Best Hair Straightener for Thick Hair in Australia (2026 Guide)

If you have thick, coarse, or long hair, you already know—not all hair straighteners are created equal.

The wrong tool can leave your hair frizzy, uneven, or require multiple passes, leading to more heat damage and longer styling time.

In this guide, we compare the best hair straighteners for thick hair in Australia, including SAS, GHD, Dyson, and Cloud Nine—so you can choose the right tool for fast, smooth, salon-quality results.

What to Look for in a Hair Straightener for Thick Hair

Before choosing a straightener, it’s important to understand what actually works for thick hair:

High Heat (Essential)

Thick hair typically needs 180°C–230°C to straighten effectively in fewer passes.

Plate Type: Titanium vs Ceramic

• Titanium: Faster heat, smoother glide, best for thick or coarse hair

• Ceramic: Gentler, but often slower and requires multiple passes

👉 For thick hair, titanium is usually the better choice.

Plate Width

• Wide plates (1.5–2 inch): Ideal for thick or long hair

• Standard plates: Better for fine or short hair

Adjustable Temperature

Thick hair benefits from custom heat control, not fixed settings.

Even Heat Distribution

Reduces:

• Frizz

• Breakage

• Uneven results

Why SAS Is the Best Choice for Thick Hair

When it comes to thick hair, three things matter most: heat, coverage, and efficiency.

✔ One-Pass Straightening

Titanium plates glide through thick sections without snagging.

✔ Faster Styling Time

Wide plates allow you to cover more hair in each pass.

✔ Less Heat Damage

Fewer passes = less total heat exposure.

✔ Designed for Thick Hair

Unlike many competitors, SAS is built specifically to handle dense, coarse hair types.

Common Mistakes When Straightening Thick Hair

Avoid these:

❌ Using low heat → leads to repeated passes ❌ Using narrow plates → increases styling time

❌ Choosing fixed-temperature tools

❌ Using ceramic-only tools for very coarse hair
