Do Eyebrows Contain Extra Dormant Follicles That Can Be Stimulated to Produce Hair?

An electrologist removed a large amount of my brows without my permission. Internet electrologists say that areas such as the face contain a lot of dormant follicles that can be stimulated to produce new hair through things like hormones. Do the eyebrows contain dormant follicles that have never produced hair but can be stimulated through things like Latisse and Rogaine, and if so, about how many?

Latisse will not grow new brow hair in places where there are no follicles

Just like eyelashes, eyebrows contain follicles that are in the growth phase and follicles that are in the resting phase. There may be some evidence that Latisse (or Rogaine) can stimulate brow growth by stimulating the existing hairs to grow. But, it will not grow new brow hair in places where there are no follicles. At Chelsea Eye & Cosmetic Surgery Associates in NYC, we are working on a clinical study to see if Latisse will grow eyebrows. You can be involved in the study for free by contacting us at 212-727-3717.

Latisse can only work by stimulating growing eyelashes

The eyebrows do not contain dormant follicles that have never produced hair. There are approximately 100 to 150 eyelashes on each upper eyelid. The growth of eyelashes is cyclical, going through 3 stages: a growth phase, a transition phase, and a resting phase. At any given time, numerous hair follicles can be found in each of the different stages. The growth phase of an average eyelash hair is approximately 1 to 2 months. Latisse has been shown to increase the amount of time each eyelash hair remains in the growing phase. The application of Latisse has also been scientifically proven to increase the thickness of eyelash hair as well as the darkness of each hair. This is most likely due to an increased production of pigment within each hair follicle. Typically, within 4 months of application, Latisse can increase the length, thickness, and darkness of eyelashes and improve all the traits that are associated with greater prominence and overall attractiveness of the eyelashes.
