I've been using henna a while now and I recognized the intensity of the previously frozen, so yesterday morn, I mixed and froze it and applied my henna at midnight. I think I will always use the prev. frozen batch.
@banjogirl,- research henna from other regions if you need extra grey coverage. Henna from Yemen is supposed to be very good, if you don't want to use indigo. I use Rajasthani, which had a nice dye content and covers my grey area well. Check out hennasooq's blog on their site for more info.
