Cinnamic acid may help hair grow by activating oxytocin receptors.

Epimorphin, a protein, plays a key role in the development of hair follicles in human fetuses, but it doesn't help in maintaining the stem cell population of the follicular skin layer.

Hair in mammals likely evolved from glandular structures, not scales.

Nestin identifies specific progenitor cells in hair follicles that can become outer root sheath cells.

Nestin-expressing cells turn into a specific type of skin cell in hair follicles during development and in adults.

Nestin marks cells that can become a specific type of skin cell in hair follicles of both developing and adult mice.

ECM molecules are crucial for hair growth and development.

Hair growth is influenced by interactions between skin layers, growth factors, and hormones, but the exact mechanisms are not fully understood.

Children's hair grows in different types from before birth through puberty, with growth rates and characteristics varying by age, sex, and race.
