Japanese Study Validates Hasson & Wong Lateral Slit Technique

For the past ten years Hasson & Wong have been performing their lateral slit technique which we have claimed gives a more natural appearance to the transplanted hairs.

In the May 2006 edition of the Journal of Dermatologic Surgery a Japanese study entitled Orientation of Multi-Hair Follicular Units in Nonbald Men: Perpendicular Versus Parallel (Kuniyoshi Yagyu MD, Koki Hayashi MD, Stephen Chang MD), proved that the natural orientation of multi-hair follicular units is perpendicular to the direction of hair growth. The study was based on information accumulated from the study of 100 patients. This has been the principle behind the H&W Lateral Slit Technique. The placement of multi-hair follicular unit grafts into lateral slits will recreate this pattern seen in nature.

It is a rarity indeed to see a clinic's claims validated by a statistically significant study.
