VITAMINS hair cosmetics Keratin Serum with Biotin, Castor Oil & Collagen

• SALON-SECRET SINCE 1943 - NOW AVAILABLE TO YOU - For 80+ years our family-owned, third-generation keratin formula was reserved for professional stylists. This is the same lightweight leave-in serum they used behind the chair - now in your hands, with biotin, hydrolyzed keratin, collagen, castor oil, argan oil, and coconut oil for glossy, resilient, salon-smooth hair at home
• 3-IN-1: LEAVE-IN + HEAT PROTECTANT + ANTI-FRIZZ FINISHER - One bottle replaces three products. Use it as a daily leave-in on damp hair, as a heat protectant before blow-drying or flat-ironing (up to 450°F styling tools), and as a midday smoothing touch-up. Saves room on your shelf
• TAMES FRIZZ + HUMIDITY FOR DAYS, NOT HOURS - Customers report hair stays smooth and manageable 3-4 days after washing - even in humidity. The keratin-collagen blend coats each strand to block frizz, smooth flyaways, and lock in a glass-like shine without stickiness, greasiness, or weigh-down
• WORKS ON EVERY HAIR TYPE - FINE TO THICK, STRAIGHT TO CURLY - Fine or thin hair? Use 1 drop. Medium or wavy? 2 drops. Thick, curly, or coarse? 3 drops. Safe for color-treated, bleached, highlighted, keratin-treated, and chemically processed hair. Sulfate-free, paraben-free, alcohol-free, cruelty-free
• ONE BOTTLE LASTS 4-6 MONTHS - LESS THAN $0.15 PER USE - At just 1-3 drops per application, this 4.25 fl oz bottle outlasts budget-friendly serums and costs a fraction of premium salon brands. Backed by our 80-year family expertise: You will see visibly softer and shinier hair after your first use
