For that intimate yet public encounter, the shearing of the locks, you want a swank yet comfy place where you can air your innermost thoughts while the stylist soothes away all your glitches. You want to leave cheered and refreshed, energized, capable of magnificent feats. Darin David's salon on upper Solano Avenue does all this and more: the space is inviting and stylish; the music is picked to calm yet intrigue; the staff is up on the latest in hair shaping and products as well as Berkeley's news of the day. Hair stylist Victor Wu is really a sculptor; he works with grace, innovation, and kindness. After a visit to his chair, you're ready to put on your superhero cape and tackle the world. The salon uses nature-friendly Aveda products and works hard at not polluting the planet. Receptionist Gwynne Coffee remembers your name and greets you with your favorite hot beverage. To sum it all up, a visit here is cheaper and more satisfying than going to your shrink or your chiropractor ... and, unlike those, it yields results that you can see immediately in the mirror.
