RT Journal Article SR Electronic T1 Technical Tip: Designing the Hairline Using the Prayer Mark JF International Society of Hair Restoration Surgery FD Publication of the International Society of Hair Restoration Surgery SP 49 OP 49 DO 10.33589/30.2.49 VO 30 IS 2 A1 Mohmand, Mohammad Humayun A1 Ahmad, Muhammad YR 2020 UL http://www.ISHRS-HTForum.org/content/30/2/49.abstract AB Designing a hairline is a difficult procedure that requires expertise. Although there are no specific rules about hairline placement, different factors play an important role. Forehead marks (prayer marks/bumps), which are caused by repeated contact of the forehead with the floor/prayer mat, are typically seen in Muslims. The hairline should always be marked above these marks, as daily practice will result in lack of hair growth in these areas.
