Hairdoo Voodoo, which has (/had?) been in business for 22 years, has apparently abandoned its location at 520 Waller. The space is now completely empty.

We've reached out to the owner, and will update this post with any more details. If anyone has information about this sudden and mysterious disappearance, please let us know! Update 6/8/2010: We've heard back that Hairdoo Voodoo has relocated to the Mission -- 3150 18th Street, specifically! Their new number is (415) 863-1100, in case you'd like to get in touch.
