BaByliss Platinum Diamond Hair Dryer & Diffuser - Professional 2300W Blow Dryer with AC Motor, Ionic Frizz-Control, 3 Heat & 2 Speed Settings, Diamond, 6490DU

The BaByliss Platinum Diamond is a 2300W dryer with an AC motor, which is the type you find in salon-grade dryers. Most consumer dryers use DC motors. The difference: AC motors are more powerful, last longer, but weigh more. 4,600+ reviews at 4.6 stars. Comes with a diffuser.

AC motor vs DC motor

This is the main thing that separates the Platinum Diamond from BaByliss's cheaper models. AC motors spin faster and push more air, which means faster drying. They also tend to last longer under heavy use. The trade-off is weight and price. Our hair dryer AC vs DC motor article explains the engineering differences properly.

If you dry your hair daily and want something that'll last years of hard use, the AC motor matters. If you dry twice a week, you probably won't notice.

Diamond ceramic

BaByliss infuse the heating element with diamond particles, which they say improves heat distribution and adds shine. Marketing? Partly. But the ceramic element does distribute heat more evenly than a bare metal one, and the ionic output reduces frizz. Whether the diamond specifically does anything measurable is harder to prove.

Our what is ionic hair dryer article covers the ionic side. For the full tech comparison, our best professional hair dryer guide puts this alongside salon models.

The diffuser

Large diffuser included, designed for curly and wavy hair. Bigger than the diffusers on cheaper BaByliss models. If curly hair is your main concern, our best hair dryer for curly hair roundup has dedicated options. For diffuser technique, our how to use a hair dryer diffuser guide walks through it.

Settings

Three heat, two speed, cool shot. Same control layout as the Midnight Luxe. Nothing unusual here but nothing missing either.

Who it's for

People who want the AC motor durability without jumping to ghd or Dyson prices. It sits in the mid-upper range: more than a Remington, less than a ghd Helios. The diffuser inclusion makes it a better choice for curly hair than the Midnight Luxe, which doesn't come with one.
