You are thus required to have some existing hair for the technique to work. The same technique can be used on men and women, and is most commonly used for male and female pattern baldness. In some add-on techniques, hair can be taped to the skin with adhesives, or can be woven in with tunnel grafts. The cost for add-ons is quite variable and often depends on reliability of the company and quality of the product. Often, regular follow-up for maintenance is necessary.
Hair extensions work on the same principle, as do hair prosthesis.
Wigs and toupees are more traditional options, and can also be of real or synthetic hair. Fill-in sprays are less popular alternatives, and are really just coloring the scalp and adding bulk which sticks to already existing hair to make it look thicker. Target Users Anybody with hair loss, though toupees work best for those with vertex and front hair loss. Full wigs work for anybody. Cost Quite variable depending on the quality and service of the product and company.
