Hair Color By Agnes
A jet-set colorist's island atelier tucked into the hills of Colombier.
Why Go
When Miami socialites, Parisian editors, and Monaco regulars fly in for a St Barth escape, many of them quietly book Agnes before they book dinner. This is the island's most in-the-know address for hair color, run by a Paris-born, Caribbean-raised master colorist whose highlight work has a cult following on three continents.
The Experience
Agnes's studio sits inside the Immeuble Flary on the Allée Bois Neuf, up in the quiet green folds of Colombier — a world away from the Gustavia bustle. The setting is intimate and appointment-only, which is exactly the point: you get her, her hands, and her eye for the entire session. Trained in Martinique, Paris, and London, Agnes built her own method around the Caribbean light, so the color she paints on in her chair is calibrated for exactly the sun you're about to walk back out into. Expect long, unhurried conversations in French, English, or a mix of the two, espresso between foils, and the kind of pampered, off-the-radar feeling that makes St Barth regulars keep her number saved under 'emergency.'
What to Try
Her signature California blonde and fine, hand-painted highlights are what most people fly in for — the balayage is soft enough to grow out beautifully once you're back home, which matters when your colorist splits her year between St Barth, Miami, LA, and Paris. If you're brunette, ask about a gloss or dimensional lowlights to bring your color back to life after a week of sun and salt. Blowouts and cuts are available, but color is the headline act.
Insider Tip
Book before you book your flight. Agnes only takes a handful of clients a day and her chair fills up months ahead during high season (Christmas through March, and again around the Bucket Regatta). DM the @haircolorbyagnes Instagram directly rather than trying to walk in — Colombier is not a neighborhood you casually pop by, and she confirms appointments personally. Bring a photo reference in the same lighting you'll be wearing the color in (i.e., beach, not office).
The Practical Stuff
Location: Immeuble Flary, Allée Bois Neuf, Colombier 97133, St Barthélemy. About a 15-minute drive from Gustavia and 20 minutes from the airport — you'll want a rental car or a pre-booked taxi, as this end of the island is residential. By appointment only; no set posted hours. Contact via Instagram @haircolorbyagnes. Payment and pricing discussed at booking; expect Paris/Miami-tier rates for a session with a master colorist. Come with clean, dry, product-free hair unless told otherwise.
