To preserve your hue, you'll need to pamper your hair a bit.

Check local regulations. Share: If you have a friend or family member who might want to use it, consider giving it away, as long as it's still in good condition. Always remember to store leftover dye in a cool, dark place and ensure it's sealed tightly to prevent it from drying out or leaking.
After you finish the entire process, use a cuticle closer or ``after-dyeing'' treatment to seal, or at least quell, the shaft of your hair, which in turn locks in the colour and helps it last. You can get these things at places like Sally Beauty Supply.

Adapt your washing routine.
Extremely hot water can strip your hair of color, so we always advise color clients to use warm water when they shampoo and cooler water when they condition to decrease fading. Water at cooler temps seal the cuticle, so that it can hold the color longer.

- Cool Water Only: Hot water fades colour fast: keep it cool or lukewarm when washing and be sure to use a shampoo for coloured hair that will protect the colour. - Less is More: Don't wash your hair too often. Use dry shampoo to keep it fresh between washes. Keep your hair safe from daily damage.
Once you've cracked open that hair dye, here's the deal: aim to use it within the next 6-12 months. 📆 After this stretch, it's wise to bid it farewell and grab a fresh one. Why? To ensure your hair gets the top-notch treatment it deserves for that vibrant color you're aiming for.

Limit washing your hair to once or twice per week. Gray hair dye faces faster than most, so the less you wash your hair, the longer your color will stay.
