For Carlsbad clients who need extension and color correction expertise, Killer Hair by K brings certified Bellami extension installation to a private studio on Marron Road between Jefferson and Monroe Streets. The service menu pairs Bellami Infinity weft and 24-inch tape-in systems with balayage and Brazilian blowout treatments, a hand-tied and adhesive range that complements the keratin smoothing protocols dispensed at Brazilian Keratin Bar on Jefferson Street. Full foil highlights and single-process color form the core of the chemical menu, with each formula customized to protect strand integrity on previously lightened hair. That integrity-first approach extends to the extension-matching process, where custom blending ensures color continuity between natural roots and added length — a precision-matching standard echoed by the shade-matched nail artistry at CV Beauty Collective in Carlsbad Village. Three-row Bellami Infinity weft installations use silicone-lined micro-ring beads that distribute weight across the occipital bone without adhesive contact, reducing traction stress on the natural hair shaft.
