Drybar The Baby Brush Crush Review: Travel-Friendly Touch-Up Tool

Drybar-The-Baby-Brush-Crush-Mini-Straightening-Brush-review-featured

✨ Quick Take: Is It Worth It?

The Drybar Baby Brush Crush is a mini ceramic paddle straightening brush built for bangs, flyaways, and travel touch-ups. At just 5.5 oz and 8″ long, it’s lightweight and dual-voltage, making it a true carry-on companion. Its fixed 400°F heat smooths fine-to-medium strands quickly but offers no adjustment, which can be too hot for fragile hair and not powerful enough for thick textures.

✅ Best for: Travelers, shorter styles, or quick smoothing on fine-to-medium hair
❌ Skip if: You need adjustable heat, full-length styling power, or a tool for coarse/coily textures

👍 What We Like

  • Incredibly lightweight (5.5 oz) and compact (8″)
  • Smooths bangs, flyaways, and short layers quickly
  • Ionic ceramic surface adds shine and cuts frizz
  • Cool-touch bristles feel safer near the scalp
  • Dual voltage + 60-min auto shut-off for travel

👎 What We Don’t Like

  • Fixed 400°F may be too hot for fine/damaged hair
  • Lacks tension and surface area for thick/coarse hair
  • No display or temperature control
  • Best for quick styling/refreshes—not full, dense heads

🔑 What Sets It Apart

  • Mini 8″ body & 5.5 oz weight — among the smallest travel brushes
  • Fixed 400°F temperature — consistent and hot (IR ~385°F after 15 min)
  • 3.0″ × 1.0″ heated surface — compact but fast for touch-ups
  • Cool-touch bristles + auto shut-off = safer for travel
  • Dual voltage for international use

❌ Anyone needing a digital display or advanced features


✨ Design & Build

The Baby Brush Crush is Drybar’s travel-sized ceramic paddle-shaped straightening brush, designed for touch-ups, bangs, bobs, and flyaways. At 8″ long, it’s noticeably more compact than a standard straightening brush, giving better control on short hair and making it easy to pack for travel.

Its 3″ × 1″ heated surface is intentionally small, offering precision on short sections but not the speed needed for full-head straightening. The 1.8 cm heated teeth pair with 1.6 cm detanglers to create light–medium tension, suited for fine and medium textures. Cool-touch outer bristles serve as the anti-scald shield, helping you work close to the roots safely. The plastic bristle structure spreads hair evenly across the ceramic surface, improving consistency despite the miniature footprint.

The build is minimalistic: no ribbed housingno soft-touch coatingno LED display, and no digital controls, matching its role as a simple, grab-and-go device.

Build Verdict: Compact, safe, and ideal for quick smoothing; too small for efficient full-head straightening or coarse textures.

💡 Performance & Technology

The brush heats to a preset 400°F, which we measured at 385°F during testing. With no adjustable temperature and preset increments, it simplifies operation but limits suitability for fragile, color-treated, or very fine hair that benefits from lower heat.

The ceramic heating system distributes heat evenly, while ionic technology (without a separate ion generator) helps reduce static and smooth the cuticle. This aligns with Dyson Hair Science principles showing how uniform heat and ion action reduce raised cuticles and frizz.

Because the heat is fixed at the upper end of the safe styling spectrum, short, fast passes work best — consistent with NCBI findings that prolonged exposure above 390–400°F increases cuticle stress. On straight, wavy, and medium-density hair, it creates a polished finish quickly; on coarse or tightly textured hair, the small plate and modest tension limit deep smoothing power.

We recorded a 90°F handle temperature, keeping it comfortable to grip. There’s no auto-temperature lock, but that’s irrelevant for a single-temp tool. A 60-minute auto-off provides safety for travel. It also has no smart heat memory, which again does not affect performance due to its preset heat.

Performance Verdict: Excellent for travel, touch-ups, and smoothing finer hair; not ideal for textured or coarse hair needing adjustable heat or higher tension.

🔌 Ergonomics & Convenience

At 5.5 oz, it’s significantly lighter than a standard straightening brush, reducing fatigue during fringe work and making the 1.1″ handle width comfortable even without soft-touch grip. The 8″ tool length improves precision on short hair and tight areas like bangs and face-framing pieces.

The 6 ft cord is shorter than the typical 7–8 ft range but works well for travel and small spaces. There’s no Velcro strap, though the shorter cord naturally packs compactly. The brush is dual-voltage, making it more versatile for international use. Controls are minimal — non-digital, no LED — which keeps operation simple. A 2-year warranty provides solid long-term reassurance for a compact device.

Usability Verdict: Ultra-light, maneuverable, and ideal for travel or fast fixes. Its fixed temperature, smaller surface, and modest tension limit performance on coarse textures or full-head straightening.
