Dyeing hair extensions
We all know that 100% human hair extensions can be dyed. The perfect hair type for coloring is the virgin hair extension also called virgin Remy hair extensions. This type of hair would have never been chemically-processed before you receive them and hence should be ideal for dyeing. Coloring of virgin hair extensions is much like doing them for natural hair and a lot of care must be taken to protect them from harsh chemical agents. Most other types of hair, especially synthetic hair, are unsuitable for dyeing as they tend to become really weak due to exposure to chemicals. Dyeing them will irreversibly damage your hair extensions. Again, strand testing is the best method to prevent damage from dyeing.
