Thermal Setting Spray – Heat Protecting, 8.5 oz | Strengthens Hair, Guards Against Heat Styling Up to 450°, Hair Spray, Vegan, Paraben-Free

I love this spray! It helps keep my hair protected from heat and the split ends away. Its lightweight and does not weigh my hair down. It hardly has a fragrance. It keeps my hair soft. I spray it on whenever I need to touch up and tighten my curls again so it works well for that too.

Love this spray! I went to Aveda for esthetician school and they did an Instagram video comparing all the heat protecting sprays and creams and this was one of the number ones. I love it because of the soothing smell and it makes my hair so soft. My curls love it too!

I bought this because the reviews were great. It did have a pleasant smell albeit very light and hardly noticeable. The ends of my hair did hold the curl a bit longer than with out product but not much longer. It had a bit tacky, dry caked on feeling. It’s kinda MEH!🤷‍♀️Expensive product for not much benifit.

My fave thermal spray, holds my girls for days.

This spray holds without causing the hair to look stiff.

I really wanted to like this product based on many reviews but it wasn't a fit for me. I am starting to grow my hair longer (past shoulder length) and use heat styling most days. I tried spraying this in my (fine) hair for the first use (probably 4 sprays) and then brushed it through. My hair felt dry and crunchy after styling. I will admit it held curls well! Since then I have tried just spraying it in my hands (2 x) and running my fingers through my hair. Despite this it still has the same effect. I can even see residue in my hair sometimes. It basically feels like high hold hairspray to me. It does smell nice, but the smell doesn't really linger.

This BIOLAGE Thermal Active Spray has become a must-have in my heat styling routine. I use it every time I style my hair with my curling wand set, and the results speak for themselves — more texture, more volume, and no sticky or crunchy residue. I have layered, wavy hair, and this spray gives it just the right amount of grip and body to help curls hold their shape, especially when I’m using different wand attachments. It also leaves my hair feeling soft and touchable, which is hard to find in a heat protectant that also boosts volume. It has a light, clean scent that doesn't overpower, and I love that it's paraben-free and vegan — those things matter to me when I'm choosing products I use regularly. Plus, the bottle lasts a long time even with frequent use. Pro tip: Spray it lightly section by section before curling — you’ll notice better definition, especially on layered hair. Highly recommend this if you heat-style your hair and want protection and performance in one product.

Love this hair spray!! Just takes small amount!

Uso muy poquita cantidad en relación a cómo estaba acostumbrada con otros protectores térmicos, porque si no mi cabello se enreda en el cepillo cuando lo seco con secadora.

This is the best one I have found on the market so far

This product is a game changer for me! It won't be for everyone though. My hair has been thinning over the last 10+ years and I've tried a plethora of different products to help thicken, volumize my hair. At its current state, my hair cannot handle any oil based heat protector. I tried one highly recommended brand and it made my already fine and thin hair so limp and lifeless. So then I decided to try Biolage heat protectant spray as I was intrigued that it also volumizes. It worked wonders for me! It created texture, volume and a thicker feel. I know most people want a soft feel but not me as soft equals lifeless for my hair so I'll take the rougher texture to get the volume. The spray is a bit sticky so beware of that but for those with hair like mine, it really helped!

Definitely does protect and increase volume and hold. Don’t know why they say it’s unscented though. It does have a scent. Smells like all the other products in that line.

I was hopping this was going to work good on dry hair before using a straightener but it makes my hair feel rough and sticky I haven’t used it on damp hair yet I usually let my hair air dry then use this when I straighten my hair not the best product for me I will keep looking for something else that works good on dry hair prior to using hot tools , I don’t notice much smell either it’s nice to have a product that has a nice scent but this one doesn’t .
