easy to use and effective [SEP] this bubble dye is so easy to use this definitely had some small amount of bleach in it and had a little bit of damage i love airy brown since i was looking for a cooler shade the box only shows color results for levels and below and you will get those exact results shown on the box for lighter hair and above your hair could come out grey green you can see that in my ends which was about a level the top half was about i like it though and i m sure it ll fade over timesome people complain of not getting foam out and being too watery shake more times and wait minute before squeezing
