I wish I still lived in SF!.
Allison is the best stylist that I know. It's just a side benefit that she charges less than half of what other salons charge. I have dark dark brown hair, and she made me platinum blonde. It took 7 applications of the dye and two days to do so, but it turned out perfect! I'd recommend her to anybody traveling to SF. She's off the beaten path, and easy to miss, but well worth the trip to the Richmond District.
