Heat Protective Hair Spray Schwarzkopf Professional Osis+ Flatliner Heat Protection Spray

Convenient sprayer, I have just started using the product and find it comfortable to use. As for its thermal protection function, I cannot comment on it yet.

The best thermal protection available!

Excellent thermal protection, it performs its function excellently!

This is an excellent heat protectant, especially for use with a flat iron or curling iron. This spray has a strong hold, so there is no need to pour half the bottle and then wonder why your hair feels stiff. It should be sprayed lightly, like a veil.

My favorite heat protectant! I am completely satisfied with this product.

It didn't work out; my hair felt extremely rough afterward.

I have thin, dyed hair, and I really didn't like this spray at all. The dispenser is very inconvenient. It does not perform its functions.

I did not notice any changes in my hair when using this product. The dispenser turned out to be faulty as it leaks a lot of liquid when sprayed onto the hands, which prevents proper distribution. Additionally, half of the heat protectant simply spills out into nowhere.

I have tried various products, but I have settled on this one. I have been using it for 4 years now and I am extremely satisfied.

The thermal protection is excellent.

After using the spray, my hair feels soft, but it tends to become static.

Good thermal protection, I am buying it for the second time. It does not weigh down the hair and does not leave an unpleasant odor.

The heat protection is good, it leaves my hair shiny and gives a great feeling. However, I can't really say how well it protects from the blow dryer as I'm not knowledgeable about that. But overall, I recommend it.

In principle, this thermal protectant is great. It makes my hair shiny. I'm buying it for the second time.

Good spray, has styling properties, slightly sticky. It can dry out the hair, like all alcohol-based heat protectants. I use it after moisturizing leave-in conditioners. I blow dry my hair and it works for me. The scent is ordinary, not sharp. Beautiful metallic bottle.

I liked it.

I have thin hair, but this spray worked perfectly for me. It even had a better effect than the CHI brand. Of course, results may vary for everyone, but after using it, my hair becomes smoother, tangle-free, and less prone to static.

I didn't see any effect at all. My hair became extremely unruly after using it. Moreover, it often made my hair staticky.

The thermal protection is excellent. I bought it based on my hairdresser's recommendation. After several uses, my hair became softer and more manageable. It doesn't get frizzy in humid weather, even though I used to have a problem with that before. I use it before using the hairdryer and straightener. I also apply it to the ends before going outside in freezing temperatures.

The hair becomes very stiff after using it.

I didn't like the spray at all. I have long hair, and it acts like hair spray, not allowing me to comb it and sticking it together near the roots. I tried it once, but I don't want to use it anymore.

I can't understand where this spray gets so many good reviews from. The spray is like water. Moreover, it made my hair tangled. I have never faced such a problem before.

This is the best hair spray, absolutely the best. It makes my hair straight, shiny, and smooth, and it smells amazing. I used it before blow-drying and after straightening with a low temperature, and it worked perfectly. Give it a try, you won't regret it.

The spray works perfectly, giving a 100% result. It doesn't weigh down or stick the hair. I have been using it for 2 years already, and I am pleased with the product.

"This is already my second jar. This cool heat protectant is not worth all the money in the world, but it's the one that actually works. Many stylists recommend it."

Good thermal protection.

I ordered a heat protectant for my hair. Overall, the spray is good, but it doesn't provide a strong hold on the hair. It feels like I sprayed it with hairspray.

I bought this flat iron for my daughter, and she uses it every day. She says that her hair is even straighter after using the flat iron, and it doesn't curl up in humid weather. I noticed the label on the back and found out that it not only provides heat protection but also contains a serum for smoothing, two products in one. It really works great. I learned about this spray from a skilled hairstylist during a hairstyling training session in Kiev.

No scent, no hold, doesn't weigh down. The ingredients are good. But it feels like water-watery. I believe in the ingredients, that's why I use it!

This is an amazing product. It provides excellent protection without any odor. It also comes in a large volume.

I have been ordering this product for the fourth time now, and it does a great job protecting against high temperatures. Initially, I wasn't fond of the spray as it does tend to make the hair a bit "sticky" and gives the appearance of dry ends. However, if you apply some oil on top of the spray, the result is absolutely amazing.

I didn't understand this product at all. My hair became stiff and difficult to comb after using this spray. It didn't live up to my expectations, especially considering the price. I could have bought two heat protectants that were much better for the same amount of money.

Good

I was just about to place an order, added items to my Cart at a certain price, and then within 5 minutes, the price doubled.

I have been using this product for many years. It suits me well. After using this spray, my hair feels a bit stiff, but it is actually suitable for my fluffy hair. The heat protection even helps to hold my curls when using a flat iron. I have tried many heat protection sprays, but I always come back to this one.

I really liked this product. It made my hair soft and smooth without damaging them. I will definitely buy it again.

Excellent spray. I have been using it for many years. It makes hair smooth and silky. Thank you makeup for the fast delivery and pleasant surprise ))) There was also a beautiful cosmetic bag in the package.

I ordered it for the first time. It doesn't weigh down or make my hair greasy. My hair doesn't get frizzy and it has become easier to style them.

My favorite heat protection product, but I'm waiting for the opportunity to order it from Europe. Even with a discount, the price here is quite high.

This is my first heat protection product, and I hope it will work. Based on my experience, it's great - it doesn't make my hair greasy or weigh it down.

This is a great product that leaves my hair well-nourished and smooth.

This product is terrible. It's the first time I write a review here. It doesn't provide any smoothness, it just makes everything sticky. It's not suitable for fluffy hair or dry hair.

The straightening effect is completely absent; it feels like only girls with straight hair wrote positive reviews. In humid weather, the hair still becomes frizzy, just like without using the product. I hope it at least works as a heat protectant.

This serum is excellent for hair straightening. After applying it, the hair becomes smooth, silky, does not frizz, and looks well-groomed.

There is no protection against tampering! The packaging is different.

Honestly, I was expecting more. I bought this product based on positive reviews, thinking it could work as a heat protectant. However, many people mentioned that it also helps with frizz (especially in humid weather), but unfortunately, it didn't help my hair at all. I'm really disappointed because that was the main reason I bought it, as I already have another heat protectant.

This product is amazing. It not only smooths out my hair but also protects it from moisture, which was my biggest problem. Even with a slight mist outside, my hair stays fluffy and voluminous. With this product, I don't have to worry about getting caught in the rain. Of course, my hairstyle might get a bit ruined, but it doesn't frizz or tangle. Thank you, makeup, for your great work!

I came across this product at the hair salon and couldn't resist buying it for myself. It is an excellent tool to use with a straightening iron, and it is both affordable and effective!

I was recommended this product when I bought a flat iron. My hairstylist says that my hair hasn't been damaged (I was very afraid of burning it, I have been using the flat iron regularly for two years now). I ordered the product for the second time (it lasts for a year). I am very satisfied.

This is a really cool product, but it's important to understand that it works best when used together with a flat iron. Just spraying and drying alone won't straighten anything. However, as a heat protectant, it's really great. I bought it based on my hairstylist's recommendation.
