I purchased my hair and had it installed by a licensed professional with experience. This is my first time using Donna Bella hair. She toned my hair and washed with Sulfate free shampoo when she went to blend and cut the hair they slid out. The tape was mushy and a waste. My stylist called and spoke to them and they told her that you had to wait 48 hrs. Before toning and cutting. Their solution was to re-tab the hair and clarify it and do another install. This added extra expense that is very annoying and costly. I have had other brands installed and never had this issue. Very disappointing... Really look into other options.
