Please Help! Deep Condish n Henna

So I live in the middle of nowhere, Wisconsin, and completely forgot to order Aubrey Organics Honeysuckle Rose online in order to deep condish after I do my VERY FIRST henna treatment tomorrow. I called all the natural stores in my area (within a 35 mile radius) and none of them have it in stock. Is there any deep conditioners anyone could recommend that I could just purchase from Target or Wal-Mart. Also, my Target does not sell anything like Miss Jessie's.

Sometimes I use Aussie 3 minute miracle but I don't know if it is deep enough for a henna treatment. It's really good though.
