I actually really like this product to use for a blow-out.
I have naturally very curly, dry, long, color treated hair. I use Wen to wash my hair and then put a dime size amount of this throughout my hair after i step out of the shower. I then put my hair up and let it air dry for a varied amount of time (totally depends on how long I have, anything from 1/2 hour to 5 full hours). The product doesn't leave too much film behind and doesnt get too stiff (you can tell you have something in there, but once you add heat it melts into hair nicely).
I then use a barrel brush and blow dry my hair. When i use this i don't need to straighten or use any other product, maybe just a finishing spray. Hair is SOFT, something I rarely get with just a dryer.
I would not use this to air dry my hair, its really great as a blow dry style product, to get a smoother and softer blow out and protect the hair from heat damage.
I will repurchase and highly recommend for curly girls who like to blowout straight and need extra moitsure and protection.
