Many people aren't aware but Lush stock a range of henna hair dyes, which are used to colour the hair naturally without any nasties! I picked up Caca Rouge after googling lots of pictures - it seemed to be pretty close to the colour I normally dye it so thought I didn't have much to lose.
The bar was surprisingly large and the lovely sales assistant said that I'd only need about half of it for one application but silly me used far too much hot water when mixing it all together so had to use the remaining blocks to try and salvage the mixture...typical! Now, I'm not going to lie to you, this is MESSY, but I loved it.
You mix the henna with hot water in a heat-proof bowl over a saucepan of hot water. The henna does take a while to melt down completely but I just left it to it and just stirred every so often. Henna is renowned for having a strong smell and Lush do do their best to cover this up - when in the bar, it smells gorgeous, the cocoa butter is definitely the predominant smell, but then when it's all mixed up, there it definitely had an earthy smell (strong, but not unpleasant!).
Now for the fun bit! I basically just slapped this on my head - it's basically like smothering mud all over your hair (and definitely felt like shampooing dried up mud out of my hair!). On reflection, I probably should have been a bit more methodical but it seemed to work at the time!
Lush suggest that you wrap your hair in clingfilm for stronger red tones (so that's what I did) but you can also just leave it as it is to oxidise, if you want a more natural, browner result. After leaving on for three hours, I was really impressed with the colour, I couldn't put my finger on what it was but I got so many compliments on my hair colour for the next few days. I think it added richer tones and shine to my already red hair.
I think the results would be much more striking on someone who wasn't already a redhead but I was genuinely really pleased with the results, although Lush say that this is more of a "treatment" because of the moisturising ingredients, my hair felt in the same condition as if I'd used a chemical dye.
Have you or would you use a henna dye? Lush also do a reddy brown henna and a lovely black henna, so there's something for most!
