TLDR Tooth papilla cells can help regenerate hair follicles and grow hair.
A study from 2004 investigated the potential of tooth papilla cells to induce hair follicle regeneration and fiber growth. The researchers implanted different types of cells into amputated rat whisker follicles and observed the growth of external structures. They found that cultured tooth papilla cells from both humans and rats have the potential to induce hair follicle regeneration and fiber growth. The study suggests that tooth papilla cells could be used in hair regeneration therapies and tissue repair.
