Just mixed my henna gloss

I just finished mixing my henna gloss receipe and I plan to let it sit overnight. Do I need to put it in the fridge?? I only have a TWA and I probably won't use it all. What do I do with the leftovers?

Yep! ^ Freeze it!

I thawed out a batch yesterday afternoon and put it on last night, Im about to wash it out here pretty soon.

I have found myself making batches and freezing them a head of time So I can do henna treatments on the fly.

Plus, I think I get more colour if it's been previously frozen. (but! I could just be crazy.)

Simply

I think you get more color too. My frozen henna seems to pop the color on my hair a lot faster.
