Love this product. A great detangler and heat protector. Hair looks shinier.

Love this product. First of all I think it smells good. Then I’ve noticed how soft and hydrated my hair feels since using this. It’s a little pricey but if you’ve got the extra cash to spend, then worth it.

Works good

I’ve used this now about 3 times since I received it. It’s hard to tell but it seems to be protecting my hair. I use a flat iron on the 230 setting and my hair is staying shiny and still feels ok. No frizz and seems to last. I will update if I think I need to.

Love the smell and keeps your hair nice and moisturized and protected from heat

I’ve been using the Nexxus Heat Defense Spray for a few weeks now, and I’m really impressed with how well it works. It provides excellent protection against heat damage, whether I’m using a blow dryer, flat iron, or curling iron. The spray goes on light and doesn’t leave my hair feeling greasy or weighed down. It also adds a nice shine and keeps my hair feeling soft and smooth all day. I love that it protects without compromising the style, and my hair feels healthier even after frequent styling. Definitely a staple in my hair care routine!

I use before blow drying to prevent heat damage. It seems to do the job.
