How long does it last?

It depends on how it was applied: if going for a more semi-permanent hold it needs to be processed with the hair covered in a plastic cap and under a hood dryer for at least 30 mins. If applied that way - should last for several weeks (depending on how often one shampoos hair). If applied and processed 10-15 minutes and no applied heat - will last probably for a week or two (depending on how often one shampoos hair).

How many bottles do you get for 12.37?

Just one. But one bottle can do at least 6 applications, depending on length of hair. It's a great product, and I've been using it for 10 years.

Does the cream soda color work on dark hair

The Cream Soda is the color I mostly.use. I have dark brown hair along with some gray around edges. It does lighten my hair! Best color, although I sometimes mix it with Bold Gold (1/2 & 1/2.) Lasts 2-3 months with weekly washing.
