Alternatives for henna? Natural hair dye

[Dina2001]

My hair is very dark brown, but I want to light it 2 tones or so. I was wondering if there are any natural dyes in order for me to do that. I don't like henna because it gives a reddish/cooper undertone that is simply not for me. I wanna go with a light brown with warm honey undertones, if that makes sense. Though if there's a henna that doesn't leave that reddish tone, I'd try it. If that henna doesn't exist, then I guess I'll bleach my hair, even though that's scary.

Especially since I did a brazilian keratin treatment when I was 15 so...I mean, my hair has grown and I cut off all the damage that treatment did to my hair, but I'm still hesitant to bleach my hair because it may result in a disaster. Don't know if there's a safe way to bleach. If there is, I'd appreciate it if you let me know.

Thanks for reading.

Herbal dyes always darken. You cannot go lighter with henna or cassia.
Maybe honey lightening or lemon/camomile rinses but they are very subtle.

This is correct, there is no herbal dye that can lighten your hair. Honey and lemon/chamomile are very unreliable lighteners, and since your hair is so dark, attempts to lighten will almost for sure pull it redder if they're not strong enough to break down the red melanin in your hair.
