The alternatives to shopping in person are mail order shopping by catalog or on-line shopping. In either case we need to be clear about return policies. Some states do not allow wigs to be returned as a matter of health concerns. Sizing can be a cause for returns because the typical male head is larger than the typical female head. Most wigs are offered in one size with adjustments in the cap for sizing.
Color also can be a cause for returns.
The color that appears on your monitor may be quite different than the actual wig. Most monitors are not calibrated for color and, even if they were, most websites do not send out colors which are consistent from site to site. Some software such as Photoshop and Paint Shop Pro have utlities which allow you to adjust the gamma of your monitor. There is a new web utility available for ecolor which will help in adjusting your monitor. This is especially helpful in viewing colors that subscribe to the ecolor standard.
