I have recently had a number of older clients with fairly bad dry eye tell me they can only have their lashes tinted with Coal Tar free lash dye, so Refectocil is out, unless I use their sensitive formula. Has anyone had luck with this or another brand that is coal tar free? My experience is the colors don't develop to be as deep or last as long. Thanks for any info!
We use German Intensive... no coal tar, seems to last very well.
