How I DIY Dye My Eyebrows in 5 Minutes Grab your kit. I use medium brown! Here’s what’s included! Use one capsule per use. Open up a capsule and dump it into the little cup. Squirt a little developer cream into the cup and mix it all up! Start with clean and dry brows. Apply the solution to your brow (I do one at a time) and make sure to coat all the hairs. Wait 1-2 minutes depending on desired color. Remove thoroughly with wipe. Repeat steps on other brow. I use a wipe to remove but also make sure to wash my face after for a double cleanse. All done! And they’ll develop even darker overnight. Just wash the cup/ brush so you can re-use for next time! The box comes with 20 capsules (20 uses).
