Surya Brasil Products Henna Cream, Chocolate, 2.37 Fluid Ounce

I didn't see hanna on the ingredients list. Why?

How long does this last and how many washes does it take to rinse out ?

What is the current expiry date for burgundy? They sent me two bottles that were 2-3 weeks from expiry date last time and the color did not stick.

so this contains everything I need, yes? no mixing of products? just one bottle with liquid that I put onto my hair and rub in, yes? Tx
