The trends observed may indicate that physicians are evolving their treatment strategies to implement newer antiviral medications. This may prove more efficacious for the treatment of cold sores.

Chemical relaxers are products marketed to straighten the hair and have been principally used by African Americans since the early twentieth century. They contain alkaline agents that break and reform hydrogen and disulfide bonds, leaving hair permanently straightened. Relaxers cause loss of tensile strength and increased fragility of the hair shaft that lead to increased risk of hair breakage and thinning. When used improperly, they can also cause local irritant contact dermatitis and chemical burns to the scalp and hairline that can potentially lead to a scarring alopecia. After interviewing several cosmetology educators in the field and reviewing the literature, we generated a list of ten pearls that all dermatologists should know about relaxers to provide professional guidance to their patients. Key points• Hair relaxers should only be applied by professional cosmetologists. • Base should be applied throughout the scalp, along the hairline, and around the ears to protect the skin from the corrosive effects of the alkaline chemical. • Ideally, hair should not be overprocessed, high-tension hair styles should be avoided the day of the relaxer, and permanent coloring should be delayed several weeks following relaxer use.
