Fractional Nonablative Laser and Topical Minoxidil For Alopecia Areata

Four of eight patients with alopecia areata (AA) experienced 30 percent to 100 percent hair regrowth following treatment with a fractional nonablative laser and topical minoxidil (5 percent). Researchers Yuanhong Li, MD, PhD, et al, from the department of dermatology, Hospital of China Medical University in Shenyang, China, performed 10 laser treatments every two weeks (10 to 15 mJ of energy with a total intensity of 300 spots/cm2). Topical minoxidil tincture was applied immediately following each laser treatment and used twice daily throughout the treatment regimen.

PRP Increases Hair Density In Vivo

PRP Increases Hair Density In Vivo

Platelet-rich plasma has been touted as a potential treatment for alopecia and thinning hair. Now a new in vivo study, “Promotional Effect of Platelet-Rich Plasma on Hair Follicle Reconstitution in vivo” (Dermatologic Surgery, December 2013), reveals that a 10% concentration of PRP, when added to cultured epidermal and dermal papilla cells, increases hair density.

Hair Regeneration Method Induces New Human Hair Growth

Hair Regeneration Method Induces New Human Hair Growth

Researchers at Columbia University Medical Center (CUMC) have devised a hair restoration method that can generate new human hair growth, rather than simply redistribute hair from one part of the scalp to another. The approach could significantly expand the use of hair transplantation to women with hair loss, who tend to have insufficient donor hair, as well as to men in early stages of baldness. The study was published online edition of the Proceedings of the National Academy of Sciences (October 21, 2013).
