    Love this product

    We use this product for 3 different hair types in our house. 2 bleached and 1 gray. Love how my hair feels after using it. Each hair type takes the color differently. Bleached course hair takes it bold, but fades faster, bleached fine, takes it a little less bold but it fades very slowly. Silver - does not take it bold, but it is clearly BLUE for the first few washes and then fades slowly.

    Very Blue

    Used this on my son's medium brown hair. It is super pigmented (more than other colors I've used) so be careful with skin and your bathroom. It lasted a long time in his hair but did fade.

    Thanks for the review, Gretchen! We're so glad to hear that you found the Cosmic Cobalt to be super pigmented - that deep blue color payoff is definitely one of the things our customers love about this shade! You're absolutely right about being careful with skin and bathroom surfaces - Cosmic Cobalt is definitely one of our most vibrant blues and can be quite intense, so we always recommend wearing gloves and protecting surfaces. We really appreciate you mentioning that it lasted a long time in your son's hair! It's totally normal for any semi-permanent color to fade over time, and it sounds like you got great longevity from it despite the eventual fading. Your heads up about the extra pigmentation compared to other colors will be really helpful for other customers to know what to expect when using Cosmic Cobalt. Thanks for sharing your experience!
