No, the hair will not grow back thicker. The type of hair that is typically removed during a dermaplaning procedure is known as vellus hair, commonly referred to as "peach fuzz". This hair is fine and soft, and when it grows back after a dermaplaning session, it maintains its original characteristics. You can rest assured that dermaplaning will not cause your hair to grow back thicker or coarser - it will return as the same fine, soft vellus hair you had before. This makes dermaplaning a safe and effective method for exfoliating the skin and removing fine facial hair without altering the hair's texture or density.
