BaByliss Pro 32mm Curling Iron Explained: A UK Buyer's Guide

A BaByliss Pro 32mm curling iron is a professional-style large-barrel tong aimed at people who style often and want faster heat recovery. The 32mm barrel makes loose, polished waves rather than tight curls, and the “Pro” badge mainly signals a higher top temperature and steadier heat, useful if your hair is thick or long. For a full head of heavy hair, though, a single round barrel is still slow going, and that is worth knowing before you buy.

Does thick, long hair actually need the Pro version?

If your hair is thick and long, you already know a standard iron can cool down halfway through a head and leave the last sections limp. That is where a Pro-style tool earns its price: it recovers heat between sections, so wave number twenty looks like wave number one. What it does not change is the physics of a round barrel, you are still wrapping and holding each section by hand.

When one wash-and-style already eats an hour, the honest question is whether more heat or a different tool shape saves you more time. Higher heat sets thick hair faster; a wider pressing plate sets more hair at once.

Heat settings that hold on thick hair

• Fine or colour-treated lengths: stay below 180C, even on a “pro” tool.
• Medium hair: 180–200C is usually the sweet spot.
• Thick, coarse or resistant hair: 200–220C, in small sections.

Always start at the lower end and step up only if the wave falls out. Prepping with a mousse and letting each section cool before you release it does more for longevity on thick hair than sheer temperature.

Where a 32mm iron slows you down

The trade-off with any 32mm curling iron on thick hair is time. Small sections are non-negotiable, because a thick section will not heat through evenly, so a whole head can take 30–45 minutes. A “Pro” label does not shorten that; it only keeps the barrel hot while you work. If speed on a heavy head of hair is your priority, a clamp-style waver that presses a wider ribbon of hair is the bigger upgrade.

The faster route for a full head

If you want big waves that survive till the next wash without the 45-minute session, the FrenchWave 32mm Mermaid Wave Curler presses a continuous S-wave in one pass. Its tourmaline-ceramic barrels reach up to 220C for thick hair, it is £40.15 (RRP £60.22), and it ships free next-day across the UK with a 12-month warranty.

Frequently Asked Questions

Is a BaByliss Pro 32mm curling iron good for thick hair?

A 32mm barrel with a high heat setting can shape thick hair, but you will need small sections and patience. Thick, long hair often sets faster with a dedicated waver that presses a wider section at once.

What temperature should thick hair use on a 32mm curling iron?

Thick or coarse hair usually needs 200 to 220C to set, while fine hair should stay below 180C. Always start lower and increase only if the wave does not hold.

How long do waves last on thick hair?

On thick hair, waves can drop within a few hours if the hair is heavy or freshly washed. Prepping with mousse and letting each section cool before you release it helps the shape last into the evening.

Is the Pro version worth it over a standard 32mm iron?

Pro-style irons tend to recover heat faster and hold a steadier temperature, which matters on a full head of thick hair. For occasional styling, a standard tool or a waver may be enough.
