Jonathan Reveals Hair Loss: Can Body Hair Transplants Work?

Entertainer Jonathan revealed on MBC’s “Radio Star” that he shaved his head due to severe hair loss. The 26-year-old entertainer stated he is considering a body hair transplant to address the condition, highlighting a growing trend where 37% of hair loss patients in South Korea are now in their 20s and 30s.

Why did Jonathan shave his head?

During an appearance on “Radio Star” on the 10th, Jonathan confessed that hair loss began at a young age. He told the program he decided to shave his head because the hair loss had become too visible.

Host Kim Gura noted that hair loss is uncommon at Jonathan’s age. Jonathan responded that many young people are starting to experience the condition early.

Did You Know? According to the Health Insurance Review and Assessment Service, 241,217 people received health insurance coverage for hair loss in 2024, though the total affected population in South Korea is estimated at 10 million.

Can body hair be used for transplants?

Jonathan mentioned that his body hair is extensive, describing it as a “mountain range,” and noted he heard body hair could be transplanted. Medical data indicates this is possible but not a standard procedure.

Scalp hair typically grows in clusters of one to four strands per follicle. Body hair generally produces only one strand per follicle, which can lead to lower density after a transplant.

Beard hair is considered more suitable than chest hair because it is 1.5 to 2 times thicker than scalp hair and grows continuously. However, differences in growth direction and texture may create a visible contrast with original scalp hair.

Expert Insight: Samantha Carter notes that for patients with M-shaped receding hairlines, medication alone only shows noticeable improvement in 10% to 20% of cases. This creates a significant reliance on surgical transplants when medication only slows progression rather than restoring lost hair.

Why is hair loss increasing among young adults?

Medical sources attribute the rise in youth hair loss to genetics, chronic stress, obesity, and diabetes. Nutritional imbalances caused by a diet heavy in delivery foods also contribute to deteriorating scalp health.

Data from the Health Insurance Review and Assessment Service shows that 30-year-olds make up 21% (50,565 people) and 20-year-olds make up 16% (38,105 people) of insured patients. This combined 37% indicates that over one-third of patients are young adults.

Androgenetic alopecia, or male-pattern baldness, is estimated to affect 15% to 25% of all men. It is a progressive disease driven by male hormones.

What are the treatment options for hair loss?

Medication is cited as the most effective way to stop the progression of hair loss. While drugs can slow the process, they rarely regrow thick hair in areas where it is already gone.

For M-shaped receding lines, such as the one described by Jonathan, a combination of medication and hair transplantation is often required. Standard transplants usually involve moving healthy follicles from the back of the head to the thinning areas.

If the back of the head lacks sufficient follicles, surgeons may consider body hair as a secondary option.
