This product works pretty well. I have been using it for over a year, and I have noticed that my hair isn't getting as damaged from using the blow dryer and the flat iron. The trick is to use it sparingly, otherwise it can weight down the hair. Just a light spritz is all that's needed. I have also noticed that my hair seems a bit shinier when I use it. I have been disappointed in some other Aveda products in the past, but I do like this one.

I don't think I gave this product enough time before I gave my first review, so I have now rewritten this review after several uses of the product! I now think it does add a protective coating to my hair. I also think it adds a little humidity resistance for the frizz factor after I Iron my hair.

I have been using this stuff for years and it does work. I decided to stop buying it once because I was trying not to spend so much time and money on beauty products and I seriously got split ends and breaks from blow drying my hair every day.
I spray only 3-4 pumps after showering and then comb it through with a wide tooth comb. It makes for a good detangler, too. Smells nice.

I seriously thought I accidentally purchased the brilliant hairspray instead of the heat protectant. It is like spraying aquanet on your hair from the 1980s if you actually put around 5-6 pumps on your hair. My hair feels like hay, is hard to brush, clumps together, etc. I am amazed that they keep this formulation as it is, as it has so much Specially Denatured Alcohol 40B or 40-2 in it to turn even the most luscious hair into the sahara. Seriously, SDA 40B/40-2 is cheap as dirt and since it is 90% what this product is, it should be around 2.00 a bottle.
Run, don't walk from this product. Is is $h!t as a product, you can do better with Suave or some other cheapy heat protectant. Aveda missed the mark and should be ashamed at the formulation of this product and how not only does it not do what it is supposed to do, it actually damages your hair more to use.

This spray is soooo SHIT it does nothing at all, no smell, no hydration, no shine, barely if at all detangle and even looks ugly. For this price I would expect something exeptional but I've never seen worst.
At least it does't harm hair...
Cheap gliss from schwarzkopf, l'oreal or even complete no-names from your local supermarket are way better

this does absolutely nothing. i could not figure out why my hair was so dry and then i finally put two and two together. honestly, i don't think this protects from "heat damage" at ALL. and that's not something you want to mess around with! nexxus all the way - lifesaver!

I really like this product, just not the price tag. I use it daily after i towel dry my hair before blow-drying. I like to use products that leaves a natural finish/ not sticky on my hair and the sales introduced this product to me. I spray this all over with my hand smoothing and distributing the product equally on my hair. I feel that my hair is not as dry when i use this prior to the blow dry session. I love the natural smell of the spray too!

I was looking for something to use on blowdryed hair before flat ironing. This is not it - it left my ends really dry. However, when used as directed on damp hair before blowdrying it provides great heat protection anyway and seems to work MUCH better. Will repurchase.

I like this protective spray. I couldn't really say if its working but I love the smell and I like to think its better to use it than to not considering what I put my hair through. I think its a good product but I bet there are better ones from other brands....I'm just loyal to Aveda.

Love this product. Been using it for several years and I swear it must be the only reason my hair is still in fabulous condition. between blowdrying and flat ironing, I put my hair through major war. This product saves it every time.

A couple of months ago I bought this product along with other Aveda products to address my dry, damaged hair. My hair is fine, naturally curly and highlighted and I use heat products so my work was really cut out for me. I found that the products were leaving my hair feeling rubbery and did not help the situation. I am no longer using these products (except for Aveda shampure because I like the smell so much). Switched to Kerastase Ciment Thermique and Pureology leave in conditioner and have been seeing great results.

All I find this product does is sort of detangle. I would suggest buying Johnson's and Johnson's No More Tangles instead. As far as preventing damage from heat products I don't think it works at all.

Smell is nice but it doesn't detangle. I have to use a separate detangler with this product.
If you only need this product for damage control/UV sun protectant it may be ok for you. It's not heavy and does not weigh hair down or make it oily.

This has the signature Aveda scent, so if you don't like it, you won't like this. lol
It leaves a nice shine in my hair without looking or feeling greasy. I only use it from time to time, so it'll last me a long time. It's a little on the expensive side, but I'm a sucker for the shine it leaves, so I'd probably buy it again if I ever ran out!

This is the nectar of the gods to me! For some reason, it is this stuff that really perks up my curls! Sometimes I wait too long before I put product on my hair and my ends get fuzzy. I spray this on the ends, and scrunch, and they look freshly cut. I dont find this product heavy at all for my abundant, fine hair. In fact, I use it rather liberally, wet or dry (unfortuantely for my pocketbook). This is THE hair product that I must ALWAYS have, end of discussion.

I bought this because I was told to use a thermal protectant since I frequently flat iron my curly AA hair. It has an earthy salon-y fragrance which isnt strong but lasts for a couple of days. Ive been using this for about 2 months. This product does seem to have some type of 'holding' element to it so to avoid applying too much I first spray 1-2 pumps on my hands and then distribute it through my hair which also allows for even distribution of product. Furthermore, this does take away some of my hair's shine. Im not sure if the product is actually 'protecting' my hair but it does help with detangling, however I dont think that I will repurchase but I will finish the bottle.Will posts updates if my feelings toward this product change.

Yes, this spray is a bit heavy. And yes, my hair's texture is medium-fine. But I actually like the stuff because it gives my strands a little weight. As long as I apply a TINY amount, I find that my hair has a little more heft--not in a greasy way, but in a "my-hairstyle-doesn't-blow-away-as-soon-as-I-leave-my-house" sort of way.
It seems to reduce heat damage, too.

LOVE THIS!! My hair used to constantly break when blow drying and curling. Now it has some defense. My brush glides through my hair and this product has significantly reduced hair snapping. The smell is absolutely amazing and I love that there aren't any chemical fragrances which would give me a rash. I also like the shine it provides. This product is a must have for me and I'd cry if it were ever discontinued.

The nicest aspect of this product is the fragerance, which Aveda is known for. I bought this product with the Dry Remedy Hair Care Line. The entire purchase - over $100 - has been very disappointing at best. I would suggest using the Grund protein and mositure spray, which has provides thermo-protection. I seriously doubt if I purchase anymore Aveda hair products again, since discovering the Grund hair care system and styling products. Specifically, I have used drug store heat protecting products, which worked similiarly, so unless you love the fragerance and/or are loyal to Aveada, I would suggest trying Grund.

I'm very disapointed.
I didn't use it long enough to see if it protected my hair well enough from heat but I trule feel like it made it worst. It has some hairspray ingredients so if you're looking for a simply protectant like I was this isn't it.
As I was drying my hair the hairspray took and made my hair sticky and hard to brush through which caused breakage (urrrr).
I always spray on protectant before I straighten too so I tried with this but despite the claim it really shouldn't be used on dry hair because it just wets it down again, makes it sticky and makes it singe when using irons.
In addition it did nothing to soften my hair or make it feel healthier and the package is leaky (it leaves a sticky film all over my fingers as I spray). I'm very disapointed especially considering I spent money on it that would have better been invested in trying Kerastase earlier and becoming a convert.
