Diffon Pro Curl Curly Hair Dryer

Diffon Pro Curl is an All-in-One dryer and diffuser designed specifically for waves, curls and coils — rather than a general-purpose hairdryer with a separate diffuser attachment.

Its integrated design brings the motor, airflow, temperature control and diffuser together in one tool designed around curly hair.

Pro Curl adds a high-performance digital motor, 21 speed and temperature combinations, Scalp&Care, cold airflow and two professional diffuser designs, giving you more control over how you dry and style your curls.

Yes. Diffon Pro Curl was evaluated in an independent clinical study of 40 women with curly hair conducted by Bio Basic Europe and the CDC Dermo-Clinical Research Institute in Milan.

Compared with a traditional Bellissima hairdryer and diffuser, the study assessed six hair benefits: frizz, curl definition, shine, softness, elasticity and volume. All six showed statistically significant improvement.¹

It has been independently tested against air-drying.

In a laboratory study conducted by Bio Basic Europe and the University of Pavia, human hair strands were put through eight wash-and-dry cycles, simulating one month of use. Hair dried with Diffon Pro Curl was compared with hair left to air-dry.

The study found no statistically significant difference in hair damage between the two groups.

Independently tested. As gentle as air-drying.³

Both are advanced All-in-One Diffon dryers designed for waves, curls and coils, but they offer different levels of control.

Diffon Supreme Ionic XL features a large XL diffuser bowl, Dual Ionic Technology, three temperature settings, two air speeds and an Ultra Gentle cooler setting. It is a strong choice for longer, thicker, frizz-prone or more demanding curls.

Diffon Pro Curl is Bellissima's most advanced Diffon, adding a high-performance digital motor, 21 speed and temperature combinations, Scalp&Care, cold airflow and two professional XL diffuser designs: Define & Sculpt and Bounce & Volume.

Choose Supreme Ionic XL if you want a larger integrated diffuser with added heat and airflow control. Choose Pro Curl if you want Bellissima's greatest level of customisation and styling control.

Choose the Diffon that best matches your hair, routine and travel needs.

Diffon Pro Curl — Bellissima's most advanced Diffon, with a digital motor, 21 speed and temperature combinations and two professional diffuser designs for the greatest level of control and customisation in the Diffon range.

Pro Curl includes two professional diffuser designs so you can tailor your drying to the result you want.

Define & Sculpt is designed for curl definition and shaping, helping you work with the natural pattern of your waves, curls or coils.

Bounce & Volume is designed when you want more lift, bounce and volume.

You can use either diffuser throughout your routine or switch between them depending on the result you want to create.

There is no single perfect setting for every curl. The best combination depends on your hair density, length, porosity and the result you want.

As a general starting point:

• Fine, delicate or heat-sensitive curls: start with lower temperature and airflow.
• Medium curls: begin in the middle of the range and adjust as needed.
• Thicker or denser curls: you may prefer more heat or airflow during the early stages of drying.
• Pixie diffusing: lower airflow can help minimise movement while curls sit in the diffuser.
• Hover diffusing: you can use more airflow because the diffuser is not directly cupping the curls.

Start gently and experiment. Pro Curl's 21 speed and temperature combinations are designed to let you personalise your routine rather than forcing every curl type to use the same settings.

Scalp&Care is a dedicated gentler drying option on Diffon Pro Curl.

It is useful when you want a lower-intensity way to dry around the scalp or when working with fine, very dry, delicate or heat-sensitive curls.

Combined with Pro Curl's wider range of temperature and airflow settings, it gives you more control over how much heat and airflow you use during different stages of your drying routine.

Diffon Pro Curl is designed for waves, curls and coils and gives you a wide range of temperature and airflow options so you can adapt your drying routine to your hair.

The independent clinical study included women with fine curly and medium-thick curly hair, and both groups showed improvement across the main clinical hair-benefit measures.¹

For fine, dry, coloured, permed or more delicate hair, start with gentler temperature and airflow settings or Scalp&Care and adjust according to how your hair responds.

Individual results will depend on your curl pattern, density, porosity, hair condition, products and drying technique.

No. Diffon Pro Curl is not dual voltage.

The Australian and New Zealand  Pro Curl model is designed for 240V electrical systems and should only be used where the local voltage is compatible.

If you regularly travel between countries with different voltage systems, Diffon Worldwide is the Bellissima model designed for international travel. It has dual-voltage capability and can be used across compatible 110–125V and 220–250V markets with the appropriate travel plug adapter.

Always check the local voltage and plug requirements before using any electrical hair tool internationally.
