Living Proof Perfect Hair Day Shampoo & Conditioner 32 Oz Set

The Living Proof Perfect Hair Day (PhD) Shampoo and Conditioner 32 oz Set is a scientifically engineered duo designed to transform hair from the very first wash and continue improving its condition over time. At the heart of both formulas is Living Proof's patented molecule OFPMA (Octafluoropentyl Methacrylate), a breakthrough ingredient that mimics silicone's five key benefits — detangling, slip, sleekness, conditioning, and shine — using an eco-luxe sunflower-based approach, while keeping hair cleaner for longer between washes. The sulfate-free, silicone-free, and oil-free shampoo uses a blend of mild amino acid-based cleansers — including Sodium Lauroyl Methyl Isethionate and Sodium Methyl Cocoyl Taurate — to gently yet thoroughly remove impurities and buildup without stripping moisture, maintaining a scalp-healthy pH of 4.0–4.5. The conditioner pairs OFPMA with a cationic sugar beet derivative that hydrates and reduces static and flyaways, a moisturizing ester that detangles while delivering glossy shine, hemisqualane to seal the cuticle for silky smoothness, and a marine algae polysaccharide (Furcellaria Lumbricalis Extract) that shields strands from environmental damage and preserves color. Together, the duo delivers proven 72-hour hydration, five hallmark benefits of beautiful hair — smoothness, volume, conditioning, strength, and polish — and results that are visible instantly and build with repeated use. The finish is weightless and never greasy, making this set ideal for anyone with dull, dry, or generally healthy hair of any type who wants a high-performance daily regimen in an efficient, salon-sized 32 oz value format. A light, fresh citrus fragrance completes the sensory experience. How to Use Wet hair thoroughly, then apply the PhD Shampoo and massage into a rich lather from roots to ends before rinsing completely. Follow immediately with the PhD Conditioner, applying from mid-lengths to ends and leaving on for 1–2 minutes to allow the formula to fully penetrate the hair shaft. Rinse thoroughly with water and towel dry. For best results, use together consistently — results improve progressively with each wash.
