Crown hair transplant: what makes the crown different

The short answer

A crown hair transplant moves grafts into the thinning or bald area at the top and back of the head, also called the vertex. It is possible and often worthwhile, but it is harder to get right than work at the front. It tends to need a lot of grafts for the visual change it delivers, the pattern of loss there can keep expanding, and many doctors prefer to treat the front first.

That does not mean the crown should never be treated. It means the crown needs careful planning around your age, your likely future loss and how much donor hair you have to spend over a lifetime.

A doctor needs to examine you to judge whether crown work makes sense now. The points below explain what they will be weighing up.

Why the crown is harder

At the crown, hair grows out from a central whorl in a spiral, changing direction over a small area. Grafts have to follow that pattern closely or the result looks disordered. That makes the design and placement slower and more exacting than at the hairline, where hair broadly points forward.

The way hair lies also works against you. At the front, hairs overlap each other in one direction, so each graft adds to the look of coverage. At the crown, hairs radiate outward from the whorl and part naturally, so scalp shows through more easily, especially under overhead light.

Finally, the crown is often a moving target. In many men it keeps widening over the years, and the edge of a treated area can end up surrounded by new thinning.

Graft demand at the crown

Because of the whorl and the way hair parts there, the crown tends to take a large number of grafts for a comparatively modest visual change. Treating a wide crown can use up a big share of your donor supply.

That matters because donor hair is finite. An International Society of Hair Restoration Surgery (ISHRS) article puts the grafts available from the back of the head at roughly 6,000 to 8,000. The ISHRS also warns that hair put into the crown at a young age can be inappropriate and use up too much valuable donor hair, leaving too little for the front if loss progresses.

How many grafts your crown needs depends on its size, the hair left in it and the density you are aiming for. See how many grafts do I need for ranges by stage, including Norwood 5, where the front and crown thinning are starting to join. Cost follows graft numbers, so check our cost guide once you have an estimate.

The progression risk

The biggest risk with crown work is not the surgery itself but what your hair does afterwards. Transplanted hair comes from the more resistant donor zone and tends to keep growing, but native hair around it may keep thinning.

The StatPearls review from the US National Library of Medicine advises that grafting only the vertex should generally be avoided, because it can use donor grafts prematurely and risk a doughnut appearance, where a treated patch ends up surrounded by a ring of new baldness. A peer-reviewed paper on repairing transplants also warns that overtransplanting the back of the scalp in a young patient can look bizarre as they age.

For this reason, doctors often want your loss to be stable before treating the crown, and may suggest medication to slow further loss. A GP or dermatologist can talk you through the options and how long they take to show an effect.

DermNet, the dermatology reference site, lists progressive balding in untreated areas among the recognised downsides of hair transplant surgery. It is worth being patient with the crown in particular. Transplanted hair sheds in the first weeks and grows slowly, so it takes many months before a crown result can be fairly judged. Our results timeline explains what happens month by month.

Why the crown is often done after the front

Many restoration plans treat the front and mid-scalp first and leave the crown for later, if at all. There are three main reasons.

• The front frames your face. A stronger hairline and front usually makes more difference to how you look than the crown, which you rarely see yourself.
• Donor budget. Keeping grafts in reserve means the front can be protected if loss progresses. Spending them on the crown first can leave you short later.
• Time to judge. Waiting shows how your crown is behaving, and whether the first procedure has grown as expected, before committing more donor hair.

When the crown is treated later, it is usually as a planned second hair transplant, after the first result has matured.

Who crown work tends to suit

Crown transplants tend to make more sense if you:

• are older, with a pattern of loss that has been stable for some time
• have a good donor supply after allowing for the front
• have a crown area that is limited in size, or thinning rather than bald
• have realistic expectations about density at the crown

They tend to suit fewer people if you are young, your loss is still moving quickly or your donor supply is limited. Our guides on whether you are a good candidate and on transplants under 25 go into this further.

Alternatives and add-ons for the crown

Surgery is not the only way to deal with a thinning crown, and some people combine approaches.

• Medical treatment prescribed by a doctor may slow loss at the crown and help keep existing hair.
• Scalp micropigmentation can reduce the contrast between scalp and hair and create an impression of density. Our transplant vs SMP guide compares the two.
• A hair system covers the area without using donor hair at all.

If you are weighing crown surgery, ask the doctor to explain how many grafts the crown would use, what that leaves for the front, what happens if your crown keeps expanding, and what density you can realistically expect. If you want a clinic to assess you, ask for a callback.
