So I am wanting to henna my hair. As it is, I have a brown/reddish hair colour and I am thinking I'd like it a little more red. Want to stick to something natural, so am thinking henna. I know a few of you here have experience with it, so was wondering if you can link me to any good resources? Also, some experiences and thoughts, pros and cons, etc.. AND! Any before and after pictures would be cool! Thanks in advance!
