Final answer:
Threading is recommended for removing the fine and soft vellus hair (peach fuzz) as it is gentle and doesn't affect the skin layers, making it suitable for sensitive skin.
Step-by-step explanation:
Threading is indeed recommended for removing vellus hair, also known as peach fuzz. This is true because threading is a gentle, non-invasive method to remove fine hair without affecting the delicate layers of the skin, making it suitable for people with sensitive skin. Compared to other hair removal techniques such as waxing, which can potentially remove a layer of skin along with the hair, threading is considered a safer and more precise option for vellus hair. The process involves a twisted cotton thread that is rolled over the skin, plucking the hair at the follicle level. It is especially popular for shaping eyebrows and removing unwanted facial hair.
