Key takeaways
Canadian-American actor Will Arnett has had a lengthy TV career, starring in popular shows from Arrested Development to Bojack Horseman, as well as voicing Batman for the Lego movie franchise. Over this time, his hairline has changed significantly, just as it does for millions of men affected by male pattern baldness.
But despite his visibly receding hairline, Will Arnett has never had extensive hair loss. So how is he keeping his hairline in check?
Will Arnett hasn’t spoken publicly about any hair loss treatments he’s had (or hasn’t had), so we may never know for sure. But there are a few signs Will Arnett has had at least one hair transplant over the years. His hairline appears fuller and straighter now than it has in the past, which isn’t typical for a naturally ageing hairline.
Let’s look at how Will Arnett’s hairline has changed over the years, and whether it’s likely he’s had a hair transplant.
Will Arnett broke into the TV and film industry when he was in his early to mid 30s, by which point his hairline had already started to recede. But it has made a decent recovery since then, so let’s break down the ebbs and flows of Will Arnett’s hairline over the years.
Photos of Will Arnett in his early to mid 30s already show clear signs of male pattern baldness. His hairline and temples have started to visibly recede, with thinning around his frontal hairline:
Around this time, Will’s hair is following the pattern of hair loss consistent with androgenetic alopecia. The Norwood Scale shows typical progression of hair loss in men with pattern baldness. Between 2003 and 2005, Will Arnett appears to be around Norwood stage 3:
Just one year later, however, Will Arnett appeared on the red carpet sporting a straighter hairline. This is likely due to a hair transplant to tackle his temple hair loss, which had begun to veer into his mid-scalp:
It’s possible that Will Arnett achieved this result by using finasteride or a similar treatment, though a hair transplant is probably more likely. Finasteride tends to be most effective in the very early stages of hair loss, and is best for helping you retain existing hair, although finasteride can regrow hair in some cases [1-2].
It’s likely that Will Arnett uses finasteride and/or other non-surgical hair loss treatments to maintain his hair, as his straighter hairline was still going strong six years later:
Finasteride is a drug that limits the activity of the 5-alpha reductase enzyme. This enzyme is responsible for converting testosterone to dihydrotestosterone (DHT). DHT binds to androgen receptors within the hair follicles, causing them to shrink and stop producing hair. Over time, these changes can become permanent. This is the key mechanism behind male pattern baldness.
By limiting the amount of DHT in the body, finasteride can slow or stop hair loss, and may even promote regrowth in follicles that haven’t suffered permanent miniaturisation.
Many patients are advised to use finasteride after a hair transplant to maintain the native hair surrounding their transplanted grafts, keeping their hair thick and full for as long as possible.
Throughout his 40s, Will Arnett started showing signs of a more pronounced M-shaped hairline. This is a common development in those with hereditary male hair loss:
Certain hairstyles — including the sideswept and swept-back looks favoured by Will Arnett — can accentuate an M-shaped hairline, making hair loss more obvious. While hair transplant surgery is often an option at this stage of baldness progression, many men experiment with hairstyles that hide their receding hairline before opting for surgery.
Will Arnett’s hairline looks improved since 2019, with ideal fullness and shaping for a mature hairline. Though it still has a subtle M-shape, his temples are a little fuller, with more density around his frontal hairline, too. This suggests Will Arnett may have had another more recent hair transplant to top-up his hairline:
It’s not uncommon for men to have multiple hair transplants, whether it’s due to ongoing native hair loss or the need for hair transplant repair. According to data from the International Society of Hair Restoration Surgeons (ISHRS), almost 31% of patients had a second hair transplant procedure to achieve their desired results in 2024 [3]. Nearly 2% required three or more procedures.
We don’t know for sure, but it’s possible Will Arnett has had two hair transplants. One probably took place around 2005, while the other was more recent, possibly taking place between 2020 and 2025.
Will Arnett has never confirmed any details of a hair transplant, but if he did have hair restoration procedures around 2005 and 2020, it’s possible he’s had both FUT and FUE to restore his hair.
In 2005, FUT was much more common than FUE. ISHRS data shows that the strip method (FUT) was used in more than 90% of procedures around this time [4]. Today, however, FUE is by far the most popular method, being used in more than 85% of surgeries [3]. So FUT was probably chosen for Will Arnett’s first transplant, while FUE is more likely to have been used for his more recent procedure.
Though there are important differences between FUE and FUT, both are still commonly used. FUE results in less visible scarring, which is a key reason that it’s overtaken FUT in popularity. But FUT is still a valuable option, particularly for women (as the wound and subsequent scarring can easily be hidden beneath long hair) and those with Afro-textured hair (as FUT is less likely to damage the grafts on extraction).
Based on his age, hair type, and extent of hair thinning, we estimate that Will Arnett likely had around 3,000 to 4,000 grafts transplanted in total across two hair transplants.

Will Arnett hasn’t revealed which clinic or surgeon performed his hair transplant (if any), but it’s likely to have taken place in California. Hair transplants in Los Angeles are popular with many of the celebrities who live and work in the area, and many of the world’s most skilled hair transplant surgeons work out of clinics in and around Beverly Hills.
Looking at the changes in his hair, it seems likely that Will Arnett uses some kind of non-surgical hair loss treatment to maintain his native hair. Despite thinning around his temples and hairline, his hair loss never seems to have progressed into a bald spot on his crown, or significant thinning through the mid-scalp.
As a result, it’s likely Will Arnett has used finasteride, minoxidil, or other non-surgical treatments to look after his remaining native hair.
There’s no doubt that hair transplants are becoming more mainstream. This is helped by the rise in celebrity hair transplants, with dozens of actors, athletes, and reality stars coming clean about their procedures. Knowing that thousands of other people are affected by similar issues with their hair — and are taking steps to combat them — helps reduce the stigma around hair transplantation.
For example, England cricket captain Ben Stokes has spoken about his hair transplant and how it’s helped improve his mental health, while comedian Lloyd Griffith recently revealed his hair transplant from Harley Street’s Wimpole Clinic. Joel McHale’s hair transplant has also been confirmed by the actor himself.
Former Premier League footballer Rob Holding also had a hair transplant, and credits the Wimpole Clinic with restoring his hairline:
But big name advocates aren’t the only reason hair transplants are becoming more popular. Advances in technique and technology have made these procedures much more accessible and less invasive. Most procedures take less than a day, and many patients are back to work and other activities less than two weeks later. Plus, hair transplants are much more affordable than you might think — the average cost of a 1500 graft hair transplant is less than £5,000.
At the Wimpole Clinic, our surgical teams have transformed the hairlines of thousands of patients, with more than 20,000 procedures performed over more than 50 years. So if you’re looking for an experienced, trusted team to perform your hair transplant, look no further.

Photos of a young Will Arnett suggest his natural hairline is fairly straight, rather than following the natural V-shape of a traditional widow’s peak. However, a widow’s peak is often confused with a receding hairline, so it’s easy to mix up the two.
Will Arnett currently has a minor M-shaped hairline: a highly flattering mature hairline on men in their 50s and 60s. Learn more about the difference between a mature vs receding hairline.
Will Arnett’s longtime friend and collaborator Jason Bateman has naturally thick, full hair. Despite being a similar age to Will Arnett, Jason Bateman’s hairline has remained thick and full over the years, and there’s little evidence that he’s had a hair transplant to achieve this.
