Revlon SmoothStay Straightening Brush Review: Budget Styling for Thin to Medium Hair

Revlon-SmoothStay-Straightening-Brush-review-featured

✨ Quick Take: Is It Worth It?

The Revlon SmoothStay is a budget-friendly ceramic paddle brush with 10 digital heat settings (250–430°F) and a generous 4.5″ × 1.6″ surface for faster coverage. It’s well-suited to fine and medium hair types that need quick, everyday smoothing, and the dual voltage makes it handy for travel. The tradeoff is its modest bristle tension and bulkier paddle, which struggle with thick or textured strands and make root styling less precise.

✅ Best for: Fine-to-medium hair seeking affordable, quick smoothing with digital heat control
❌ Skip if: You have thick, coarse strands or want a brush that reaches roots and short layers easily

🎯 Who Should Buy the Revlon SmoothStay

✅ Fine to medium hair needing gentle daily smoothing
✅ Straight–wavy (1A–2C) textures
✅ Beginners who want simple, safe controls
✅ Short–medium lengths
✅ Travel users (dual voltage + auto-off)

🚫 Skip It If You Have:

❌ Coarse/dense or 3B–4C textures needing high tension
❌ Expect flat-iron-level straightness
❌ Need tight root access or precision on short layers
❌ Prefer a lighter/less bulky head near the scalp


✨ Design & Build

The Revlon SmoothStay uses a rectangular paddle shape that maximizes coverage across its 4.5″ × 1.6″ heated surface — one of the largest tested. This makes it efficient for straightening longer sections in fewer passes, though the bulky size can feel less precise at the roots or on shorter layers.

Its 1.2 cm heated teeth are slightly shorter than average, which limits penetration into dense or coarse hair, while the 1.5 cm detanglers provide moderate grip for guiding strands. Together, this setup works best for fine to medium textures but struggles to deliver enough tension for thick or coily hair.

Safety is built-in with outer cool-touch bristles forming an anti-scald shield, while plastic detangler bristles help distribute hair evenly for faster coverage. The handle is 1.4″ wide, making it chunkier than average, but the soft-touch grip and ribbed housing improve security and comfort during use.

Verdict on build: Wide and user-friendly for fine/medium strands, though bulky for roots and less effective on thick hair due to shallow heated teeth.

💡 Performance & Technology

The SmoothStay features 10 digital settings from 250°F to 430°F in ~20°F increments, giving users flexibility across hair types. In testing, it reached 415°F, close to its claim and among the hotter performers in this price range.

The brush includes ionic technology (though no separate ion generator), which helps reduce static and frizz. Combined with ceramic heating plates, it delivers smoother results than basic budget brushes. However, real-world feedback shows that users with thicker, wavy textures often need multiple passes and may still not achieve fully straight results, even at the highest heat. For fine or medium hair, though, it produces quick, polished smoothing.

It also features smart heat memory (though the indicator light is faint and hard to read) and a 60-minute auto shut-offfor safety.

According to a PubMed study on heat treatment effects, frequent exposure to temperatures above 400°F can weaken the cuticle and keratin structure, leading to cumulative damage. The SmoothStay’s upper settings should therefore be reserved for resistant textures, while finer strands benefit from lower ranges.

The American Academy of Dermatology also advises using styling tools with adjustable temperature control and limiting repeat passes to reduce breakage — guidance that aligns well with the SmoothStay’s multiple heat settings.

Verdict on performance: Affordable and versatile for fine-to-medium hair, but less effective on coarse or thick strands despite high temperature claims.

🔌 Ergonomics & Convenience

At 11.3 oz, the SmoothStay is slightly heavier than average, but not unmanageable. Its 11″ body provides leverage for longer sections, though the larger paddle can feel awkward near the scalp.

The 6 ft cord is shorter than the category average (7.6 ft), limiting maneuverability, especially in professional or large setups. On the plus side, it includes dual voltage for travel, digital controls with an LED display, and a soft-touch handle with ribbing for improved grip.

The lack of a Velcro strap for storage is minor, but the brush’s bulk and shorter cord make it less convenient than premium models.

Verdict on usability: Easy to operate with digital precision, travel-friendly, and comfortable in-hand — but bulky and limited in reach.

👉 If you’re looking for a simpler budget tool with a long warranty, the Remington Shine Therapy review is worth a look.
