TRESemmé Keratin Smooth Blowout Shampoo 4-Pack 28 fl oz — Frizz Control, Heat-Ready

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

Designed to deliver professional-quality smoothing at home, this four-pack of 28 fl oz bottles gives frequent stylers a dependable base for heat styling and long-lasting frizz control. Formulated without parabens, mineral oil, or DMDM hydantoin and Certified Cruelty-Free by PETA, the Keratin Smooth Blowout Shampoo works with the rest of the Keratin Smooth Blowout system to prepare strands for sleek styles while helping protect against the thermal stress of styling tools.

How does this shampoo reduce frizz during everyday styling?

The formula uses keratin and lamellar-discipline technology to help align and smooth individual hair cuticles, which reduces friction between strands and lowers the appearance of frizz. That smoother surface reflects light better for a sleeker finish after blow-drying.

• Keratin helps rebuild and smooth the hair surface
• Lamellar-discipline assists cuticle alignment for less flyaway
• Use with matching conditioner and styling products for best results
• Promotes smoother blowouts that last up to 72 hours

Will this shampoo work with heat styling tools?

This shampoo is formulated to prepare hair for heat styling by smoothing the cuticle and reducing surface roughness, which supports more efficient heat application. For additional protection, pair it with TRESemmé Protecting Heat Styling Spray when using tools up to 450°F.

• Smoother strands mean more even heat distribution
• Compatible with heat-protectant sprays for up to 450°F styling
• Best used as part of the Keratin Smooth Blowout regimen
• Helps produce a professional-looking blowout at home

Is this shampoo safe for color-treated or sensitive hair?

The formula is free from parabens, mineral oil, and DMDM hydantoin, reducing exposure to some common irritants; however, results vary by individual and dye type. If you have chemically treated or highly porous hair, test a small area first and consult your colorist for tailored advice.

• 0% parabens, mineral oil, and DMDM hydantoin
• PETA Certified Cruelty-Free formulation
• Gentler-than-some salon-strength clarifying shampoos
• Patch-test if you have a sensitive scalp or recent color service

How should I use this shampoo for the best blowout results?

Start by massaging the shampoo into wet hair, focusing on the scalp, then rinse thoroughly. Follow with the Keratin Smooth Blowout Conditioner, and finish styling with recommended TRESemmé heat-protectant and finishing products for long-lasting smoothness and hold.

• Wash with Keratin Smooth Blowout Shampoo and rinse well
• Apply Keratin Smooth Blowout Conditioner mid-length to ends
• Use Keratin Smooth Blowout Mousse for volume if desired
• Finish with Silk Serum and Extra Hold Hairspray for shine and hold

Who is this for: This four-pack is ideal for people who blow-dry regularly, anyone seeking salon-style smoothness at home, and households that want a cost-effective supply of a professional-grade smoothing shampoo. It suits those looking to minimize frizz and improve blowout longevity while avoiding certain common additives; if you have highly specific scalp conditions or medical concerns, consult a professional before switching products.
