Paul Mitchell Super Skinny Serum

Silicone smoothing serum and blow-dry primer.

Paul Mitchell Super Skinny Serum is a concentrated silicone-based primer that smooths frizz, seals the cuticle and shields hair during blow-drying and hot-tool styling. The lightweight formula absorbs without weighing strands down and resists humidity for a glossy, polished finish.

Why Choose It?

• Frizz Smoothing: Silicones (Dimethicone, Dimethiconol) seal the cuticle for a sleek, polished finish that holds in humidity.
• Heat Protection: Shields strands during blow-drying, straightening or curling up to 450°F / 232°C.
• Faster Blow-Dry: Lightweight, fast-absorbing primer that speeds up drying time before styling.
• Weightless Finish: Concentrated formula — 1-2 pumps is enough, even on fine hair, without greasy build-up.

Best For

Frizzy, thick or coarse hair that needs taming before a blow-dry, plus anyone who uses hot tools and wants a thermal shield. Suitable for all hair types — start with one pump on fine hair.

Apply to damp, towel-dried hair before blow-drying — not soaking wet hair. Highly concentrated, so start with one pump.

• Shampoo and condition hair as usual.
• Towel-dry until damp.
• Pump 1-2 pumps into your palms and rub hands together.
• Distribute evenly through mid-lengths and ends, avoiding the scalp.
• Blow-dry and style with your preferred hot tools.

Tips

• Pair with a Paul Mitchell smoothing shampoo for frizz-prone hair to prep hair before the serum step.
• On fine hair, stick to one pump on mid-lengths and ends only — too much weighs roots down.
