How to Use the Shark SmoothStyle Heated Comb: Full Smooth-Blowout Routine

If you just unboxed a Shark SmoothStyle — or you’ve had one for a week and your results still don’t look like the TikTok videos — this guide is for you. The SmoothStyle is a dual-mode tool: one side of its personality is a heated-air blow-dry brush for damp hair, and the other is a heated smoothing comb for dry hair. Most disappointing results come from using the wrong mode at the wrong moisture level, or from skipping the small technique details (section size, rotation, indicator light) that Shark’s own instructions call out.

By the end of this guide you’ll know exactly which mode to use when, how to run a full wet-to-smooth blowout routine from shower to finished hair, and how to fix the most common problems — snagging, limp roots, and hair that won’t stay smooth.

What the Two Modes Actually Do

The SmoothStyle’s control is a rotating ring at the base of the handle. According to the user guide, the positions are: off, low air temperature, medium air temperature, high air temperature, and smoothing mode [2].

Mode	What it uses	Hair state required	What it’s for
Wet Hair Mode (low/med/high air)	Heated airflow through the brush head	About 70% dry [1]	Wet-to-dry volumizing and blow-dry styling
Dry Hair Mode (smoothing mode)	Heated smoothing combs on the barrel edges	100% dry [1]	Straightening, aligning and smoothing; taming frizz and flyaways

Two details matter here, straight from Shark’s official FAQ and manual:

• Wet Hair Mode is not for soaking-wet hair. Shark says hair should be about 70% dry before you start — rough-dry it with a towel or regular dryer first [1].
• Smoothing mode is for completely dry hair only. The heated smoothing combs have their own indicator light: it glows yellow while heating and turns green when the combs are hot and ready [2]. Independent testing by Marie Claire Australia reported the ceramic-coated plates reach around 215°C, with roughly a two-minute heat-up [3].

Before You Start: Prep Checklist

• Wash and condition as usual, then towel-dry or rough-dry to about 70% dry [1]
• Apply a heat protectant through the lengths (standard practice with any hot tool; if you’re using a new styling product, patch-test it first and stop if it irritates your skin)
• Fully detangle — Shark specifically recommends detangling before styling to avoid snags [1]
• Clip hair into workable sections; smaller sections give more control and smoother results [1]
• Make sure the air-inlet filter at the bottom of the handle isn’t blocked by your hand or hair [2]

Step-by-Step: The Full Smooth-Blowout Routine

Phase 1 — Wet Hair Mode (the blow-dry)

1. Rotate the control ring to an air setting. Start with medium; use high for thick or coarse hair, low for fine or fragile hair [2].
2. Work in small sections. Take a section roughly the width of the brush head. Keep the hair concentrated around the middle of the brush head — Shark notes this helps avoid snagging at the top or bottom edges of the brush [1].
3. Brush from roots to ends with tension. For a smooth finish, pull downward at the roots. Hold the cool-touch tip with your free hand for extra control [2].
4. For volume, flip and brush from underneath. Shark’s FAQ recommends flipping your head upside down and brushing from underneath to volumize in Wet Hair Mode [1]. The Marie Claire reviewer used the same trick directionally: downward at the roots for smoothness, lifting up on the top layers for volume [3].
5. Repeat until hair is fully dry. As a reference point, the Marie Claire reviewer reported drying thick, coarse hair in about 15 minutes [3]. Your time will vary with hair density and length.

Phase 2 — Dry Hair Mode (the smooth)

1. Rotate the ring to smoothing mode and wait for green. The heated-comb indicator glows yellow while heating; only start styling when it turns green [2].
2. Take a small, fully dry section. Hair must be 100% dry in this mode [1].
3. Rotate the brush 360° as you pass through. This is the step most people miss: turning the barrel a full rotation ensures the hair passes through both sets of heated smoothing combs on the barrel’s narrow edges, which is what actually sets the smooth finish [1].
4. Move slowly from mid-length to ends, keeping light tension. Use it to tame flyaways around the hairline last, once the rest of the hair is set.
5. Finish and cool. Switch the ring to off. Let the combs cool completely before you put the tool away [2].

