1. How It Performs at the Sunday Salon Backbar & At Home
At Sunday Salon at Raleigh Iron Works in Raleigh, NC, Davines OI All in One Milk is the single most-used prep formula across every styling station. Whether our colorists have just completed a dimensional lived-in balayage, a high-impact blonde foil service, or a precision dry haircut, this ultra-lightweight micro-emulsion is our non-negotiable foundation before a blow dryer or hot tool ever touches the hair.
Unlike traditional cream leave-ins that rely on heavy waxes or non-soluble silicones—which coat fine hair and cause flat roots by day two—OI All in One Milk uses an atomized liquid-to-milk delivery system. The moment it mists onto towel-dried strands, it equalizes porosity from root to tip, allowing a wet brush or wide-tooth comb to glide through freshly lightened or tangled hair with zero mechanical snapping.
During round-brush blowouts, it creates a breathable thermal buffer up to 450°F (230°C) while cutting blow-dry time and sealing the cuticle into a reflective, glass-like finish that resists North Carolina humidity without feeling coated or greasy.
2. Ingredient Chemistry, Sustainability & Signature OI Scent Profile
Antioxidant-Rich Amazonian Roucou Oil (Bixa Orellana): The hero bioactive powering the entire Davines OI line is sustainably harvested Roucou oil from the Amazon basin. Naturally containing 100 times more beta-carotene than carrots alongside ellagic acid, Roucou oil restructures the hair fiber, neutralizes UV and thermal free radicals, and preserves salon color vibrancy between gloss appointments.
Provitamin B5 (Panthenol) & Amino-Functional Conditioning Complex: Panthenol penetrates the cortex to bind moisture inside dehydrated mid-lengths and ends, while cationic amino acids selectively target negatively charged, damaged cuticle sites—meaning the formula conditions exactly where your hair needs repair without weighing down healthy roots.
The Iconic OI Fragrance & B-Corp Sustainability: Formulated in Parma, Italy using 100% renewable energy in carbon-neutral Zero Impact® packaging (free of parabens and sulfates), OI All in One Milk carries Davines’ unmistakable warm botanical signature—an elevated blend of warm amber, creamy sandalwood, subtle rose, and sweet resin that lingers softly in the hair all day.
3. Stylist Application Guide: How to Apply by Hair Type
- Fine or Low-Density Hair (2–4 Sprays): Gently squeeze excess water from your hair with a microfiber towel. Instead of spraying directly onto the crown, mist 2 to 4 sprays directly into your palms, rub your hands together, and work through the mid-lengths and ends before combing through. You can skip rinse-out conditioner entirely on days you want maximum root lift.
- Medium, Color-Treated, or Balayage Hair (5–8 Sprays): Mist evenly across towel-dried hair from ear-level down to the ends, holding the bottle 6–8 inches away. Comb through with a wide-tooth comb to distribute evenly before blow-drying or air-drying.
- Coarse, Curly, or High-Porosity Hair (8–12 Sprays + Layering): Section damp hair and apply 8 to 12 sprays throughout to unlock knots and hydrate thirsty curls. For maximum frizz sealing in humid weather, cocktail by layering 1–2 drops of Davines OI Oil or LOVE Curl Cream right over top.
- Day-2 Dry Hair Refresh: Mist 1–2 pumps into dry palms and lightly smooth over slept-on ends or flyaways to revive softness and bounce without re-wetting your blowout.
