Renbow Crazy Color - Silver, Marshmallow, Graphite, Platinum, Lilac, Burgundy, Tinte, Candy Floss, & MoreEach bottle contains 100ml of thick conditioning color which makes it great for using with special dyeing effects and its price is not expensive to try a few colours at once! It is recommended to apply the dye to pre-lightened or bleached hair. If applying to natural hair, a Crazy Color dye in a darker shade may offer a great tint to your hair. Semi-permanent hair dye can last approx. 4-8 washes, this can vary dependant on hair type. Renbow Crazy Hair Color (non-permanent) does not contain bleach (peroxide), the bottle says to leave it on for 30 minutes, although every 2 weeks when you dye your hair, you leave it on for 4-5 hours straight then wrap up your hair with clingfilm. This does not damage your hair, and you shoul use a conditioner afterwards to ensure that your hair is soft & well-nourished.
