Blonde Hair Trends in Castro Valley

How to decide which shade of blonde? Here is a breakdown of popular blonde hair shades (like Warm Blondes) to give you some inspiration.

What is hair color correction?

We specialize in hair color correction, a broad term for fixing color problems, removing unwanted hair dye, and making complex color changes.

Vivid Hair Color

Make a big statement with your vivid hair color, or just add subtle hints. Studio W Salon is here to help you express your personal style.

Transitional Grey Hair

Unlike a root touch up, with a transitional grey hair service, we don't color your roots - we color the rest of your hair to match your grey and natural salt and pepper pattern.
