Storing henna and indigo correctly is really important to make sure you protect the potency of the hair dye.
You must always store henna powder and indigo powder in a cool, dry, dark place, out of sunlight, and out of the reach of children.
Unopened packets of Renaissance henna, indigo, cassia obovata, and other plant products, will easily last up to five years or longer if stored correctly.
But once opened, it’s best to use them within 12 months as they may be less effective after that. Seal opened henna and indigo packets with a peg or selotape. Store them away in the back of a cupboard or dry, dark place.
Storing Henna : Freeze Henna
You can freeze unopened henna powder for up to 3 years. And you can freeze freshly mixed henna paste in an airtight container for up to at least a month or longer. So next time you’re in a hurry you can simply defrost it by sitting it in a bowl of hot water and it’ll be ready to use in no time ! You can also defrost and heat it in the microwave.
Or Put It In the Fridge
Freshly mixed henna paste will keep in the fridge in hot weather for at least 2 days or longer. And although it is likely to keep for just as long on your counter top, it is better to cover it and keep it in the fridge to keep it as fresh as possible once the dye has released.
Alternatively, mix up your paste and put it straight in the fridge. Take it out the night before you want to use it, allowing seven to eight hours for dye release. You can then heat up the paste if you want to before applying it to your hair. Or just apply the cool henna paste straight to your hair. Either way will give you the same hair colour result.
There’s nothing better than cold freshly defrosted henna on your head and in your hair in the heat of summer time.
You can also try it also on the soles of your feet to keep your feet cool, but remember that they will turn orange !
Once you’ve got the hang of henna, you can buy the bigger quantity packs and mix lots of it in advance. After dye release, pack it into handy margarine size tubs in your freezer. It saves time.
