While it's understandable that you would want to utilize body hair for an eyebrow transplant, especially if you have concerns about the density of your scalp hair, there are a few factors to consider. 1. Hair Characteristics: The characteristics of body hair and scalp hair are different. Body hair is typically thinner and grows slower compared to scalp hair. Therefore, using body hair for an eyebrow transplant may not yield the same results. 2. Surgical Technique: The technique used to harvest body hair is different and can be more challenging than that used to harvest scalp hair. This might be the reason why you're finding it hard to locate a surgeon who offers this procedure. 3. Growth Pattern: The direction and pattern of growth are different between scalp hair and body hair. This could affect the aesthetic outcome of the transplant. 4. Survival Rate: The survival rate of body hair when transplanted to the eyebrows can be lower than that of scalp hair. 5. Graft Production: Body hair typically provides fewer grafts than scalp hair, which could limit the density you're able to achieve with the transplant. However, it's important to discuss these concerns with a hair transplant specialist. They can provide personalized advice based on your specific circumstances and may be able to suggest alternative solutions to meet your needs.
