Official title

Fractional Photothermolysis for the Induction of Hair Follicles Via Skin Rejuvenation

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study is being done to evaluate the effects of fractional photothermolysis (known as laser resurfacing) using fractional laser for the induction of hair follicles via skin rejuvenation in subjects with scalp alopecia (specifically, alopecia on the superior forehead at the frontal hairline). Fractional photothermolysis has been shown to be effective in promoting hair growth. The investigators will study 50 subjects who will be treated 6-10 times at 2-4 week intervals. Each participant will have half of their head treated with a laser, either Fraxel DUAL 1550 or Halo by Sciton, and the other half of their head will be left untreated as a control. Half of the individuals will randomly be assigned to the group to be treated with Fraxel DUAL 1550, and the other half will be treated with Halo by Sciton. Visual observation and digital, photographic, non-invasive imaging will be used to compare the treated and untreated area to assess for differences in hair follicle stimulation rates, number and density of hairs. As noted above, the types of lasers we plan to use include the non-ablative fractional laser settings for the Fraxel DUAL 1550 and Halo by Sciton. A fractional laser is a laser that directs an intense burst of laser energy on the skin. The treatment deposits heat deep into the dermis to tighten skin and stimulate collagen remodeling. The necrotic (death of cells or tissue) injury heals rapidly and adverse effects are few. Laser resurfacing is commonly used for rejuvenation of the skin to improve quality, tone, and texture.
