How many applications can I get from one kit, and how should I store it between uses?

The 30 ml dye cream and 20 ml developer bottle are proportioned for roughly 20 full brow-and-lash sessions when mixed in the recommended ratio. If you only tint brows, you'll get more uses; if you tint both brows and lashes each time, expect closer to the stated number.

After opening, squeeze excess air from the developer bottle before capping — oxygen accelerates oxidation and weakens the developer. Keep both containers in a cool, dark cupboard (not the bathroom, where heat and humidity fluctuate). The dye cream can thicken slightly over time; if it becomes lumpy or separates, discard the kit. Always check the expiry date on the box before starting a new session.

For hygiene, never dip a used brush back into the original bottles. Dispense the amount you need into a small glass or plastic dish, mix there, and apply from the dish. This prevents contamination and extends the usable life of both components.
