Dermaplane and Hair Growth

No, dermaplaning (using a blade to remove superficial skin cells and hair on the surface of the skin) will not cause increased hair growth. This procedure does not at all effect the hair cycle, which is regulated by cells deep within each hair follicle. Hair that has been exposed to "the elements" (ultraviolet rays from the sun), chemicals in our skincare products, etc. may seem thinner/less coarse that that comprising the "stubble" that you notice soon after shaving or dermaplaning. However, the individual hairs are still growing at the same rate and thickness as they would have before you shaved them since, again, you have not affected the cells deeper within the follicle that dictate the length of the hair cycle and the thickness of individual hairs.

So, you can rest assured that dermaplaning, as well as shaving at home, will not cause you to be more hairy in the long run.

To the best of my knowledge there is no study supporting this but there may be anecdotal evidence to support this finding. For example, it is known that nail biters nails grow faster than individuals who do not bite their nails. However, we do not necessarily know that shaving absolutely increases the growth of facial hair of if it becomes more noticeable because the hair becomes thicker or more dense.
