To join the Birthday Program, you must provide your full name, full address and birthday. Once enrolled in this program, you will be sent a postcard within 28 days of your birthday that must be brought to your nearest participating Aveda Experience Center to receive your free gift (no purchase necessary). You will also receive communication from Aveda on events, new product launches, special offers and seasonal sampling mailers.
