Facial & Body Hair Transplant

Another less commonly practiced source for donor grafts include facial and body hairs. This method is recommended for hair loss patients who have a low occipital hair density either naturally or due to previous surgeries.

In theory, hairs from any part of the body can be extracted using the FUE method and transplanted into any other part.

In order to avoid over harvestation of the occipital hairs, other sources of donor hairs such as facial and body hairs can be used as well.

After occipital hairs, facial hairs are a great candidate as they often have similar thickness and characteristics to the scalp hairs. Next, chest and arm hairs can be utilized as well. Finally thigh and leg hairs might be a good candidate if needed.

However there are several caveats that must be addressed. Body hairs often have contrasting characteristics to scalp hairs. These include: hair growth cycle, thickness, color, and hair type (curly vs straight).

In order to determine whether a patient is a suitable candidate for body hair transplant, these characteristics must be examined.

Facial and body hairs can also be used as donors if the patient has sufficient hairs in these regions.

Hair Cycle Discrepancy

 

Hairs grown in different body parts have a varying growth cycle to each other. This is evident in the fact that scalp hairs often have a growth phase which lasts for 2 – 6 years while facial hairs will grow for as long as one year. Body hairs however have the shortest growth cycle of 16 weeks which is also why scalp and facial hairs can grow long while body hairs will remain short.

With this in mind, what would happen if body hairs are transplanted into the scalp? Would they lead to a consistently shorter hair line with less volume?

Research in this area shows that the transplanted hairs are affected by their surrounding environment and their growth cycle changes to match the local hair follicles. This change however is unique for each hair type and recipient area. Facial hairs have a long hair cycle and they are a good candidate for hair restoration since they can add considerable volume to thinning areas. That may not be the case for body hairs however since their growth phase is significantly shorter. Experiments have shown that when donor hairs from the chest are transplanted onto the scalp, their growth cycle is affected and they tend to grow longer. This increase in growth is marginal however since the transplanted chest hairs only seem to grow a few centimeters longer (about 2 cm) than their normal length. This means that the transplanted body hairs will have a significantly shorter growth phase than scalp hairs which will result in shorter hairs with less coverage of thinning areas. As a result they should be used in combination with scalp or beard hair in order to add volume and result in patient satisfaction.

As for the hairline restoration itself, Dr. Nagai recommends using scalp hairs as donor since they give the most natural looking outcome and body and facial donors grafts can be used to add volume and thickness to the rest of the thinning areas.

Hair Thickness and Color

Body hairs often have a different color and thickness than scalp and facial hairs. This should be considered as well since unlike the hair cycle, the body hair`s thickness and color will not change after being transplanted into the scalp. Meaning that thicker body hairs must be used for this procedure to achieve satisfactory results.

As for the hair color, this depends on the patient`s individual case. If the color difference between the body and scalp hair is evident and distinct, post-surgery styling care such as using hair dyes or specific hair styles can be used.

Hair Type (Curly vs Straight)

Finally, hair type must be considered as well. Often, body hairs have a different hair type than scalp hairs. For example, patients with straight hairs might have curly body hair and vice versa. Much like the hair thickness, this characteristic of the transplanted hair will not change as well. This is only an issue for hair line restoration however, since hairs transplanted in other parts of the scalp will not be as visible and the difference in growth form is not noticeable.

Therefore, hair line transplanted grafts should preferably have a similar growth form (curly or straight) as the patient`s normal scalp hairs to achieve a more realistic result.

That being said, post-surgery styling care such as using hair iron might mitigate this problem.
