How long does henna last

HI, 
I was wondering does anyone know the average shelf life of  jamilia henna, i wanted to buy the henna in bulk like 10 boxes at a time but i dont want them to go to waste , if for whatever reason , i dont use them that often. Also does anyone know any online henna vendors of jamilia henna that accepts cards other than paypal seems like everyone only wants paypal.  This will be my first time doing henna:)[You must be registered and logged in to see this image.]

Paypal is a safe way to purchase over the internet for buyer and seller. In my opinion paypal is a sign on a legit seller--no matter what it is i'm buying online. That's probably why you're seeing that as the major way to pay.

You can store your henna in the freezer to keep it fresh. I believe even outside of the freezer henna is good for over a year.

I agree with Jonezy about the paypal...you should feel safe using it when purchasing online.

I bought Jamilla henna from Amazon, which is safe, like Paypal and I had no problems. I havent used it yet but the seller was quick in sending the product.

Im with adiaha, I use Amazon to purchase my henna without any issues also my henna shipped the next day. I store mine in the freezer in the boxes until Im ready to use.
