Your Best Hair Day. Every Day.

Living Proof Perfect Hair Day (PhD) Conditioner is the science-backed, multi-tasking conditioner that delivers everything your hair needs in a single step — smoothness, strength, frizz control, and shine — without the heavy, greasy feel of traditional conditioners. Powered by Living Proof's patented Healthy Hair Molecule (OFPMA), this innovative formula conditions the hair while creating an invisible shield that repels dirt, oil, and humidity — so your hair stays cleaner, smoother, and more manageable for longer between washes. The 32 oz size is perfect for daily use, ensuring you never run out of your hair's new best friend.

Key Benefits

• Smooths and detangles hair for effortless combing and a polished, frizz-free finish
• Strengthens the hair fiber to reduce breakage and improve resilience over time
• Patented OFPMA molecule creates an invisible shield that repels dirt, oil, and humidity to keep hair cleaner longer
• Adds brilliant shine without greasiness, heaviness, or buildup
• Lightweight formula that conditions without weighing hair down — suitable for all hair types

How to Use

After shampooing, apply a generous amount of PhD Conditioner to clean, wet hair from mid-lengths to ends. For fine hair, avoid applying directly to the roots to prevent weighing hair down. Use your fingers or a wide-tooth comb to distribute evenly and detangle. Leave on for 2–3 minutes to allow the conditioning agents to fully penetrate and coat the hair fiber. Rinse thoroughly with cool water — cool water helps seal the cuticle and lock in smoothness. Use after every shampoo for best results. The 32 oz size is ideal for regular use and offers excellent value for daily washers or households with multiple users.
