I dye lashes and brows with a semi-permanent dye. It’s best suited for light- to medium-colored lashes and brows. The process takes about 15 to 30 minutes and can be combined with a facial. Your lash tint should last about a month depending on how you cleanse and moisturize your skin as oils can dissolve semi-permanent color. The dyes are not permanent so there will be a slow fading of color over time.
Humans have dyed their lashes for hundreds of years. The ancient Egyptians famously used kohl around their eyes, brows, and eyelashes for a dramatic effect. Medieval Europeans and South Asians also mixed oil with black powder to create eye makeup.