Shark SmoothStyle How to Use It on Different Hair Goals

• Sleek and straight: After the Phase 1 blow-dry, do a full Phase 2 pass in small sections, brushing downward with steady tension and the full 360° rotation.
• Bouncy blowout: Spend more time in Wet Hair Mode with the upside-down volumizing technique at the roots [1], then use smoothing mode only on the top layer and ends to polish frizz.
• Quick refresh on second-day hair: Skip Phase 1 entirely. On fully dry hair, use smoothing mode to reset flyaways and bends — this is the fastest way to use the tool on non-wash days.

All of the above are cosmetic styling results — the SmoothStyle smooths, aligns and reduces the appearance of frizz; it doesn’t change your hair’s underlying structure or health.

Common Mistakes and Troubleshooting

These are drawn from Shark’s own support guidance and independent reviews — labeled accordingly.

• Hair snags at the edge of the brush. Shark’s FAQ addresses this directly: keep the section concentrated around the middle of the brush head, detangle fully first, and use smaller sections [1].
• Smoothing mode doesn’t seem to smooth. Two usual causes: hair wasn’t 100% dry (residual moisture undoes the finish) [1], or the barrel wasn’t rotated 360°, so hair never passed through both heated combs [1]. Also confirm the indicator light was green before you started [2].
• Blow-dry takes forever. Start from ~70% dry as Shark recommends rather than dripping wet [1], and check that the air-inlet filter at the base is clean and unobstructed — a clogged filter chokes airflow [2].
• Results fall flat by midday. Reviewers report better hold when the style is locked in with a dry-mode pass at the end; the Marie Claire tester found the style held through the day with minimal frizz after finishing with the heated combs [3].
• Tool smells warm or airflow feels weak over time. The manual prescribes monthly filter cleaning (see below) [2].

Maintenance: Keep It Working Like New

Per the user guide [2]:

1. Switch the unit off and unplug it.
2. Let the heated smoothing combs cool completely before storing.
3. Once a month, clean the air-inlet filter at the bottom of the handle: brush dust and debris off with a clean, unused toothbrush.
4. Never cover or block the inlet filter during use.

FAQ

Can I use the Shark SmoothStyle on wet hair? Yes — that’s what Wet Hair Mode is for — but Shark says hair should be about 70% dry first, not dripping wet. Smoothing mode, by contrast, is strictly for 100% dry hair [1].

How do I know when smoothing mode is ready? Watch the heated-comb indicator light: yellow means the combs are still heating, green means they’re hot and ready to style [2].

Does the SmoothStyle work on all hair types? Shark markets the HT202 for all hair types, with three air-temperature settings to match hair thickness [2]. An independent reviewer with thick, coarse hair reported a full dry in about 15 minutes [3]. Very fine hair generally does better on the lower air setting and quick passes in smoothing mode.

Do I still need heat protectant? It’s sensible practice with any heated tool — independent reviewers used one, and the smoothing combs run at straightener-level temperatures (around 215°C per Marie Claire’s testing) [3]. Patch-test any new leave-on styling product before full use.

How is this different from a regular straightener? A flat iron only works on dry hair and clamps it between plates. The SmoothStyle combines a heated-air drying brush and heated smoothing combs in one tool, so you can go from damp hair to a finished smooth blowout without switching devices [1][2].

Verdict + Where to Get It

The SmoothStyle earns its reputation as a genuinely simple two-in-one: rough-dry to 70%, blow out with the air modes, then lock everything in with a green-light smoothing pass. The technique details — small sections, mid-brush placement, the 360° rotation — are what separate a frizzy “meh” from the glassy finish the tool is capable of. If you want one tool that replaces the dryer-brush-plus-straightener juggling act on busy mornings, this is an easy recommendation.
