That does make me think, though...I think that we have all the tools necessary to give someone natural hair of whatever color in 2025. It would not be quick or inexpensive, but it sounds like we do have the technology.

First, remove the existing hair:

https://en.wikipedia.org/wiki/Electrology

Electrology is the practice of electrical hair removal to permanently remove human hair from the body. Electrolysis is the actual process of removing hair using electricity.

In electrolysis, a qualified professional called an electrologist slides a hair-thin, solid metal probe into each hair follicle without puncturing the skin (when inserted properly). Electricity is delivered to the follicle through the probe, which causes localized damage to the areas that generate hairs, either through the formation of caustic sodium hydroxide (the galvanic method), overheating (thermolysis), or both (the blend method).

Take skin cells from the patient.

Genetically-edit to obtain hair of given color.

From that, grow new skin that's genetically compatible:

“We took human skin cells and reprogrammed them into stem cells, which can be turned into any type of cell in the body,” Dr Shafiee said.

University of Queensland researchers have been the first in the world to successfully grow fully functioning human skin in a laboratory.

The research team at UQ’s Frazer Institute used stem cells to create a replica of human skin, complete with blood vessels, capillaries, hair follicles, layers of tissue and immune cells.

Then transplant the hair follicles back into the patient.

With Follicular Unit Extraction or FUE harvesting, individual follicular units containing 1 to 4 hairs are removed under local anesthesia; this micro removal typically uses tiny punches of between 0.6mm and 1.0mm in diameter. The surgeon then uses very small micro blades or fine needles to puncture the sites for receiving the grafts, placing them in a predetermined density and pattern, and angling the wounds in a consistent fashion to promote a realistic hair pattern. The technicians generally do the final part of the procedure, inserting the individual grafts in place.

FUE takes place in a single long session or multiple small sessions. The FUE procedure is more time-consuming than strip surgery. An FUE surgery time varies according to the surgeons experience, speed in harvesting and patient characteristics. The procedure can take anywhere from a couple hours to extract 200 grafts for a scar correction to a surgery over two consecutive days for a megasession of 2,500 to 3,000 grafts.

Robotic hair restoration

Robotic hair restoration devices utilize cameras and robotic arms to assist the surgeon with the FUE procedure. In 2009, NeoGraft became the first robotic surgical device FDA approved for hair restoration.[8] The ARTAS System was FDA approved in 2011 for use in harvesting follicular units from brown-haired and black-haired men.[9]

So if you had the time, money, and determination, I imagine that you could probably get natural platinum blonde pubic hair if you were set on it.

In practice, my guess is that it's probably preferable to dye it.
