If you have red hair this is the product to have in your shower. This helps keep the red vibran until your next appointment. The effectiveness is amazing but the process is messy. You have to leave the product on your hair for 20 min and you can get stain easily. You need to wear gloves when you apply the product and when you wash your hair. You also need to be carefull and rince right away is some of it gets on the walls of your shower.
$30 for 250ml but worth it, you can delay your next appointment to your hair dresser for a good 2-3 weeks.
