Blonding & Blonde Specialist in Poway, CA
Healthy, dimensional blondes — from your first time going lighter to bright, lived-in maintenance.
Going blonde — and staying blonde — is equal parts artistry and hair science. At The Cosmo Lab in Poway, Serena specializes in blonding that looks bright and dimensional without sacrificing the health of your hair. Whether you’re lightening for the first time or fixing brassy, uneven color from somewhere else, she builds a plan around what your hair can actually handle.
Your blonde is custom-formulated and finished with a toner or gloss to land the exact shade you want — cool, neutral, or warm — then sealed with a nourishing treatment so it stays soft and shiny. For bigger transformations, Serena maps out a realistic timeline so you reach your goal without compromising your hair’s integrity.

Blonding & Blonde Specialist questions, answered.
How long does it take to go blonde?
It depends on your starting color and hair health. Some blondes are achieved in one visit; bigger transformations from dark hair are done over a few sessions to protect your hair. Serena maps out a realistic timeline at your consultation.
Will blonding damage my hair?
Lightening is always done with bond protection and finished with a nourishing treatment, and Serena will never push your hair past what it can safely handle. Hair health comes first.
How do I fix brassy or yellow blonde?
A toner or gloss neutralizes unwanted warmth and refreshes your shade. Many clients come in just for toning between full appointments to keep their blonde cool and bright.
Do you do blonde balayage?
Yes — hand-painted blonde balayage is one of Serena’s specialties for a soft, lived-in grow-out.
