I did it, i did at home ammonia free, i had ombre done after first tri.or sometime during the 3months in june. Then went over it all to do a good transition, then touched up my roots later, and just last month went over my entire hair to go dark again and one color. Keep it ventilated, ammonia free, and i also did my roots last so it wasn't too long on it. Lastly my hair dresser had told me as well its ok to dye hair. Hope that helped a little.
