Review: Gentle on scalp . Good color - Lovely color . No harsh smell and gentle on my scalp . Only don’t live it longer than suggested as goes dark .
Review: Most natural, effective hair dye I have found! - Love Biokap natural hair dye so much, i am so pleased I found it! I discovered it earlier this year and I’m working my way through colours each month (on my greying roots - I’m 42) to find the lightest shade I can to suit my skin tone… I used to be naturally very dark brown, and dyed it even more so for decades….now I think my skin needs something slightly lighter… Works in ten mins - what a bonus, no excuse not to pop this on before a shower, no more waiting for 40 mins..! Sue at Biokap has been absolutely superb at answering my emails and providing advice, their customer service and desire to support is second to none. I moved from 4.0 and just tried 6.34 yesterday, I think I found my colour 🙌🏻 Hoping to keep dying only my roots, and grow out my slightly darker ends (it doesn’t look too pronounced, as I only ever added the Biokap colours to my roots) the warm tone of 6.34 is just what my face needed. ** this is the 5th colour I have tested with Biokap. My advice to anyone wanting to try their brilliant product is that these seem to come out much darker than the names suggest..! 4.0 was ultra close to black on me, but it’s name is Natural Brown 😱 I wasn’t happy when I first used it! Therefore, I would advise on starting light (choosing a high numbered box) then moving down the numbers to the darker shades (1.0 is black) as you can obviously put dark dye over light successfully, but light over permanent dark won’t lighten your hair. Hence me dying only the roots. The ends that have the darker colour from another brand are subtly fading, so this works for me. My goal is to make the most of the greys coming through, and to use them as natural streaks where they will have a warmer highlight… 👍🏻 Who knows…it might start a trend….life’s an experiment 🤗🤗
