Photo Epilation with Intense Pulsed Light for Thinning of Anterior Hairline after Hairline Correction Surgery in East Asians

Background Thin hairs are critical to achieve natural result in female hairline correction surgery. However, there are few studies on the usefulness of hair thinning by intense pulsed light (IPL) after hairline correction surgery in East Asian females. Methods Hair thinning using IPL was performed in 54 women who had complained about thick hairs along the frontal hairline after hairline correction surgery. Patient mean age was 31.2 years old and patients were an average of 2.1 years post-hairline correction surgery. Initial treatment used 10 J, while second and third sessions were conducted with 10 to 15 J according to responsiveness to treatment. Results Mean thickness of individual hairs assessed before the procedure was $78.86{\mu}m$. The mean number of procedures was 1.6 per patient. Forty of 54 subjects (74%) achieved satisfactory hair thinning with only one procedure from 78.01 to $66.14{\mu}m$ after treatment. The measured thickness was $66.43{\mu}m$ at the end of the first year in patients who were satisfied after one procedure. Thirteen cases achieved satisfactory hair thinning after two sessions. Mean thickness was $74.44{\mu}m$ and $67.51{\mu}m$, before and after the second session. One case required a third session with 15J, thinning from 89.00 to $66.50{\mu}m$. Conclusions Hair thinning by IPL is a very useful method to provide a natural look after hairline correction surgery in East Asians, who have naturally thick hair.
