Steven Ogden –
I tried the Slate Blue shade and it gave my grey hair a cool, icy finish. The color applied smoothly and didn’t feel harsh on my hair. After 10 washes, it’s still visible and my hair feels soft and hydrated. I love the metallic sheen and would definitely buy again.
Lily Vance –
The shade is exactly as described—metallic with a blue undertone. It’s easy to apply and my hair stayed vibrant through several washes. I didn’t notice any dryness or damage, which is great for my delicate strands.
Jan Marshall –
I’m new to semi-permanent dyes and this one worked perfectly. It’s easy to use, no peroxide needed, and my hair feels healthier after application. The color is subtle but striking, especially in natural light.
Lauren Nash –
The color is nice, but it faded a bit faster than expected. After 8 washes, it started to lose intensity. Still, the conditioning formula made my hair feel softer than with other dyes I’ve used.
