What the gurus are saying

This heat protectant earns praise for smoothing frizz and adding shine without weighing hair down, making it a reliable choice for anyone doing frequent heat styling. Most gurus call it great across all hair types, though those with fine hair may want to use it sparingly, as it can feel a touch heavy if applied generously. The lightweight formula and minimal scent make it practical for daily use.

"I only needed to restock three items. [...] Two of the three products I needed to restock were both dry heat sprays. I have recently used up just about every dry heat spray that I had, so it was good timing to get these at a discount. Both of these are in my top three favorite dry heat protectants of all time. First, of course, the Living Proof Perfect Hair Day Heat Styling Spray."

"Living Proof Perfect Hair Day Heat Styling Spray, but I just did a giant dry aerosol heat protectant showdown."

"There is full agreement with the smoothing claim, one of the biggest reasons this has always been loved so much, making hair feel super soft and smooth without weighing it down. [...] It gives a bit of a volume boost that was not fully noticed until comparing it to the other products. Hair continues to look and feel great the entire time it is in, up until the next wash, making this the absolute favorite dry aerosol heat protectant and the winner of the showdown."

What's Really Worth Buying During Amazon Prime Big Deal Days?

"This is my absolute favorite dry heat protectant, something I always reach for when I'm reheat styling my hair when it's dry, like a couple days after washing. [...] Out of every dry aerosol heat protectant I've tried, this by far makes my hair the softest and smoothest, and the heat protection is up to 450 degrees. This is just the best, I love it."

Amazon Prime Day Recommendations! Amazon Prime Day Sale 2024

"And from Living Proof, their Perfect Hair Day Heat Styling Spray is my absolute favorite aerosol heat protectant. It gives you up to 450 degrees of heat protection, but it also makes my hair so soft and smooth, which is not super easy to find in a dry aerosol mist. I have definitely tried mists like this [...] that make my hair feel dry and kind of rough, and they get tangled more easily. This conditions my hair while also applying that heat protection in aerosol form."

"It's super lightweight and doesn't contribute to that buildup feeling whatsoever, but [...] despite being an aerosol it actually makes my hair feel so soft. I would highly recommend this for heat protection, I just cannot say enough good things."

"I have been using [...] the Living Proof Perfect Hair Day Heat Styling Spray non-stop, it's an aerosol heat protectant and I think it's officially my favorite aerosol heat protectant I've ever tried. [...] It's my new favorite way to apply heat protection on dry hair and it makes my hair so smooth. Some aerosol sprays I've tried make my hair look and feel a little dry and tangly, but that never happens to me with this one."

The BEST Haircare of 2023!

"The reason it stands out to me so much is because this makes my hair feel so so soft and smooth, and that's definitely not always the case with a dry aerosol spray, sometimes they can make your hair feel a little dry and a little frizzy, and that's not the case for this product at all. It really does make my hair feel so nice plus I'm getting that lightweight heat protection, which is amazing."

"I've been trying the new heat protectant spray now. I have to go very light with this because it's a little heavy on my fine hair. If you have a heat protectant spray that's very light on the scent, which this is, let me know down in the comments. I'm looking for one. So far this is my favorite. Usually they do sit a little bit heavy on my hair and weigh them down."
