simpler hair colour, hypoallergenic 100% vegan formula is made in the USA and uses TDS, which is safer and gentler on your skin compared to PPD, a more aggressive ingredient used in many other dyes. Our innovative can doesn’t need any mixing and our dye doesn’t drip, so no mess. One can gives you as many uses as up to 4 boxes of drugstore dyes (single-use) and can be used and reused for your hair, beard, and touchups. No need for separate products. And, it's 100% recyclable when you're done
