TRESemmé Keratin Smooth Shampoo 22 oz — Frizz Control, Marula Oil Shine

TRESemmé Keratin Smooth Shampoo (22 oz) is a keratin- and marula-oil–infused cleansing formula designed to reduce frizz, detangle, boost shine and leave hair soft for up to 72 hours when used as a system.

This full-size 22-ounce bottle is part of the Keratin Smooth collection and is formulated to give hair a sleeker, more manageable finish while preserving natural movement. The shampoo works with the TRESemmé Keratin Smooth Conditioner and styling products to deliver a five-benefit routine: fight frizz, remove tangles, increase shine, add touchable softness and tame flyaways. It’s a salon-inspired formula aimed at smoothing hair without flattening it, suitable for daily or frequent use.

How does this shampoo help control frizz on humid days?

The formula combines keratin, which helps strengthen and smooth the hair surface, with marula oil to add lightweight conditioning. Together they create a barrier that reduces moisture-induced swelling of the hair shaft, so strands lie flatter and look less frizzy.

• Keratin smooths cuticle layers to reduce surface roughness.
• Marula oil provides lightweight hydration and gloss.
• Designed to work over time as part of the Keratin Smooth system.
• Helps tame flyaways for a neater finish when styled.

Will this shampoo make my hair limp or weighed down?

TRESemmé Keratin Smooth is formulated to balance smoothing with body, so hair remains touchable and retains natural movement. It cleanses without heavy residue and is intended to smooth rather than coat the hair, preventing a flat or greasy look when used correctly.

• Lathers to remove dirt and light buildup without over-stripping.
• Leaves strands soft but not oily, preserving volume near the roots.
• Best paired with the matching conditioner for controlled smoothing.
• Suitable for regular use on most hair types seeking smoother texture.

How should I use it for the best results at home?

Apply the shampoo on wet hair, gently massage into the scalp to build a lather, then rinse thoroughly. Follow with TRESemmé Keratin Smooth Conditioner to lock in the smoothing benefits, and for heat styling protection, use the Keratin Smooth Heat Protection Spray before blow-drying or straightening.

• Wet hair, massage roots to ends to activate cleansing and smoothing agents.
• Rinse well and apply matching conditioner to mid-lengths and ends.
• Use heat protection spray when using hot tools to maintain results.
• Regular use as part of the system helps extend frizz control up to 72 hours.

Is this shampoo suitable for colored or chemically treated hair?

The formula is designed to be gentle enough for many hair types, including color-treated hair, though individual sensitivity varies. It focuses on smoothing and detangling; if color preservation is a priority, consider alternating with a dedicated color-safe shampoo.

• Helps detangle and smooth color-treated strands without heavy buildup.
• Contains conditioning agents to maintain softness and shine.
• Alternate with color-protecting products for longer-lasting tone.
• Patch-test if your hair is highly porous or recently chemically processed.

Who is this for: TRESemmé Keratin Smooth Shampoo 22 oz is aimed at people who want frizz reduction and smoother, shinier hair without sacrificing movement. It’s a good choice for those with dull, frizz-prone, or tangled hair who use heat styling and want salon-inspired results at home. If you prioritize color longevity above all, pair it thoughtfully with color-safe care.
