Natural or existing hair should generally be in good health, real hair extensions, when used properly, depend on attaching them to existing healthy hair. That means your natural hair should be healthy and ideally not subjected to too many chemical treatments. 

Excessive curling, bleaching, or coloring can weaken the shaft and damage the cuticle, or the outer layer. Hair extensions are a smart and simple solution for those who want to change their look and also those who are suffering from excessive hair loss.

This in turn causes the hair to break easily. Since lengthening puts stress on the hair and the follicles from which it grows, you should seek the advice of a counselor to assess the health of your hair. 

Fixed extensions may be a more suitable alternative to the related variant, as they cannot be used all the time and their position may vary.

Human hair extensions must only contain 100% human hair – check the guarantee, with the high demand for natural human hair, which is in limited supply, some manufacturers offer a “mix” of synthetic and 100% processed human hair.

But they still package the product as 100% human hair. While blended products are usually less expensive, the quality of different hair types varies. 

Synthetic hair reacts differently than human hair, and while this is invisible to the naked eye, it becomes especially apparent when treating extensions such as curling and straightening, when the fibers react differently and the fiber content can be damaged.
