Review: I have very long naturally curly gray hair and I have used a wide variety of products. This product is light on the hair and doesn’t feel oily. It leaves my hair feeling natural and doesn’t weigh my curls down. Most anti-frizz products can’t be used on dry hair, but a section of my hair started to frizz at the end of the day and I took a dab and rubbed the strand of hair between my hands and it worked great! A little of this product goes a long way. The fragrance is nice too. No break outs on scalp or skin. Hope this helps all the frizzies out there :)
Review: I have tried everything to tame my wavy frizzy hair from humidity. This cream is the only thing that works for me! My hair stays straight and frizz free for 2 full days until my next wash. Highly recommend

## Questions & Answers

**Q: Does this work well on curly frizzy hair?**
A: 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!

**Q: Does this contain any type of formaldehyde?**
A: It does not appear so, but I am not an expert. Perhaps you should check with Nexxus directly.

**Q: 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?**
A: 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.

**Q: How does this compare to nexxus  prep & protect spray?**
A: I use them both.  The spray helps detangle and the creme smooths

### ⭐⭐⭐⭐⭐ Review
*by J***. on 7 January 2026*

I have natural curly hair and we live in the south so the humidity during the summer is awful and makes my hair frizzy. Purchased this product bc a friend told me about it. I really like it. It smells so good. Very light so it doesn’t weigh down my hair and it definitely helps my curls to not be so frizzy.Will definitely continue to use this product.
