Does your hair change every 7 years?

Yes, it's a common saying that hair changes every 7 years because a single hair's life cycle can last up to seven years, but it's more of a gradual shift influenced by aging, hormones, and genetics, leading to changes in thickness, color, and texture, with follicles slowing down and producing finer, lighter, or fewer hairs over time.
