Jessica Newman –
The color is vibrant and stays true to the Rockabilly Blue shade. My hair, which was previously lightened, looks healthy and well-conditioned after use. No harshness or dryness, which I appreciated.
Edward Ross –
Great for adding depth to my hair. The application was easy and the formula didn’t feel heavy. I noticed the color lasted longer than expected, especially on my pre-lightened strands.
Warren Baker –
I’ve tried several blue dyes before, and this one stands out for its rich tone and gentle formula. My hair feels softer after each use, and the color stays well for several weeks.
