Experience w/ organic or natural; at-home or salon hair dyes??

Hey everyone!

I'm looking for a gentler hair dying option.

I bleached my hair myself before a few times and it was alright. But then I was out of bleach and I tried a blonde box dye and it damaged my hair SO much. :mad:

I was looking into different things you can use for hair colouring. For example, Aveda Organic Colouring System (at hair salons) has very mixed reviews. People either love it or hate it. And btw, it is not organic and contains ammonia.

Please share your experiences with gentler hair dyes, whether they're at home kits or salon options; that contains little or no ammonia, etc.

Thanks!
