Summary and Key Features Laser hair removal (LHR) is the most commonly requested cosmetic procedure in the world. The ideal candidate for LHR is fair skinned with dark terminal hair; however, LHR can currently be successfully performed in all skin…
Summary and Key Features Advances in pigment-specific lasers have allowed for the safe and effective treatment of various benign pigmented lesions and tattoos. Picosecond (PS) lasers are the newest additions with current studies suggesting a superior efficacy and safety profile…
Summary and Key Features Vascular lesions are among the most common indications for laser treatment. Treatment relies on the theory of selective photothermolysis and aims to confine thermal injury to targeted vessels. Pulsed dye laser (PDL) is the treatment of…
Summary and Key Features Laser is an acronym that stands for Light Amplification by Stimulated Emission of Radiation. Laser light is a concentrated beam of electromagnetic radiation that travels at a single wavelength. The therapeutic value of a laser rests…
Key points Using clustered, regularly interspaced, short palindromic repeats-CRISPR associated protein 9, hair follicles with high steroid type II 5α-reductase enzyme activity can be genetically altered into follicles with suppressed SRD5A2 enzyme activity, theoretically allowing hair follicles to grow new…
Key points Topical prostaglandin analogs may increase vellus and terminal hair density and stimulate hair follicle activity. Janus kinase inhibitors demonstrate great success in the treatment of alopecia areata, with potential for androgenetic alopecia. Therapies targeting growth-factor regulation offer innovative…
Key points Several laser and light-based therapies, including low-level laser/light therapy, excimer laser, monochromatic excimer light, narrowband ultraviolet B phototherapy, and fractional laser, have been studied for the treatment of androgenetic alopecia. Most research has focused on low-level laser/light therapy,…
Key points Hair transplantation consistently creates natural-appearing hair for men and women with hair loss. Indications for hair transplantation include male and female pattern hair loss, inactive inflammatory scalp dermatoses, and reconstruction of hairlines lost to trauma or surgery. Realistic…
Key points Stem cells are a potential therapeutic option for the treatment of androgenetic alopecia and other forms of hair loss. However, serious adverse events have been previously reported from the use of stem cells for non dermatologic applications. As…
Key points Androgenetic alopecia is the most common form of hair loss and is characterized by progressive reduction and miniaturization of terminal hair follicles on the scalp. Although androgenetic alopecia is benign in nature and often considered part of the…
