research Normal Head-Hair Length Is Correlated With Its Diameter
Hair length and thickness are related, with thickness peaking at about a quarter of the hair's maximum length.
research Resting No More: Redefining Telogen, the Maintenance Stage of the Hair Growth Cycle
The telogen phase of hair growth is active and important for preparing hair follicles for regeneration, not just a resting stage.
research Trans-Species Hair Growth Induction by Human Hair Follicle Dermal Papillae
Human hair follicle cells can grow hair when put into mouse skin if they stay in contact with mouse cells.
research Changing the Shape of Hair with Keratin Peptides
Keratin peptides can change hair shape gently without harsh chemicals.
research Critical Study of Hair Growth Analysis with Computer-Assisted Methods
The Trichoscan system was found to be inaccurate for measuring hair growth, needing better software to be useful.
