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

Henna cream takes 7 to 10 washes to complete 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.

Although I didn’t use the Burgundy color I try to give an answer on some typical questions in connection w/this product. Remember this is a Henna product and does not color fast product has to stay much longer in your hair than normal. 2x or 3x longer and pls take 1 or 2 shades darker to get a more desired color. Hair should be clean and not greasy. No hair conditioner before using this product. Shake well before each use and using the product 2 or 3 weeks after expiration date does not make a difference even several months up to a year. Keep product in a cool and dark spot! Success!

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

Yes, it's ready to go. Just put it on your hair, put a shower cap on it for an hour, rinse it out, and you're good to go. Your hair will be silky soft, beautifully colored, and the color will last 2-3 weeks. I've been using it for years, and I love it.
