Perfect Hair Day™ (PhD) 5-in-1 Styling Treatment

A brilliant treatment and styler that's formulated to smooth, strengthen, volumize, polish, and protect hair from heat damage in a single shot.

This cream is powered by Living Proof’s healthy hair molecule to smooth and protect by forming a weightless shield around each hair strand, while the thickening molecule creates space between strands for hair that looks and feels fuller. The result? Smooth, strong, voluminous hair—and endless compliments.

Key Benefits:

• Styles with volume and smoothness
• Conditions, strengthens, and adds shine
• Provides heat protection (up to 450°F/230°C) and UV protection

Highlighted Ingredients:

• Healthy Hair Molecule: Smooths and protects by forming a weightless shield around each strand—smoothing, strengthening, and polishing.
• Thickening Molecule: Deposits microscopic thickening dots between strands so hair looks and feels fuller.
• Tucuma Butter: Emollient rich in fatty acids, conditions dry and damaged hair.

HOW TO USE: Apply Perfect hair Day® 5-in-1 Styling Treatment to damp hair. Blow dry. To enhance body and volume, use a round brush when blow drying.

To create a smooth, polished style, use a flat brush when blow drying.

• For curly hair, use with a diffuser.
• To increase the hold, mist damp or dry hair with Living Proof Style Lab Flex Hairspray (sold separately).
• If you have very fine hair and typically seek out volumizing products, instead use Full Thickening Mousse (sold separately) alone if you have baby fine hair, or you can layer it with Living Proof PhD 5-in-1 Styling Treatment (sold separately).
• If you have very coarse hair and typically seek out smoothing products, layer this treatment with Living Proof’s No Frizz Nourishing Styling Cream (sold separately) or Restore Smooth Blowout Concentrate (sold separately).
