Colora Henna works wonders for your hair, particularly if it feels dull and lifeless. Natural Henna adds body and bounce and offers a choice of rich but subtle color changes. Colora brightens and highlights your hair, leaving it gleaming and elegant. For external use only. This product must not be used for dyeing eyelashes or eyebrows. Because Colora is completely natural, without any synthetic additives, results will vary for each individual, so, if you are using Colora for the first time, it is recommended that you first apply a small quantity on an inconspicuous strand of hair prior to full scale application.
