I used this color about a month ago and it's still very vibrant. It depends on how often you wash your hair and what kind of shampoo you use. Low sulfate or no sulfate shampoos work the best for keeping color locked in.
I love ion and if you take less showers and use dry shampoo it stayed in my hair which mind you gets greasy really easy and with that method it stayed in my hair for like 2 months fanned watching and bidding
