Key Ingredients

  • Healthy Hair Molecule: Smooths, protects and polishes by forming a weightless shield around each hair strand
  • Thickening Molecule: Deposits microscopic thickening dots between strands so hair looks and feels naturally fuller
  • Tucuma Butter: Conditions dry and damaged hair
  • Conditioning Styling Polymer: Provides thermal protection and soft, flexible hold to maintain your style even in high humidity

How To Use

Apply to damp hair. Blow dry.

  • 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


For curly hair, use with a diffuser. To increase the hold, mist damp or dry hair with Style Lab Flex Hairspray.

If you have very fine hair and typically seek out volumizing products, PhD 5-in-1 Styling Treatment may not give you the amount of volume you desire. We recommend using Full Thickening Mousse (alone if you have baby fine hair or you can layer it with PhD 5-in-1 Styling Treatment).

If you have very coarse hair and typically seek out smoothing products, PhD 5-in-1 Styling Treatment may not give you the level of sleekness you desire. We recommend layering with No Frizz Nourishing Styling Cream or using Restore Smooth Blowout Concentrate.
