The TRESemme Keratin Smooth Anti-Frizz Hair Serum is a leave-in styling serum designed to control frizz, add shine, and protect hair during heat styling. It earns an AI Score of 90/100 on Flash AI, drawn from 2647 verified reviews across 5 platforms, with frizz control rated at 95/100 and shine and softness at 90/100. That volume of consistent feedback across platforms gives this serum a reliable track record, particularly for users dealing with persistent frizz.
The formula combines four listed ingredients: Argan Oil, Keratin, Cyclopentasiloxane, and Dimethiconol. Argan Oil conditions the hair shaft, adding softness and natural shine. Keratin helps smooth the cuticle, targeting frizz at a structural level by closing the surface of each strand. Cyclopentasiloxane is a lightweight, fast-spreading silicone that gives the serum its fluid, non-greasy texture and allows even distribution across hair lengths. Dimethiconol coats each strand with a smoothing, glossy film that locks in the results. Together, these four ingredients deliver the silky, polished finish that reviewers consistently describe.
This serum suits adults with dry or frizzy hair across all hair types. Its lightweight texture makes it viable for fine hair without weighing strands down. The product highlights claim protection against 80% humidity for 48 hours and heat protection up to 230 degrees, which adds practical value for regular heat styling. One honest note: some buyers report inadequate packaging on delivery, with instances of damage or poor sealing on arrival. The product itself performs well, but you should check the seal when your order arrives and buy from a reputable seller to avoid this issue.
You can find this serum priced from ₹170 to ₹1,275 across 14 sellers, with variation based on platform and seller. At the lower price points, the value proposition is strong. The consensus across 2647 reviews confirms frizz control, shine, softness, and economy of use, with reviewers noting that a small amount covers full lengths from mid to ends. Flash AI recommends this serum for daily use on frizzy or dry hair, especially in humid conditions. Compare prices across sellers before buying and prioritise those with strong delivery ratings.

"Absolutely love the Tresemme Keratin Smooth Anti-Frizz Hair Serum! It's a total great product for my hair. My biggest struggle has always been frizz ..."
"Works well Tried many products for my frizzy hair in the past, but this is the best so far. I apply after hair wash to towel dried hair. The effect shows up after 1-2 hours. Reduced fizz and smoother hair up to 2 days until next hair wash. Great product"
Apply 2-3 pumps evenly on damp or dry hair, from mid lengths to ends, and do not rinse. You can use it daily as a leave-in styling step before your usual routine. Reviewers note that a small amount covers the full length, so daily use does not deplete the product quickly, making it practical for a consistent routine.
Yes. The serum is formulated for all hair types, including fine hair. Its lightweight, non-greasy formula absorbs quickly without weighing strands down or leaving them flat. If you have fine hair, start with 1-2 pumps rather than the full 2-3 pump recommendation to gauge how your hair responds before increasing the amount.
Keratin is a structural protein naturally present in hair. In this serum, it helps smooth the hair cuticle, which reduces frizz by closing the surface of each strand. This works alongside Argan Oil and the silicone ingredients to deliver a sleeker, more uniform finish from root to tip.
Results are visible from the first application. Reviewers consistently report immediate frizz reduction and added shine after a single use. The product highlights reference salon-like smooth hair with regular use, suggesting that consistent daily application builds on the initial results over time.
Some buyers have reported poor packaging on delivery, with instances of damage or inadequate sealing on arrival. This does not affect product performance once it is intact, but it can be frustrating on receipt. Buy from a reputable seller with strong delivery ratings and check the seal when your order arrives.
This serum uses a silicone-based formula with Cyclopentasiloxane and Dimethiconol, which coat the hair shaft for targeted frizz control, a polished finish, and heat protection up to 230 degrees. A basic hair oil tends to be heavier and does not offer the same lightweight, non-greasy texture or the specific frizz-sealing action that a keratin-based serum provides.
This serum is available from ₹170 across 14 sellers on various online platforms. Prices vary significantly across sellers, so comparing before you buy is worthwhile. Choosing a seller with good delivery and return ratings also reduces the risk of packaging damage on arrival.
The serum is lightweight and non-greasy, absorbing quickly without leaving a sticky or heavy residue. Reviewers describe hair feeling silky and looking glossy after application. It gives a smooth, polished finish without making hair appear wet or weighed down, even when used on fine hair.
This serum contains Cyclopentasiloxane and Dimethiconol, both widely used silicones in leave-in hair care products. They coat the hair shaft to smooth and add shine, and both are considered safe for cosmetic use at standard concentrations. The serum is also confirmed paraben-free in its specs, which is an additional formulation consideration for daily users.
Yes. The serum functions as a daily leave-in styling product with no rinse required. It is paraben-free and cruelty-free, and the lightweight formula does not cause greasiness or a heavy feel with regular use, based on reviewer feedback. The economy of use, with a small amount sufficient per application, also makes a daily routine practical and cost-effective.
