Does this work well on curly frizzy hair?

Yes!! And I’ve tried my fair share of expensive products. This is the one I prefer, and my second bottle. I live in south Florida, so quite familiar with frizz!

Does this contain any type of formaldehyde?

It does not appear so, but I am not an expert. Perhaps you should check with Nexxus directly.

How do you use the Nexxus serum? What are the directions to use the Nexxus ultralight smooth serum?Does it go on dry or wet hair?

This lightweight, cream serum forms an invisible, breathable barrier around each strand of hair to block out frizz & humidity for up to 72 hours of smooth, soft hair. The fast absorbing, premium nourishing formula disappears into the hair for a clean feel. The cream serum can be used on damp or dry hair as a third step in your wash day routine, or as a refresh in between washes. It can also help protect against heat styling. Pump a small amount into palm and spread evenly on hands. Apply to damp or dry hair, focusing on the mid-shaft and ends. Style as desired.

How does this compare to nexxus prep & protect spray?

I use them both. The spray helps detangle and the creme smooths
