When a prosthesis requires facial hair, anaplastologist will often use real hair. For brows especially, we try to use a sample of the patient’s hair, when available, or a donor’s. The best donor hair has a variety of thicknesses and colors in each sample allowing it to create the appropriate variability of color and texture we see in brows and lashes. For thick lashes or mustaches, we will often buy hair (real or synthetic) for application. Some anaplastologists may be or work with a wigmaker or hair specialist to make custom mustaches or wigs for patients that require them.
