The Science Behind Hair Transplant Surgery


Hair transplant surgery is a highly specialized field that involves the removal of hair follicles from one part of the body and transplanting them to another. Eyebrow transplant procedures, for example, use follicular unit transplantation (FUT) or follicular unit extraction (FUE) techniques to restore eyebrows that have thinned or been lost due to genetics or aging. The science behind hair transplant surgery has evolved over the years, making it possible to achieve natural-looking results with minimal scarring. For example, DHI hair transplant uses direct hair implantation to transplant individual follicular units, resulting in thicker and fuller hair growth. The science behind hair transplant surgery is based on the principle that hair follicles taken from the back and sides of the head are more resistant to genetic hair loss, and are therefore more likely to grow when transplanted to another part of the scalp.

The role of hair follicle density in hair transplant surgery

The density of hair follicles in a given area of the scalp can impact the overall appearance and outcome of the transplant. Patients with high hair follicle density typically have a fuller, more natural-looking result after the transplant, while those with low density may require additional procedures or touch-ups to achieve the desired outcome. This is why hair transplant surgeons must assess hair follicle density and use that information to guide their surgical planning. For example, if a patient has low hair follicle density, the surgeon may choose to transplant hair follicles closer together to create a more robust and natural appearance. In contrast, if the density is high, the surgeon may be able to space out the transplanted follicles, creating a more gradual and natural-looking result.

How do hair transplant surgeons determine the ideal hairline?

Hair transplant surgeons take several factors into consideration when determining the ideal hairline for each patient. Firstly, the surgeon will examine the patient’s face shape and existing hairline to understand what will look natural for their individual features. The patient’s age and the amount of hair loss they have experienced are also taken into consideration. For example, a younger patient may require a more dramatic hairline than an older patient. The surgeon may also use computer simulations to show the patient what the hairline will look like post-surgery. In addition to these factors, the surgeon will also consider the patient’s personal preferences and goals for their hair transplant. The patient needs to communicate their desired outcome with the surgeon so that they can work together to create the ideal hairline.
