Hair restoration typically involves transplanting follicles from the back and sides of the scalp, areas resistant to pattern baldness. This procedure relocates healthy donor follicles to balding areas. For individuals with extensive hair loss, however, the supply of available scalp hair can be severely limited. This scarcity raises the question of whether non-scalp follicles, specifically pubic hair, can serve as a viable alternative source for transplantation.
Technical Feasibility of Harvesting and Graft Survival
The fundamental biological structure of a hair follicle is consistent across the body, meaning pubic hair follicles contain the necessary cellular components to survive transplantation. When using pubic hair, the Follicular Unit Extraction (FUE) method is the standard harvesting technique. FUE extracts individual follicular units one by one, which is better suited for the unique angle and solitary grouping of body hair compared to the strip-harvesting method (FUT).
Extracting follicles from the pubic region requires specialized precision due to the skin’s sensitivity and the acute angle at which the hair emerges. Surgeons must use specialized micro-punches to carefully remove the follicle while minimizing the risk of transection. Transection is the physical damage to the follicular unit during extraction. A higher rate of graft transection is sometimes reported in body hair extractions, including the pubic area, compared to the more predictable scalp skin.
Once extracted, pubic hair grafts must maintain viability before implantation into the recipient site, similar to any other transplanted follicle. Standard FUE graft survival rates for scalp hair range between 85% and 97% when meticulous handling protocols are followed. Although long-term survival data for pubic hair grafts is limited, the follicles are biologically capable of establishing a blood supply and growing in their new location. Success depends on the surgeon’s skill in careful FUE extraction from the challenging donor site and the proper handling and storage of the grafts outside the body.
Growth Cycle and Aesthetic Differences from Scalp Hair
The primary difference between pubic hair and scalp hair is the growth cycle, which significantly impacts the final aesthetic result after transplantation. Hair growth occurs in three main phases: anagen (growth), catagen (transition), and telogen (resting). For scalp hair, the anagen phase is long, lasting between three and seven years, allowing the hair to grow to a substantial length.
In contrast, pubic hair has a significantly shorter anagen phase, typically lasting only a few months. This short growth phase dictates that transplanted pubic hair will not achieve the long length of normal scalp hair, instead growing to a terminal length and then shedding. The shorter growth cycle means the transplanted hair will require more frequent trimming to blend with the surrounding scalp hair.
Aesthetic differences further complicate the use of pubic hair for the scalp. Pubic hair is often thicker in diameter and more coarse in texture than the fine hair typically found at the scalp’s hairline. The curl pattern is often tighter and more pronounced, and the color can sometimes differ from the native scalp hair. These intrinsic characteristics remain largely unchanged after transplantation, resulting in a noticeable textural mismatch if not placed strategically.
Specific Applications and Resulting Density
The use of pubic hair grafts is classified under Body Hair Transplantation (BHT) and is considered a method of last resort. This option is typically presented only to patients who have severely depleted scalp donor hair from previous procedures or who have extensive hair loss. The limitations of the growth cycle and texture prevent it from being the first choice for primary coverage or hairline creation.
The most common application for pubic hair grafts is to supplement density in areas that already have existing hair, a process often called “bulking up.” The coarser caliber of the pubic hair can create the illusion of greater volume when intermixed with thinner scalp hair, helping to fill the mid-scalp and crown regions. Pubic hair is also used for scar camouflage, particularly to conceal linear scars from older strip-harvesting (FUT) procedures.
The resulting density achievable with pubic hair is inherently limited due to the natural characteristics of the follicle. Unlike scalp hair, which typically grows in follicular units of one to five hairs, pubic hair follicles usually contain only a single hair. This sparse grouping means that a larger number of individual grafts must be transplanted to achieve the same coverage that a smaller number of multi-hair scalp grafts would provide. Ultimately, pubic hair serves as a valuable supplementary donor source when traditional scalp options are exhausted, offering modest gains in coverage and density rather than a complete restoration.
