Grown hairs are the result of the natural hair growth process, in which hair follicles produce new hair shafts that emerge from the skin's surface. For example, when hair on the scalp is left untrimmed, it grows longer, resulting in grown hairs.
Grown hairs are significant in various aspects. They are associated with personal appearance, hygiene, and cultural practices. Trimming or styling grown hairs helps maintain a desired look and prevents tangles or matting. Additionally, grown hairs provide insulation, protect against sun exposure, and enhance sensory perception.
