PARALLEL PRODUCTS3% 10 Volume Tint Developer - 25mL - Oxidant for Coloring - Mix with Luxe Spot Color Cream Dye/Kit

Use this to mix with Refectocil eyebrow dye. It makes the dye more long lasting than with my previous product. Will definitely purchase again.

This developer works great, the color lasts much longer

I really love this product, I’ve tried a bunch of different brands (purchased on Amazon) and was soooo happy when I found this!! Highly recommend.

I give 4 stars only because the entire contents of of bottle were spilled, and less than half of material remained. The quality of the material is good, pleasant to work with. But it’s a shame that I spent money and received less than half of the contents. But I like the product. I re commend.

Good investment! Cheaper than salon every few weeks! I leave on for twenty minutes.

It worked better than I expected. My eyelashes are just dark enough that they look natural but don't stand out too much if I'm not wearing eyeshadow. I left it on my eyebrows a little longer than I meant to, but they also came out a nice shade so don't worry about ending up with crazy eyebrows if you put on too much or leave it on a little long.

This product was amazing! I have sensitive skin and eczema, and I had no reaction with beautiful results that were easy to achieve at home!

I have always used Intensive tiny so when I discovered a luxury version I immediately hit add to cart. I’m less than thrilled with the product think the original is better leaves your skin splotchy and runs pretty frequently would not buy again
