I just bought this tonight; [Link](Mouse over link to see full location)
I've never dyed my hair before, and was against it for years. But for about a year now I've been wanting to dye my hair a more richer/auburn red color.
Naturally, I have red hair. It looks brown in the shade, but orange in the sun; [Link](Mouse over link to see full location)
I was going to keep then henna in for about an hour in a half, maybe two hours to get the richer/auburn-y color I want. But I wanted to ask others for their opinion.
Also, is this permanent? Or will it eventually wash out after a few months?
In reference to the length of time you should leave it, I recommend that you follow the instructions. The dye itself is described as a chestnut, and so will be a dark brown rather than the auburn you want. The problem with some types of henna hair dyes is that leaving it in for too long can make your hair orange. As in bright orange (like the fruit). I don't know if this is with all hair dye, or just some henna ones that my friends have tried, but its definitely a possibility.
My advice to you is to leave it in for the recommended time, and see what colour you get. The chances are that you probably won't get a henna dye that gives you auburn, as most natural authentic henna usually is just to dye your hair a dark brown-black, or orange if that's what you want.
So use it for the recommended time, and if it doesn't work, try and find a new one that does. If you have a LUSH store near you, you could ask as their staff are usually very friendly and knowledgeable. Alternatively, you could e-mail them before you buy the product, asking if they have any advice.
