Eyebrow henna is easy and convenient to use. It gives your eyebrows a defined shape and a beautiful, deep color. The innovative formula requires no mixing with a activator. The effect lasts up to 4 days. This formula is enriched with Bio Argan Oil, which conditions the eyebrows. Application: Before use, apply face cream around the eyes to protect the skin from smudging. Apply henna to the eyebrows using the applicator. Wait 7-10 minutes, then wash the henna off with lukewarm water using a cotton ball. For optimal coloring effect, degrease and dry your eyebrows before applying henna. Do not apply to eyelashes. Note: Hair dyes can cause severe allergic reactions! Perform a patch test 48 hours before each use. Allergy test: Apply a small amount of the product to the inner forearm, leave it on for 10 minutes, and then wash it off. If no redness or irritation occurs within 24 hours, begin treatment.
