TRESemmé Keratin Smooth Shampoo 4-Pack 28 fl oz — Keratin frizz control for salon-style blowouts up to 72 hours

TRESemmé Keratin Smooth Blowout Shampoo is a keratin-infused, salon-inspired shampoo that helps smooth frizz and align hair cuticles for up to 72 hours.

Designed to bring professional blowout results to your daily routine, this 4-pack supplies ample shampoo for repeated styling and long-term use. The formula combines keratin with a lamellar-discipline system to reduce frizz, improve shine, and make hair easier to manage before heat styling. Free of parabens, mineral oil, and DMDM hydantoin, and PETA-certified cruelty-free, it’s intended to work alongside the Keratin Smooth Blowout Conditioner and styling products in the collection.

How will this shampoo tame frizz in everyday use?

The keratin-rich formula smooths and helps align raised cuticles, reducing the surface roughness that causes frizz. With continued use and when paired with the matching conditioner, hair lies flatter and reflects more light, creating a sleeker appearance for days after washing.

• Infused with keratin to help restore and smooth cuticle alignment
• Designed to deliver up to 72 hours of visible frizz control
• Best results when used as a set with Keratin Smooth Conditioner

Can I use this if I heat style frequently?

This shampoo supports heat styling by preparing hair with smoother, more uniform strands for better heat application. For higher-temperature styling, follow with TRESemmé heat-protectant styling spray to protect up to 450°F and help lock in your blowout or straightening routine.

• Prepares hair for heat tools by reducing frizz and tangles
• Pairs with TRESemmé Protecting Heat Styling Spray for elevated protection
• Promotes longer-lasting styles when used with the full Keratin Smooth regimen

Is this product formulation safe and ethically made?

The shampoo is formulated without parabens, mineral oil, and DMDM hydantoin, aligning with cleaner personal-care preferences. TRESemmé also holds PETA certification for cruelty-free practices, so the product is not tested on animals during development.

• 0% parabens, mineral oil, and DMDM hydantoin in the formula
• Certified Cruelty-Free by PETA
• Produced to salon-inspired standards for everyday at-home use

What complementary products should I use for best results?

To maximize smoothness and longevity of your style, follow the shampoo with the Keratin Smooth Blowout Conditioner, then incorporate styling aids like mousse or silk serum for volume and shine. Finish with an extra-hold hairspray to keep your look in place while maintaining the smooth finish.

• Start with Keratin Smooth Blowout Conditioner after shampooing
• Use Keratin Smooth Blowout Mousse for lift and body
• Seal with Keratin Smooth Blowout Silk Serum and Extra Hold Hairspray
