What hair dye can i use ? That wont cause as much damage. Aside from HANA.
Try SheaMoisture's color line! It's in select Targets.
What kind of color are you going for? Try a DIY hair lightener using honey, cinnamon & water. Let these ingredients soak for about 45 minutes to an hour and you'll notice a brighter, vibrant blondish color (even on naturally dark hair). The more often you do this ( I do it like twice a month) and the more you go out in the sun, you'll notice a brighter change! Just make sure you use a nourishing oil to revive dry curls.I like Garnier Triple Nutrition Miracle Dry Oil : http://www.naturallycurly.com/curlproducts/view/9950/garnier-fructis-triple-nutrition-miracle-dry-oil-styling-products-5-oz
I've been using L'Oreal Feria Professional for years now and no problems. I also use the conditioning treatment from the line and sit under the hair dryer for 30 minutes with plastic cap. No hair dryer, keep plastic cap on for 60-90 minutes.
