NDH - Non Detectable Hairline
NDH stands for "non-detectable hairline," and is used to reference hair loss solutions that create a natural look. Rather than using the "hair plugs" solutions of the past, NDH technology allows a more natural, delicate hairline. This means that many men and women who have had to settle for lesser solutions in the past now can receive a near-perfect solution through NDH.
Now, of course, a solution that provides this level of excellence can cost a hefty amount. Most of us don't have thousands upon thousands of dollars to spent on hair systems. Ideally, you can get a solution that give you the best results available without spending your entire fortune on it.
There are many systems on the market that allow you to do just that. You can find many hair replacement methods that provide you with a NHD so no one will know that you have any kind of hair system in place. Those systems that have NDH also generally have the most naturally-looking hair in the system.
Whether you choose synthetic hair or real hair, you want to make sure that the texture, color and density match that of your natural hair. If the hair system you choose is different than your real hair then everyone will know you've had some hair work done. The right match means that you'll have the most natural-looking head of hair possible.
