No, washing your hair less doesn't inherently make it grow faster; hair growth is primarily genetic, but a clean, healthy scalp is crucial, so while over-washing can cause breakage, not washing enough leads to buildup, bacteria, and scalp issues that can hinder growth by creating a poor environment, so finding the right balance for your hair type is key for optimal length retention.
