Dying over Colora Henna Natural?
I recently dyed my hair with Colora Henna, natural. It didn't leave any color, as expected, and definitely helped add moisture, volume, and shine to my hair. I usually re-dye my hair in summer time, but I've been looking online and apparently if the henna isn't "pure," dying over it can cause green hair or damaged hair. I understand that henna coats your hair and all, but it's going to be quite difficult to tell when it grows out of my hair seeing as there is no color and I'm not planning to cut off my hair anytime soon.
Has anyone had any experiences in dying over Colora Henna Natural Color?
Please don't answer if you used another brand, or have had no experience.

Colora is likely to have henna extract but no actual henna, so it's not really a henna dye product. I believe that it does NOT contain metallic salts, which are what causes reactions with peroxide or ammonia containing dyes. Pure henna doesn't not react with chemical dyes, but then again there's likely no real henna in Colora. To know, test hair from your hairbrush first.
Two things. Henna does not coat your hair. Henna binds on a molecular level with your hair. Metallic salts do "coat" your hair, meaning they just build up on the outside of the hair shaft, and they are the guilty party when your hair turns green or shrivels up and dies. Colora, as far as I know, doesn't contain nasty metals. It might contain coal tar and Azo dyes, especially the cream version. People that are sensitive to PPD and other chemical dyes should be wary of Colora. Natural sources doesn't necessarily mean safe.
