Thymosin Beta 4 Induces Hair Growth Via Stem Cell Migration And Differentiation

    Deborah Philp, Sharleen St‐Surin, HEE‐JAE CHA, Hye‐Sung Moon, Hynda K. Kleinman, Michael Elkin
    The study found that thymosin beta 4, a 43-amino-acid molecule, promoted hair growth in various rat and mice models, including a transgenic mouse overexpressing thymosin beta 4. The mechanism by which thymosin beta 4 facilitated hair growth involved the promotion of follicle stem cell growth, migration, differentiation, and protease production. These findings suggested that thymosin beta 4 played a significant role in hair growth through its influence on stem cell activities.

      Low-level laser therapy (LLLT) is debated for hair regrowth, with some users suggesting it should be combined with treatments like minoxidil and finasteride for effectiveness. Many users express skepticism about LLLT's efficacy and cost, emphasizing the need for the correct wavelength and quality devices.
