How often can I apply this shampoo to my hair

I would say it depends on how often you wash your hair because this is a dye shampoo.. it's not permanent dye. Works well to cover the gray.

Never used the product in the image but I have used the black shampoo. You'd have to go read the label.

how long does it last?

The product last about 3 weeks with 2 times a week shampooing.

Needed a temporary black dye for ren faire back in September. I thought this was a safe bet since many of the reviews complained that it washed out too quickly. Put it on my husband's long golden brown hair, and apparently his hair is very porous because in January, it's still black! We've tried several non-chemical removal methods and it's sticking strong. Good, if that's what you're looking for... Not so good if you're looking for a temporary dye. I dye mine regularly with semi permanent and I've had to refresh my color twice since we dyed his.
