weight of hair dryer?

The weight of the ghd Helio Hair dryer is 780g or just under 2 pounds at 1.7 pounds. I hope this was helpful information.

What attachments are included? Diffuser?

The only attachment it comes with is the bespoke contoured nozzle. We are in the works of creating a diffuser however this will be a sold separate item once it is released. I hope this answered your questions.

What is the correct wattage of the ghd helios hair dryer? i have read 1800, 1875 and 2200. can anyone verify?

Our ghd Helio Hair Dryer is 1875W. All of the Helio dyers have the same wattage. I hope this was the information you were looking for. Have a Good Hair Day!

How long is the warranty?

This is a great question I would be happy to assist you with today. Our ghd Helios Hair Dryer has a 2 year manufacture warranty. This is literally the best hair dryer I have ever used and I am a professional hair stylist. I have had many brands in the past which did not last or damaged hair even with protectant however, this one I have been using for months now in salon and it is amazing and dries the hair very quick giving it shine and beautiful movement without frizziness. I hope you love it as much as I do. I hope this answered your question today. Have a GOOD HAIR DAY!
