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

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.

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

The thermal protection is excellent.

This product is excellent! It seems to even have a straightening effect. The spray bottle is convenient. I highly recommend it.

5 stars! My porous hair becomes smooth, like after using a flat iron. It doesn't weigh it down. I only regret not using this product earlier.

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.

The heat protectant 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 always have this problem.
I use it before using a hairdryer and straightener.
I also apply it to the ends before going outside in freezing temperatures.

The hair feels very stiff after using this product.

I really like this heat protectant, especially considering its price.

Absolutely pointless, just water. My hair looked like icicles after using it, I've never had such awful hair after blow-drying with this heat protectant. I used it twice and threw it away. I switched to the Real Shea heat protectant, which is amazing. My hair brushes through perfectly, shines, has volume, and it seems to dry faster as well.

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.

This product is odorless, does not cause any stiffness, and does not weigh down the hair. The ingredients are of good quality. However, it feels like using water on the hair. I trust the composition, which is why I continue to use it!

Amazing product. Provides excellent protection. Odorless. Large volume.

"The best heat protection, the jar is almost empty, I want to get another one soon."

I really liked the heat protectant, and I found out from a friend who is a hairstylist that the ingredients are good. Normally, my hair gets tangled after washing, but after using this spray, it is easy to comb through!

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.

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 biting.

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

I have been buying this product multiple times, and it provides excellent heat protection. After using it, my hair becomes shiny and doesn't get frizzy.

The effect is really cool! After using it, my hair becomes smooth and doesn't get frizzy. I really like it!

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!

I was recommended this product when I bought a straightener. My hairstylist says that my hair hasn't been damaged (I was very afraid of burning it, I've been using the straightener 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 only works to its full potential when paired with a flat iron. Just spraying and blow-drying won't straighten anything. However, as a heat protectant, it's really great. I bought it based on my stylist's recommendation.

If you are still thinking, then go ahead and buy it. It straightens hair amazingly well and also reduces static. Just run the comb through a couple of times and they will be perfectly straight. However, I'm not sure if it will work for all hair types. (I have straight hair)

I have been using this hair mask for many years. It is perfect if you blow dry, style, and/or use a straightener on your hair, but be careful not to overdo it with the amount. I am satisfied with it, so I keep buying it.
