1. How It Performs at the Sunday Salon Backbar & At Home
Behind the chair at Sunday Salon at Raleigh Iron Works in Raleigh, NC, our colorists and stylists prescribe Davines Heart of Glass Instant Bonding Glow Leave-In Serum (10.14 fl oz / 300 ml) as a cornerstone Step 2 treatment in the Heart of Glass line—specifically engineered for porous, over-processed blonde strands needing instant cuticle sealing, anti-frizz discipline, and high-refraction shine.
After lightening services, glosses, or daily heat styling, the hair cuticle develops microscopic gaps that allow moisture and color molecules to escape. Davines Heart of Glass Instant Bonding Glow Leave-In Serum penetrates directly into those porous zones, smoothing the outer cuticle scales without collapsing natural root volume.
Our Raleigh guests immediately notice the difference in wet-combing slip in the shower: knots melt away effortlessly with a wide-tooth comb, reducing mechanical breakage and sealing in glass-like softness that holds up against North Carolina humidity.
2. Ingredient Chemistry, Sustainability & Botanical Profile
Hero Bioactive — Biacidic Bond Complex & Illuminating Amino-Concentrate: Engineered specifically for natural and lightened blondes using Davines’ patented Biacidic Bond Complex, Fortifying Botanical Shield, and natural Jagua Blue extract (Genipa Americana) to balance brassiness while reinforcing disulfide bonds.
Cuticle-Smart Delivery & Color Protection: Every bottle of Davines Heart of Glass Instant Bonding Glow Leave-In Serum is pH-balanced to keep the hair cuticle sealed and reflective. By targeting damaged, negatively charged sites along the hair shaft, the formula delivers intensive nourishment where your mid-lengths and ends need it most while preserving the vibrancy of your Sunday Salon dimensional color or gloss.
B-Corp Sustainability & Sensory Profile: Formulated and bottled at the Davines Village in Parma, Italy using 100% renewable clean energy and carbon-neutral Zero Impact® packaging, this formula features an elevated aromatic profile of refined botanical white florals and clean biodynamic citrus.
3. Stylist Application Guide: How to Apply by Hair Type
- Step 1 — Squeeze Out Excess Water (Crucial Salon Secret): Before applying Davines Heart of Glass Instant Bonding Glow Leave-In Serum, gently press excess water out of your hair with your hands or a microfiber towel. Waterlogged hair dilutes concentrated Italian masks and conditioners by up to 50%.
- Fine to Medium Hair Application: Work a nickel-sized amount from ear-level down to the ends, avoiding the top two inches of the scalp. Detangle gently from the bottom up using a wide-tooth shower comb, leave on for 3 to 5 minutes, and rinse thoroughly.
- Thick, Coarse, Curly, or Lightened Hair Application: Section damp hair into 2–4 quadrants and smooth a generous quarter-sized amount through mid-lengths and ends. Twist into a clip and allow the formula to penetrate for 5 to 10 minutes (or wrap in a warm towel for a Sunday Salon spa treatment at home) before rinsing cool.
- Routine Pairing Tip: After towel-drying, lock in the conditioning benefits with Davines OI All in One Milk or your preferred Davines leave-in thermal shield before heat styling.
