One of the most easiest and efficient ways to increase the hair density would be in using a hair extension. Hair Extensions Treatment uses a simple technique of lengthening one's hair by using natural human hair or artificial synthetic hair. Trichologist usually suggests opting for the natural hair as they can be used like a regular hair and can be dyed or permed. There are several types of hair extensions, the most common is the usage of clips in the extension. As the name suggests, clips are used for bonding the hair extensions to the hair. Usually done at the nape of the neck these clip-ons can be of varying lengths depending on the individual's preferences. However, they can be used only for a short duration and might have to be removed during sleeping. These are most preferred when the looks need to be there for a short period like a party or a ceremony. One of the other methods is the usage of tape in hair extensions. Hair is attached using a nonsticky adhesive tape to the hair clefts, and these can last for a few weeks. They can be even used as a natural hair and can be easily removed using a glue remover. Other methods use techniques like bonding and fusion and micro rings, but researchers have proved that these techniques cause more damage to the hair when used improperly. A trichologist would advise on hair extension only as a stop gap arrangement and never as a solution for treating hair loss or hair thinning.
