TRESemmé Keratin Smooth Conditioner for Frizzy Hair — 4 Pack, 28 fl oz each, Keratin + Lamellar-Discipline for 72hr Smoothness

TRESemmé Keratin Smooth Conditioner is a keratin-infused conditioner designed to align hair cuticles and reduce frizz for smoother, sleeker hair for up to 72 hours when used as part of the Keratin Smooth regimen.

Designed for people who want salon-inspired smoothness at home, this value 4-pack delivers the same professional-grade formula TRESemmé is known for. The conditioner uses keratin and Lamellar-Discipline technology to help tame flyaways and create a polished blowout finish. Free of parabens, mineral oil, and DMDM hydantoin, and PETA-approved, it fits into a cruelty-free routine while supporting heat styling and long-lasting manageability.

How does this conditioner help with frizzy hair?

The formula works by aligning surface cuticles and smoothing the hair shaft so strands reflect light more evenly and resist humidity-induced frizz. It complements heat styling by preparing hair for a sleeker blowout and improving overall combability.

• Keratin infusion targets weakened areas to smooth strands.
• Lamellar-Discipline technology helps control cuticle alignment.
• Supports up to 72 hours of reduced frizz when used with the Keratin Smooth system.

Will this protect my hair from heat styling?

While the conditioner itself helps smooth and detangle hair in the shower, it is intended to be part of a routine that starts with Keratin Smooth Shampoo and follows with styling products for thermal protection. Using the full regimen improves resilience to heat and helps lock in a long-lasting blowout.

• Prepares hair for heat by reducing surface friction and tangles.
• Pairs with Keratin Smooth styling products for added protection.
• Encourages a sleeker finish that responds better to blow-drying and flat-ironing.

Is this formula safe for daily use and sensitive scalps?

The conditioner is formulated without parabens, mineral oil, and DMDM hydantoin, reducing exposure to certain common additives while keeping a salon-quality performance. For most users it’s suitable for routine use, but anyone with scalp conditions or severe sensitivities should patch-test or consult a dermatologist.

• 0% parabens, 0% mineral oil, and 0% DMDM hydantoin in the formula.
• PETA-approved, cruelty-free product standard.
• Suitable for frequent use for many hair types; patch-test if you have a sensitive scalp.

How should I use it to get the best results?

For optimal smoothness, start with Keratin Smooth Blowout Shampoo, apply this conditioner focusing on lengths and ends, leave in briefly, and rinse. Continue with Keratin Smooth Blowout Mousse for volume or Silk Serum for shine, then finish styling and set with Extra Hold Hairspray as needed.

• Wash with Keratin Smooth Shampoo first for best cuticle alignment.
• Apply conditioner from mid-length to ends; leave 1–2 minutes before rinsing.
• Follow with recommended Keratin Smooth styling products and heat tools for a lasting blowout.

Who is this for: This 4-pack is ideal for people with naturally frizzy, unruly, or thick hair who want consistent salon-style smoothness without frequent shopping. It’s also convenient for households, frequent stylers, or anyone building a Keratin Smooth routine—especially those who value cruelty-free formulas and prefer long-lasting frizz control paired with heat styling.
