I have experienced thin and fine hair for decades. Have been using the Dyson hair dryer and air wrap for two to three months. I would like to know how using the Dyson hair dryer and air wrap have improved my hair quality including thickness, clean feel and texture.
The appearance of my hair is much improved in the mornings. I took my air wrap and dryer to my beautician to try. The beauticians in the shop now have the Dyson products.
My beautician thinks the lower heat and not using a hot iron every day has helped as well.  

What is the science of Dyson hair products that improves hair quality so much.

I also have Dyson vacuums and have gifted vacuums. They are awesome. Jury is out on my Dyson robo vacuum. Not sure about it yet.
