Tim Bond –
I tried Yellow Colour 5.66 for the first time and it gave my hair a bright, natural yellow tone. It’s easy to apply and doesn’t feel heavy. My hair stayed vibrant for about 4 weeks before fading slightly. I’d recommend it to anyone looking for a warm, subtle pop of color.

The color is true to the sample. It adds a nice warmth without being too bold. I used it on my mid-lengths and it blended well with my natural hair. It’s gentle on my hair and didn’t cause dryness.
