Amazing heat protection! Leaves hair super smooth and shiny.
I am really loving this L'Oréal Sleek It heat protectant spray. It does a fantastic job of protecting my hair from heat damage whenever I use my flat iron or blow dryer. The mist is super fine and even, so it doesn't weigh my hair down or leave any greasy or sticky residue. It keeps my hair incredibly smooth, frizz-free, and shiny all day long, even when it’s humid outside. It smells great too! If you style your hair with heat often, this is definitely a must-have to keep it health

I've tried many heat protectant sprays, but this one is by far my favorite.
Not only does it smell amazing, but it also does an excellent job of protecting my hair from heat damage. My hair stays soft, shiny, and smells great all day long. I've especially noticed that it helps protect my ends, which used to get dry from daily styling. I straighten my hair almost every day, and this heat protectant gives me confidence that I'm keeping it healthy. If you use a flat iron, curling iron, or blow dryer regularly, I definitely recommend giving this product a try.

My New Holy Grail
Wow!!!!! This stuff is absolutely amazing. I have thin, frizzy and wavy hair that's downright ugly. I've tried nearly every hair product on the market and must say this stuff is truly a miracle!!!!!!!!!! Flat iron, blow dry, expensive shampoos and conditioners, gels, mousses you name it I tried it. No matter how hard I tried, nothing worked. I almost gave up and then I found this. I simply wash my hair, towel or blow dry and spray on. When hair is dry I flat iron and/or blow dry and it comes out perfectly straight. NO FRIZZ. NONE. Nothing but sleek, shiny straight hair. An extra bonus is it smells nice and is very inexpensive. Annnnddddd it stays straight up to 3 days until I shampoo again..TRY IT LADIES....YOU WILL FALL IN LOVE!

Five stars — a must‑have for anyone who uses heat tools!
This heat protectant is phenomenal — easily one of the best drugstore styling products I’ve ever used. It deserves a full five stars for how well it smooths, protects, and keeps hair sleek all day. The spray is lightweight, non‑sticky, and evenly coats the hair without weighing it down. As soon as I use it, my flat iron glides effortlessly, and my hair comes out shiny, soft, and frizz‑free. Even in humidity, it helps my style stay smooth much longer than other heat protectants I’ve tried. I love that it doesn’t leave any residue or crunch, and it works beautifully on both damp and dry hair. The finish is clean, polished, and touchable — exactly what I want when I’m straightening or doing a sleek blowout. If you want salon‑quality results without the salon price, this product absolutely delivers.

My holy grail for years - finally leaving a review
I've been buying this L'Oreal Sleek It heat spray for years now and I finally decided to leave a review. After so long using it, I can honestly say it's a really good product. It protects my hair from the flat iron, keeps it sleek and frizz-free for days, and doesn't leave it sticky or heavy. I spray it on before I straighten and my hair stays straight and shiny much longer. I've tried other heat protectants but I always come back to this one. I totally recommend it - it's worth it.

Great for heat protectant
Love this product! I have very thick curly hair and this does a great job protecting my hair and keeping it shiny and fresh for even a week! It doesn't leave a residue and the smell is so fresh!

Great heat protector Great price
i loooooove this heat protector! i’ve repurchased many times. it 1000% helps straighten my hair quicker and more efficiently. I also saw a video where they tested the actual heat resistant and it worked very well! I love using it knowing it’s actually protecting my hair too.

Smooth, Sleek Hair
I’ve been really impressed with the L'Oréal Paris Advanced Hairstyle SLEEK product. The product has made a noticeable difference and it smooths everything down without making my hair feel heavy or greasy. What I like most is that it gives my hair a polished, sleek look while still feeling soft and natural. A small amount goes a long way. Make sure you keep an eye on the price because it really fluctuates quite a bit.

アインシュタインの稲田さんみたいな髪質の私ですが。。。
細くて量の多いくせ毛でオイル、セラム100種類以上使ってきて満足いくもの一つもなかった。ドライ後すぐ良くても翌朝起きると頭が爆発して、何して収まらくて結局お団子にする生活数10年。ダメもとで使ってみたら初めて満足できました!翌朝もサラサラ、雨でもサラサラ! 更年期や白髪で髪の毛がチリチリになった方も是非使ってみてほしい商品です。

Softest hair
Makes your hair sooo soft. I was blown away. I have used after washing and also to refresh my hair - just sprayed my hair with a lot and then used my shark flexstyle round brush (with a wee bit of tension - wrapping my hair around the brush) and it worked so well.
