

Most of the shed hairs return, often healthier and stronger with proper care and recovery support.

At our clinic, we take every precaution to reduce the chance and impact of shock loss:

  • Gentle and precise implantation to minimize trauma

  • Avoiding overpacking grafts into fragile native zones

  • Offering LLLT (Low-Level Laser Therapy) to enhance recovery

  • Advising targeted supplements and optional pre-op minoxidil for borderline areas

  • In most male patients, no. Shock loss is a temporary phase in the healing process.

  • However, if the affected hairs were already severely miniaturized, they may not return — not because of the transplant, but because they were nearing the end of their life cycle.

Doctor’s Comment

While not every man with crown thinning is at risk, it’s a good reminder to check blood pressure, cholesterol, and family history—especially if early crown balding is present.
