FAQs
Is Diffon Pro Curl clinically tested?
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
