Hairline transplant: getting the design right

What a hairline transplant involves

A hairline transplant rebuilds the front edge of your hair, and sometimes the temple areas either side, using grafts moved from the back of your head. The grafts are harvested with FUE or FUT like any other transplant. What makes hairline work different is the design.

The hairline frames your face, so it is the part of a transplant people notice first. A well designed hairline should look like it has always been there. The International Society of Hair Restoration Surgery (ISHRS) describes the ideal restored hairline as one that is "just there", blending in without drawing attention to itself.

The design decisions you make with your doctor, where the line sits, how it is shaped and how it fits with future loss, matter more than which harvesting method is used.

Why an age-appropriate hairline matters

The most common design mistake is putting the hairline too low. The ISHRS says a frontal hairline should not be placed lower than your original hairline, and that it may be set a little higher if there is doubt about how much donor hair you will have for future loss.

A peer-reviewed paper on repairing unfavourable transplants makes the same point from the other side: high hairlines rarely look unnatural, while low hairlines can be a major problem. The same paper describes ignoring the fact that hair loss is progressive as one of the most common errors in judgement.

A hairline that looks right at 25 can look out of place at 50, when the hair behind it has continued to thin. A slightly higher, mature hairline tends to age better and leaves more donor hair in reserve. This is one reason doctors are cautious with transplants under 25, and why the StatPearls review from the US National Library of Medicine recommends a conservative, natural hairline so the result lasts.

How a natural hairline is designed

A natural hairline is not a straight line or a neat curve. Doctors use a few principles to recreate the way hair actually grows at the front of the scalp.

• Facial proportions. The ISHRS refers to the rule of thirds, where the face is divided into roughly equal parts from chin to nose, nose to eyebrows and eyebrows to hairline.
• Irregularity. Recipient sites are made in a random, irregular pattern rather than a line, so the edge looks soft.
• Single-hair grafts at the front. The ISHRS notes that single follicular units are often used to form the hairline, with multi-hair grafts behind them for density.
• Angle and direction. StatPearls describes frontal hair angled forward at a low angle, around 15 to 20 degrees, so it lies naturally rather than sticking up.
• Shape. Men usually have a sharper recess at the temples, while women's hairlines tend to be more rounded. Our female hair transplant guide covers the differences.

The ISHRS recommends the doctor draw the proposed hairline on your scalp before surgery so you can see it and agree on it. Take your time at this step, look at it from several angles, and ask how it would look if you lost more hair behind it.

It also helps to bring older photos showing where your hairline sat before it started to recede. They give you and the doctor a reference point, and a reminder that the aim is a believable hairline for your age, not the one you had at 18.

Temple points

The temple points are the small triangles of hair that point forward above each ear, below the frontal hairline. Loss here can make a face look older even when the front has held up well.

Temple work is detailed. StatPearls notes that hair in the temple area points downward, so grafts need to follow that direction closely. The peer-reviewed repair literature lists ignoring the angle where the frontal hairline meets the temples as a design error, because it produces a flat, wig-like front.

Rebuilding the temple points adds grafts and suits some people well, but it also commits donor hair to an area that can keep receding. Discuss whether they belong in your first procedure or are better left for later.

Graft counts in general terms

How many grafts a hairline needs depends on how far back the treated zone goes, how much native hair is left, the density you are aiming for and the character of your hair. Victorian Government health information notes that thick hair generally gives better results than thin hair.

A hairline-only case usually needs fewer grafts than a plan that also covers the mid-scalp, but it is still dense work, because the front is where density is most visible. StatPearls gives a target recipient density of roughly 30 follicular units per square centimetre as a working guide. Your doctor will estimate a figure after examining you.

For typical ranges by stage of loss, see how many grafts do I need and the Norwood 3 page, which covers recession concentrated at the front and temples. Cost follows graft numbers, so our cost guide is the next step for pricing.

Planning for loss behind the new hairline

Transplanted hair from the donor area tends to keep growing, but the native hair behind a new hairline may not. If the mid-scalp keeps thinning, you can be left with a strip of hair at the front and a gap behind it, which can look odd and may need more surgery to fix.

The ISHRS notes that a restoration plan should account for your pattern of loss and the likelihood of future procedures. A doctor may also suggest medication to slow further loss, and a GP or dermatologist can talk you through that. Our second hair transplant guide covers planning over several procedures.

What to discuss at your consultation

• Where the hairline will sit, and why that height suits your age and face
• How it would look if you lost more hair behind it in ten or twenty years
• Whether temple points should be included now or later
• The estimated graft number and how much donor hair it uses up
• Who designs the hairline and who makes the recipient incisions
• What density to expect, and when, given the usual growth timeline

The ISHRS stresses that good results need full understanding and agreement between doctor and patient, and advises against pushing for a celebrity-style or unnaturally low line. For a broader checklist, see our questions to ask.
