if you want purple hair [SEP] i have silver hair and it needs a touch up once a week with a special shampoo i have tried other brands started with clairols shimmer lights too harsh and eventually ended up trying this brand due to all the great reviews i wish i could return it i much prefer the touch of silver brand for a few reasons smells better you do not need to hear gloves in order to use and does not leave your hair with the old lady syndrome of purple hair i leave it on for two minutes least amount recommended to get rid of brassiness and i always have a tint of purple in my hair after use it usually goes away after a couple of shampoos but that is not the point touch of silver is less expensive yes it is a smaller bottle and comes from overseas but it does not stain your hair or hands and does the job much better in my opinion
