Allergy free lash tint

I used refectocil eyelash tint for about 3 months before I developed a severe allergy to it (picture above, isn’t that just lovely?) 90% sure it’s to the ingredient PPD (which is a common allergen and ingredient in majority of lash dyes) I’ve been on the hunt for some sort of tint I could use on my lashes or something I can put on them that’s not mascara that will make them look darker for a couple of years now. I’m naturally blonde so I look like a naked rat without mascara, and I miss how nice my lashes looked when I used to be able to dye them. I wore clusters for about a year but they’ve destroyed my natural lashes and I also like the look of my lashes with mascara better, I just hate how they look without tint or mascara. If anyone has any sort of dye option or some sort of idea of something I can apply to them to make them darker that would be amazing!
