One of the advantages of human hair extensions is that these can be subject to the same physic-chemical treatments which are used on natural hair. Human hair extensions can be subjected to dyeing, colouring, cutting, styling, etc. Human hair extensions are mostly dyed in order that they may exactly match the colour of the person’s natural hair. However, care should be taken to see that the treatment is not too harsh – just as harsh chemicals damage your natural hair, human hair extensions may also be severely damaged, sometimes irreversibly, by these harsh chemicals. The best option would be to first try out any artificial treatment first on a small strand or section of the hair extension. If the results are satisfying without any side-effects, then the treatment can be carried out on the entire hair extension.
It must be remembered that human virgin hair extensions are no different in their reactions than natural hair. Hence, whatever treatment or process is chosen, including flat iron styling, should be safe for natural hair. Further, it is noticed that virgin Remy hair extensions are easier to treat than non-Remy hair extensions, since the latter have already been chemically treated and are hence weaker. The outer layer or the cuticle layer gives the hair extensions their shine and lustre; care should be taken to see that this is not adversely affected.
