Does your hair need to be clean to use the HairMax LaserComb?
We do recommend that you use the HairMax LaserComb on a clean scalp so that the laser can effectively improve the appearance of your hair without being hindered by oils, dandruff, etc. The reason for this is to prevent product buildup from blocking the laser light. However, you can also address this by cleaning your LaserComb with a damp cloth before and after each use.
