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

This is truly the coolest thermal protection product. I am impressed. It's worth the money. And this lightweight fixation is exactly what I needed. No need to use a bunch of products to achieve the same result.

So far, this is the best heat protectant. It also provides great hold - my curls stay in place for 2 days effortlessly. The metal canister is a nice touch, and the spray nozzle works well.

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

The best heat protection!

Excellent heat protection, it performs its function superbly well!

This thermal protector is great, especially for use with an iron or curling iron. It is a spray with a firm hold, so there is no need to pour half the bottle and then wonder why the hair feels stiff. You should spray it lightly, like a veil.

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

It didn't work out, my hair became very stiff after using it.

I have thin colored hair, and I didn't like this spray at all. The dispenser is very inconvenient. It doesn't 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 sprays out a lot of liquid onto my hands, making it impossible to distribute it properly. Additionally, half of the heat protectant spills out wastefully.

Great product! I have purchased it multiple times and I am always satisfied with the quality. I use it before blow-drying with a straightener. It leaves my hair extremely smooth and shiny. I highly recommend it!

The product is decent and performs its function well. However, it turns soft hair into stiff hair, which becomes very tangled, unruly, and difficult to style. It works better on already stiff hair. However, I will not purchase it again.

The hair feels soft after using the spray, but it tends to get frizzy and static.

Good thermal protection, I am purchasing it for the second time. It doesn't weigh down my hair and doesn't leave any unpleasant odor.

The heat protection is good, it leaves the hair shiny and gives a pleasant sensation. I can't say for sure how well it actually protects from the hairdryer, as I'm not knowledgeable about that. But overall, I recommend it.

In principle, this thermal protection is great, and my hair looks shiny after using it. I'm purchasing it for the second time now.

This is a good spray with styling properties, although it can feel slightly sticky. Like any other alcohol-based heat protectant, it may dry out the hair. I use it after using moisturizing leave-in treatments. It works well for me when blow-drying my hair. The scent is ordinary and not overpowering. The beautiful bottle is made of metal.

I liked it.

I have thin hair, but the spray worked perfectly for me. It even had a better effect than CHI. Of course, everyone's experience may vary, but after using it, my hair becomes smoother, tangles less, and is not as prone to static.

I didn't see any effect at all. My hair is very unruly after using it. Plus, it often becomes static.

I really liked it.

I purchased it for 110 UAH on a website in Prague. There is absolutely no smell to it. Plus, it is very convenient.

I didn't like the spray at all. I have long hair, and it acts like hair spray, making it difficult to comb and sticking near the roots. I tried it once and I don't want to use it again.

I can't understand why this spray has so many good reviews. The spray is like water. Moreover, it even started tangling my hair. I've never had this problem before.

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

The spray works perfectly. It doesn't weigh down or make the hair sticky. I have been using it for 2 years and I am satisfied 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 hair heat protectant. Overall, the spray is good, but it doesn't provide a strong hold on the hair. It feels like I sprayed hairspray on them.

I bought this straightener for my daughter, and she uses it every day. She says that her hair looks even sleeker after using it, and it doesn't curl up in humid weather. I noticed the label on the back and it turns out that it's not just a heat protectant, but also a serum for smoothing, two in one. It really works great. I learned about this spray from a skilled hairstylist during a hairstyling training session in Kyiv.

Great heat protection, hair feels smooth and shiny, looks hydrated.

I bought it as a gift, and it was delivered from the EU. When I transferred the product from its original packaging to the gift bag, almost everything spilled. I called customer service and they said that the packaging arrived intact, so it's not their problem. I don't understand how they can package it like this. Thank you for ruining my mood and wasting 300 UAH.

I have ordered this product for the fourth time now, as it provides good protection against high temperatures. Initially, I was not impressed with the spray, as it tends to slightly "stick" the hair together and give the appearance of dry ends. However, if I apply oil on top of the spray, the result is truly amazing.

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

Good product

I was just about to place an order, added items to my cart at a certain price, but after 5 minutes, the price doubled.

I have been using this product for many years. It suits me well. After using this spray, my hair becomes slightly stiff, but it actually works well for my fluffy hair. The heat protection even holds my curls when I use a straightener. I have tried many heat protection sprays, but I always come back to this one.

I really liked this product. It left my hair feeling soft and smooth without any damage. I will definitely purchase it again.

Great spray. I have been using it for many years. It makes my hair smooth and silky. Thanks to 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 grease my hair. My hair doesn't get frizzy and it has become easier to style them.

Best heat protection. The smell remains the same as before and so does the effect.

I have been using this product for a year, and I will continue using it in the future! My hair has noticeably improved with this heat protection. I even used it during the summer when I didn't use a hairdryer or curling iron. I absolutely love this spray! The price is definitely worth the quality, 100%!

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

"Terrible product. This is my first time writing a review here. It does not provide any smoothness and instead makes everything sticky. It is 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 becomes frizzy just like without the product. I hope it at least works as a heat protectant.

This serum is excellent for hair straightening. After application, 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 might work as a heat protectant. However, many people mentioned that it also helps with frizz (especially in humid weather), but unfortunately, it doesn't help my hair at all. It's a pity because that was the main reason I purchased it, as I already have another heat protectant.

Great product. It not only evens out but also protects from moisture, which was my biggest problem. A little bit of mist outside and I turn into a fluffy poodle. With this product, I'm not afraid to even go out in the rain. Of course, my hairstyle gets ruined, but it doesn't get frizzy or tangled. Thank you, makeup, for your work!

I saw this product at the hair salon and couldn't resist buying it for myself. It is an amazing product to use with a flat iron, and it is both affordable and effective!
