New Henna with Leftover Henna

Hi, I henna my hair last weekend and plan on to do it again this weekend. I was wondering if its okay to use the leftover henna I saved in a plastic container not plastic bag to put in my new mix.

I decided to put in a plastic container because to me it made no sense putting in a ziploc bag and getting all messy.

When I have leftover henna, I freeze it. Then if I need to make more henna on the next application, I thaw the fromzen henna and mix the two. Works just as good for me. HTH.

Sorry, I got a typo in there. That should read "frozen" and not fromzen. lol.
