LOVE the colour but does fade quicker than expected
I have naturally dark blonde hair and tried to lighten it with a different hair dye to this one but it only went orangey. So for the first time ever I decided to go and dye it proper brown using this one. I wanted a dye that would take out the orangey coppery tones the old hair dye added in to my natural colour, and hoped for a cool brown, this one looked ideal from the picture and reviews.I was so happy with the colour afterwards it’s my favourite hair colour I’ve ever had and was everything I hoped taking out all the coppery and orangey by 100%. I put some extra hair oils on my hair before cool blow drying my hair to add some extra moisture and my hair was in good condition afterwards and so far seems to have remained in good condition. I didn’t wash my hair for 72 hours after dyeing it to try and help it, like how the hairdressers recommend.I’ve noticed each time I’ve washed my hair since dyeing it, my copper tones from the hair dye mistake I made before this one are now coming through more and more and after approximately 5 washes after I dyed it im feeling like it’s almost a 50/50 mix of this dye and the one before unfortunately. The third picture I’ve uploaded is how it looks now, in real life it is a bit more faded I think than the picture shows. I will try this again in about two months when my hairs had a rest.

Did what I needed
It’s turned out much darker in my hair, which is almost black, but I was trying to fix the strong red tint from my last dye, & it’s much better now!What I liked was that the colour seems even. My last dye made my roots much lighter & ends darker, which is not what I was going for. I put it on my roots first & then everywhere else for the last 5 minutes, & this has really sorted it out.I’m really happy with it, but let’s see if it fades as other reviewers have said.Also, it really stinks, my eyes were watering, for ventilated rooms only!

Fast shipping and excellent packaging. The Leatherman tool feels very premium and sturdy.
