Because I was born in Russia, people tend to assume that this explains my strong preference for Russian-sourced hair. The reason is, however, quite different. In order to explain, it might be sensible to talk about some of the sources of hair commonly used in extensions and to look more closely at their relative pros and cons.
Synthetic hair, in other words, man-made fibres intended to look like human hair, has been widely used in the manufacture of hair extensions, particularly in low quality, off-the-shelf products. Its virtue is that it’s cheap – but that’s about it. When seen close-to, it’s apparent that it doesn’t match your natural hair, nor does it move in the same way – compared with real hair extensions, it screams “fake”. Synthetic hair works fine for theatrical applications but it fails to reach the standards that most people would demand for normal use.
