I've been using henna for many years now. I love the deep reds I get from Rajasthani henna. I used to use it with a bit of indigo but the last half year I have used it on it's own and still got a deep red on my grays. I've now decided the reddish hair just isn't suiting my face and I want to go back to my natural gray (which is a salt and pepper with dark brown & gray) Before I do that I want to turn my hair colour as brown as I can get it. That way it will blend in a little better with my dark brown coming in and I won't have 3 colours in my hair. I have amla, indigo , & henna but am not sure what combination to mix up (50% henna, 25% indigo, 25% amla?) and how long to leave it on my hair that's already had henna on it (I normally would go 4 hours doing roots only). Maybe this isn't the route to take at all and maybe I should just let my gray hair grow in with the red/brown. It IS lighter than my natural brown that's for sure. I plan to dye my hair part (I have medium length hair) for a few months in the growing out process.
Any ideas ? Thanks. I've checked out ideas from ladies who have gone gray using chemical hair dye but it's a different situation with henna.
