Density Density is the number of hairs per square inch. Keep the density medium to very light. The easiest and most convenient method is to use double-sided tape. These days this stuff is strong enough to hold in almost any situation, and the hairpiece can easily be removed, washed and re-applied with fresh tape. Daily liquid adhesives have no advantage over tapes, and the more permanent kinds of adhesives create the situation where parts of the scalp become impossible to clean for long periods of time.
Some men get over sized bases and attach the hairpieces to their real hair with sewn-in clips.
The line where the forehead ends and the hair starts is the area that gives away a bad hairpiece. If you can hold back your hair and remain undetected, your hairpiece is a good one. Regardless of which kind of base you have chosen, a see-through front is essential for this effect. Remember, people with real hair have very uneven hairlines. This isn t nearly as convincing as a see-through front but it s more robust.
