My niece loved it!
My niece had been begging to color her hair for a while and the cosmic cobalt was perfect! It gave her the color she was itching for without sticking around for ages or damaging her hair

Longest Lasting Vibrant yet!
I have Magenta Majesty, Cosmic Cobalt, Royal Plum, & Vibrant Teal in my hair and most colors are pretty faded but Cosmic Cobalt looks as good as the day I put it in!
Also does great on darker hair. This’ll be one of my go-to colors for sure.

Hi Jessica! We're absolutely thrilled that Cosmic Cobalt is holding up so beautifully in your multi-color setup - especially when you've got Magenta Majesty, Royal Plum, and Vibrant Teal going on too! The fact that it's looking as vibrant as day one while your other colors have faded is seriously impressive, and we love that you're making it a go-to shade. It sounds like you've got an amazing colorful collection happening, and we're so happy Cosmic Cobalt is proving to be the long-lasting powerhouse in your rotation. Thanks for sharing this - it's awesome to hear how it's performing on darker hair and we're thrilled you're loving it!

Out of this world!
Cosmic Blue Masking Conditioner on completely Grey hair- awesome! I previously used Teal but it doesn't seem to last too long ( I only wash my dry hair once a week) We'll see how long this lasts but wow! 20 minutes, first time application.

Hi Christine! We absolutely LOVE this - "out of this world" is exactly the vibe we're going for with Cosmic Cobalt! It sounds like you're getting some seriously stunning results on your grey hair, and we're so thrilled that you're seeing that gorgeous blue come through on your first application. Thanks so much for sharing your comparison with the Teal too - it's super helpful to hear how different shades are working for you and your hair care routine. We're excited to hear how the Cosmic Cobalt holds up for you over time, and we really appreciate you giving it a try! Keep rocking that cosmic blue look!
