Alopecia (alopecia areata or alopecia universalis) is an autoimmune disorder sometimes triggered by stress; it may also be hereditary. The result is that, to varying degrees among the 5 million or so who are affected in the US, the body rejects its hair, including arm & leg, scalp, eyebrows and sometimes, eyelashes. This condition is often, but not always, permanent. Other causes of hair loss include chemotherapy, at least temporarily; sometimes emotional challenges result in compulsively pulling hair out from scalp or eyebrows (trichotillomania). Responses to hair loss can include the use of wigs (human hair wigs have become quite lovely as disguises) and makeup for missing eyebrows and eyelashes. Permanent makeup can be useful here, eliminating the chore of applying eyebrow pencil and eyeliner daily, as well as potential embarrassment at the gym or the pool. With their permission, I offer these illustrations of client experience with eyebrow tattoos. They are wearing human hair wigs, and still have at least some of their own eyelashes.
This client was 22 years old when she first came in. The first image is with drawn-on brows; the second is the way she looked after the first application had healed.
Here is how she looked immediately after the third application. I have tweaked the design just slightly in a later visit. If you look closely, you may see a few hairs at the center right brow edge. It is sometimes the case that the needling will stimulate hair growth.
This client was 17 years old; she came with her parents from North Carolina.
Alopecia can affect anyone. This fellow had a strong skin-irritation reaction to the process; the redness subsided in a couple of hours. As noted elsewhere, the color will lighten by about 30% as the surface skin wears away. I used a darker color for the second application, and his reaction became milder.
