* eBay: This is probably your best bet. Search frequently, as listings come and go. Be prepared to pay a premium, especially for unopened bottles.
* Etsy: Similar to eBay, you might find vintage sellers with old bottles.
* Online Auction Sites: Keep an eye on other online auction sites besides eBay.
* Vintage Shops: Check local antique stores or vintage shops, particularly those specializing in beauty products or retro items.
* Flea Markets and Yard Sales: It's a long shot, but you never know what treasures you might find.
* Online Forums and Groups: Look for online communities dedicated to vintage beauty products or discontinued shampoos. Members might have leads or be willing to sell.
* Specialty Discontinued Product Websites: some websites specialize in finding old discontinued products.
Important Considerations:
* Authenticity: Be very careful about authenticity, especially on online marketplaces. Look closely at photos and read seller reviews.
* Condition: Be aware that vintage shampoo may have degraded over time. It might not smell the same, and its effectiveness could be diminished.
* Price: Expect to pay a significant premium for a genuine bottle of "Gee Your Hair Smells Terrific," especially if it's unopened.
* Alternatives: There are modern shampoos that try to emulate the original's scent. Look for shampoos with notes of cherry almond. Read online reviews for comparisons.
Good luck with your search!
