A lash lift and black tint was done on one of my clients. The tint on her upper lashes took very well but her bottom lashes did not get nearly as dark, nor did it last very long. I'm guessing that the upper lashes took better because they were chemically processed by the lift, where the lower lashes were not, but she wants them the same color. I'm not sure if it has anything to do with the tinting product that was used, maybe it just wasn't a very good one, or because of the lift process. So, before I give her any advice or try anything to help her with this, I'm wondering if anyone else has had this issue and,if so, what did you do to help your client? Any information on this would be greatly appreciated by the both of us!! Thx!!
