ATODHL is used to assist the design of a hair line during hair transplantation. Align the vertical center line with the nose between the eyes. Align also the horizontal zero line with the eyebrows or the glabella and at the same time check the horizontal alignment with the lateral technique. Pull straps backwards and lock in position. Mark hair line points along the vertical scales. Join the points.

The product is clean but not sterile. It is intended for a limited reuse as long as it is kept clean.
