The small, fine hairs you might occasionally notice on your fingers are likely very fine vellus hairs, sometimes called "peach fuzz." Everyone has these hairs all over their body, and they're usually barely noticeable.
Reasons why you might notice these hairs more:
* Lighting: Bright or direct light can make these fine hairs more visible.
* New Hair Growth: If your hair is damaged or trimmed, hair follicles may get clogged, leading to a period of minimal hair growth.
* Magnification: Using a magnifying glass or taking a close-up photo can reveal these hairs.
Therefore, you cannot "grow" thicker or more noticeable hair on your fingers, as the hair follicles are not present to support that kind of growth.
