Don’t be shy about explaining this to your clients! Recommendations for cuts should always work with the hair's natural growth pattern, be it in the crown area, nape area or front hairline. The nape area grows asymmetric, into a point--take advantage of this and incorporate the natural growth pattern. Doing so is vital to the success of your overall hair design. (e.g. fringe hairline lifts, cutting dry hair with no tension--the resulting fringe is symmetrical). When you work with nature and how the hair grows on it's own, your hairstyles become easy and organic, especially when it comes to styling and haircut maintenance. Considering the natural growth pattern is especially important as the haircut grows out.
