Difference between remy and non-remy hair
Firstly, we have to look through what is non-remy hair.
It is apparently the antonyms of remy hair, which will not be taken from one donor with greatest quality.
Non-remy hair is actually the left over hair, which should be thrown away when gathering the remy hair or creating hair style in salon. They are, in most cases is collected from the floors of factory, temples (that why we call temple hair) and salons then recycled to make a weft.
The hair cuticles are coped with various directions, which results the final products to tangle, shed and matte quite easily. The different length makes it harder to compile and compromise into specific range and the enormous amount of short hair (after doing haircut in salon) would wave the lack of longer hair products. Foremost, the hair quality strongly depends on its root – the people – and human are firmly not the same in hair texture, strength, color, quality, style… which would cause inconsistency of quality of a hair bundle due to it origins from varied donors.
Because sellers know this, they often dip the hair in a silicone coating to try to disguise the hair. This hair is often found in beauty supply stores and is less likely to be used for more than one installations.
