Hey hey Denise
The difference between these heat protectants is that this Quick Dry is developed primarily for blow-drying and works especially well for thick hair, as it speeds up the drying process so that it’s quicker to blow-dry the hair
Cream Heat Spray works just as well for blow-drying as other heat tools, and besides protecting the hair from heat, it gives shine and repairing properties
So they have very different properties to help with different needs
Feel free to come back if you have more questions about these!
