Color-treated hair that frizzes and gets heat-styled: anyone who blow-dries straight hair smooth, or diffuses waves and curls and wants them defined rather than fuzzy. Pureology lists it for all color-treated hair types prone to frizz.

It suits people who live with humidity and want one product that handles smoothing, shine and heat protection. Since it is heat-activated, it is less useful for anyone who only air-dries.

Most frizz shows up during and after styling, when damp hair dries unevenly and the cuticle lifts. Silkmorphose is designed for exactly that moment: it goes on damp hair, and the heat of the dryer or diffuser activates it, smoothing the strand as it dries and leaving a glossy, sealed finish that holds up better against humidity.

It also replaces a separate heat protectant, with protection up to 450°F (230°C), which keeps a frizz routine down to fewer products. Used after Smooth Gloss Shampoo and Treatment Mask it completes the system Pureology tested for its frizz and shine results.

• Push the trigger to unlock it and shake well before use.
• Spray generously and evenly onto damp hair, focusing on mid-lengths and ends.
• Activate with heat. For a sleek finish, blow-dry with tension using a brush. For curls, use a diffuser to define the style.
• For best results, use after Smooth Gloss Shampoo and Treatment Mask.

Pros

• Combines frizz control, shine and heat protection up to 450°F in one step
• Works for sleek blow-outs and for diffused curls
• Very fine, weightless mist that doesn't leave hair sticky
• Pureology says results build: frizz reduces further with each use

Cons

• Heat-activated, so air-drying won't give the full effect
• Contains a silicone polymer (polysilicone-29), which matters if you follow a silicone-free routine
• Pureology's 72-hour figure is for the full shampoo, mask and spray system
• Fragranced; the trigger has to be unlocked before the first spray
