TRESemmé Keratin Smooth Keratin Infusing Smoothing Serum

It’s a 10 Miracle Leave-In Plus Keratin

WHAT IT DOES: Everything—seriously. This leave-in treatment delivers a whopping 10 benefits: it repairs damaged hair, adds shine, controls frizz, protects hair color, detangles, prevents split ends, stops breakage, creates silkiness, adds volume, and protects against heat damage all with the added benefit of keratin.

IGK Good Behavior Spirulina Protein Smoothing Spray

BEST FOR: Opt for this spray to reduce your dry time.

HOW IT WORKS: Spirulina protein and a formaldehyde-free bonding polymer work in a similar way to a keratin treatment, meaning pin straight, smooth locks that won't waver in humidity.

USERS SAID: "This stuff is magic. It really does keep your hair shiny and smooth. Can't believe it is so inexpensive, but does such a great job! Love, love, love this cream."

Best Color-Safe Product For Flyaways

WHAT IT DOES: Just like your beloved raincoat protects you when the weather's at its worst, this product does the same for your hair. We aren't kidding—spray your hair with water, and it'll bead up rather than soak in.

HELPFUL TIP: The cross-linking polymers that form the moisture-proofing barrier are heat activated, so it's best to use this on damp hair before blow drying.

Olaplex No. 6 Bond Smoother Reparative Styling Creme

WHY YOU NEED IT: There's a reason this brand lines the shelves at so many top-notch salons. While many smoothing creams simply mask dryness and damage, Olaplex actually reverses and repairs it to make it healthier with each use.

FROM THE EXPERTS: This frizz-fighter promises to strengthen, hydrate, speed up blow-drying time, and control flyaways for up to 72 hours.

Living Proof Perfect Hair Day 5-In-1 Styling Treatment

WHAT IT DOES: Living Proof's patented thickening molecule leaves hair looking and feeling thicker while it smooths and conditions dry strands. 

WHY YOU NEED IT: This product also works to keep hair cleaner, longer by repelling dirt and protecting against humidity.
