A classic long layer and buttery-California-blonde never goes out of style! It may be a relaunch of Caroline Bessette-Kennedy to remind some of us what's tried and true, but that true soft blonde is *always* a stable! Quiet luxury and timeless beauty.

Soft S waves are having a moment in our salon! �This is my current go to finish for creating movement, polish, and a refined lived in look.
Using a 1¼ inch curling iron and subtle direction changes to enhance dimension without looking over styled. Style that gives hair the body and movements, bringing out tones and texture while giving beachy-carefree-vibe 🏝️🐚
Would you rock this style?
