Style and treat in one genius solution. For the first time ever, our scientist combined our award winning, patented Healthy Hair Molecule (OFPMA) and our Volumizing Molecule (PBAE). PhD 5-in-1 Styling Treatment:

  • delivers the five benefits for a perfect hair day in one easy step- smoothness, volume, conditioning, strength and polish
  • styles and treats without compromising one for the other
  • keeps your style cleaner, longer
  • reduces breakage by 78%, making hair 4.5x stronger 

For all hair types. All Living Proof products are sulfate-free, silicone-free and oil-free. Safe and formulated for color and chemically treated hair.


On clean, damp hair, evenly distribute PhD styler from roots to ends. Comb through. For best results, blow dry.

Tips + tricks:

  • 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
  • When air drying, use slightly less product
  • For added volume, use with Full Root Lifting Spray or Full Thickening Mousse
  • For extra conditioning and smoothing, pair with No Frizz Leave-In Conditioner

The Problem: Silicones and oils are traditionally used to treat hair but they also can build up, attract dirt and oil and weigh hair down. Resins are used to create volume, but they can be stiff, easily flake and are short-lived. And forget about trying to combine silicones, oils and resins together. They simply don't mix, and this leads to bad hair day after bad hair day.

The Solution: Our scientists figured out a way to deliver it all. PhD 5-in-1 Styling Treatment is powered by our two award winning, patented molecules, OFPMA and PBAE, for volume, smoothness and treatment in one breakthrough, routine- changing step for beautiful, healthy hair.

  • styles and treats without compromising one for the other
  • repels dirt and oil to extend your style and allow you to wash your hair less often
  • transforms hair to its optimal condition
  • reduces breakage by 78%, making hair 4.5x stronger

Who is Living Proof's Perfect hair Day (PhD) 5-in-1 Styling Treatment for?

PhD Styling Treatment is for everyone looking for the perfect balance of treatment and styling benefits in one product for smoothness, volume, conditioning, strength and polish.

Can I blow dry and air dry my hair when using PhD Styling Treatment?

Yes, PhD Styling Treatment works well when air drying and blow drying. Each technique gives a different look. Blow dry hair section by section for extra smoothness and/or body and volume. For a more bodified blowout use a round brush. For a sleek blowout use a flat brush. Apply PhD Styling to damp hair and allow hair to air dry for a smooth, healthy style with natural body and enhanced curl pattern.

How is PhD Styling Treatment different than No Frizz, Full and Restore?

PhD Styling Treatment has been formulated specifically to give the ideal balance of all five benefits women seek in beautiful, healthy hair: smoothness, volume, conditioning, strength and polish. It is not about concentrating on any one benefit in particular, but rather the combination of all five.

  • No Frizz is designed to eliminate frizz by blocking humidity and control harmful moisture flux. 
  • Full is designed to deliver maximum thickness, fullness and volume that lasts, is touchable and revivable. 
  • Restore is designed for repairing and protecting dry or damaged hair. 

We certainly encourage consumers to choose products from across our franchises as a complement to PhD Styling Treatment – whether that is our Restore Mask for in-shower additional treatment, or Prime for extending their style, or No Frizz to help with additional frizz-fighting power, or Full Root Lifting Spray for extra height. 

What is the fragrance in PhD Styling Treatment?

The scent is a similar light citrus fragrance to what is found as most other Living Proof products. It will not smell identical to any other product, though, as each product is formulated differently.

Does it have any heat or UV protection?

Yes, PhD Styling Treatment offers both heat and UV protection. It contains ingredients that creates a weightless barrier to protect hair from the heat up to 450 degrees and contains UV defense that absorbs harmful, damaging UV rays from the sun.

Can PhD Styling Treatment be layered with other Living Proof products?

Yes, PhD Styling Treatment can be layered with other Living Proof products to enhance benefits. When layering with PhD Styling Treatment, use slightly less than you would if you were using it alone. 

Are there any tricks for styling your hair with PhD Styling Treatment?

  • For best results, style with a blow dryer. The performance of PhD Styling Treatment is enhanced with heat. 
  • Blow dry with a round brush to enhance volume and body.
  • Blow dry with a flat brush to create a smooth, polished blowout.
  • Finish with a flat iron for a sleek finish.
  • Finish with a curling iron for soft waves.
  • If you plan on air drying hair, we recommend you use slightly less product than you normally would. The result is a smooth, healthy style that accentuates your natural body and volume. If you have naturally curly or wavy hair, PhD will enhance your curl pattern.
