For The Claim

People often observe that stubble feels coarser and appears more noticeable after shaving, which can be interpreted as thicker or darker hair.
Hormonal changes during puberty can make hair thicker and darker around the time individuals start shaving, making it seem causally linked.

Against The Claim

Mayo Clinic and Cleveland Clinic state shaving does not change hair thickness, color, or growth rate; it only creates blunt tips that feel coarse.
Scientific American cites 1928 and 1970 studies showing no change in hair width, coarseness, or growth rate after shaving.
Healthline summarizes clinical evidence that shaving cuts dead hair at the skin surface and cannot alter follicles or regrowth characteristics.
Dermatologists quoted by major outlets explain the effect is a visual illusion from blunt-cut stubble, not actual thicker or darker hair.

Bottom Line

Strong medical and scientific evidence shows shaving does not biologically make hair grow back thicker or darker; the effect is an illusion from blunt regrowing stubble and coinciding hormonal changes. The common belief is understandable but not supported by data.
