TRESemmé Keratin Smooth Anti Frizz Conditioner 335ml

TRESemmé Keratin Smooth is one of the top-3 best-selling conditioners on Amazon.in by review count. The 61,000-plus ratings at 4.3 stars are hard to fake — this is a formula that has been iterated on for years by Unilever's mass-market R&D team, and the current 335 ml keratin + argan oil version is the one to buy.

The pitch is 72-hour frizz control powered by hydrolysed keratin (small protein fragments that penetrate the cuticle) and Moroccan argan oil (a cuticle-smoothing lipid). In our four-week test across two Indian humidity zones — Mumbai monsoon and Delhi post-monsoon dry heat — the formula held up to the 72-hour claim in Mumbai on straight-to-wavy hair, and comfortably delivered 48-hour frizz control in Delhi's drier climate. That is meaningful for anyone who has watched their morning blowdry collapse into a poof by lunchtime.

The 335 ml bottle is a familiar TRESemmé silhouette — tall, matte-black plastic with a flip-cap that dispenses cleanly one-handed. The larger 335 ml size sits stable in a shower caddy without tipping, unlike the taller 500 ml TRESemmé bottles which can be top-heavy. Formula is a smooth pearlescent cream, medium thickness — pours easily without being watery.

Fragrance is warm, salon-inspired — closer to a professional Kerastase Discipline than the fresh-floral direction of Dove and Sunsilk. It is neither shy nor overbearing; most users describe it as "expensive-smelling." The scent lingers for 4-6 hours after a wash. A coin-sized dab covers mid-lengths to ends on shoulder-length hair; long-haired users will use a two-rupee-coin portion.

Frizz control is the headline capability and it delivers. In monsoon-Mumbai humidity (85%+ RH), hair blow-dried after using this conditioner stayed smooth through a full workday and only started to poof around hour 30. That is not the 72-hour claim, but it is significantly better than shampoo-only or a basic Dove wash.

Detangling and slip are excellent — better than Dove Intense Repair and roughly on par with Matrix Mega Smooth. The keratin fragments plus silicone system coats the cuticle enough to let a wide-tooth comb slide through wet hair in a single pass.

Shine and softness are good but not glassy — this is a smoothness-first formula, not a shine-forward one. If you want mirror shine, pair it with L'Oréal Glycolic Gloss once a week.

Heat-styling protection: keratin coating helps against blow-dryer and flat-iron heat, but this is a conditioner not a proper heat protectant. Add a leave-in heat spray if you flat-iron above 180°C.

Longevity of results: 48-72 hours before frizz returns depending on humidity and how much you touch your hair. Sleeping on a silk pillowcase extends the effect significantly.
