Honest reviews



Icky, sticky, filmy and made my hair greasy by the end of the day. Smells good, not sure if it protects. My hair has never been dirtier!

Gluten Free Hair Care at it’s VERY BEST!!!

WOW! Did you know that Gluten is found in many different products that you use every day??? This may not matter to many, however, if you have an allergy to Gluten like I do, this information is of mega importance! Alterna is one of the very few companies who’s entire product line is Gluten Free! I started using their line and stopped using another line that contained gluten (unbeknownst to me) and guess what – My hair started growing like a weed!!! This spray is amazing!

Alterna Bamboo Smooth Anti- Breakage Thermal Protectant Spray for Unisex

I love Alterna hair products I don’t blow dry my hair but I do use a curling iron now and than I have noticed the damage it has done with this Thermal Protectant spray my hair has less breakage and is not dry .I do use other Alterna products also ,they are a little expensive but they really work .I will add this is more a cream than a spray therefore I put it on my hand than rub it in my hair so I can control the amount I use. I hope they never stop making these great products.

Has Dimethicone

Of course it will smooth your hair if it has dimethicone in it! I don’t know why I didn’t notice that before I purchased it. That being said, I did go ahead and try it. My hair did feel smooth and resilient even after flat-ironing. I would recommend using a very light hand with this product and holding it about 12 inches away from your hair. The product seems like a liquid, but when it “lands”: it turns into a gel–and you do not want to flat iron your hair with greasy gel on it.

Alterna Bamboo Thermal Sray – AWESOME TLC!

I love Alterna Bamboo Smooth Anti-Breakage Thermal Spray. It is awesome. It is so good to your hair. My hair used to break very easily. I use a flat iron on it and also occasional hot rollers. Also, I have highlights. My hair is naturally curly and can get very frizzy. I use this spray before blow drying my hair and again while flat ironing it or curling it. It doesn’t take a lot. It has no smell whatsoever so that’s good. After using this product, the condition of my hair is so good. I have also switched to DermOrganics shampoo and conditioning masque. This has all made a HUGE difference to my hair. I went from course, frizz, pouf hair, to smooth, silky hair. It’s like it’s not mine. But it IS! I love this and plan on buying it again and again.

Good Heat Protector

This is my second bottle of this and I really like it. I would have given 5 stars, but sometimes with my fine hair it moisturizes too much, and makes my hair look oily. Other than that, it seems to really protect my hair from the heat of blow drying and straightening. I like a more naturally made product and that is why I chose this.

I bought this from Sephora after reading reviews on their website, so I already was aware that if you spray this directly onto your hair, you might end up with a greasy, weighed-down ‘do. Other reviewers had mentioned that the product was excellent but the packaging (i.e. the nozzle) was not up to par. They resolved this by pumping a few squirts into their hand and applying by hand, so this is what I did and it worked like a charm. I only use about 5-6 small pumps on my shoulder-length, chemically-treated blonde hair to apply by hand, so I think this may extend the life of my product as well.The first time I used this, my hair had been feeling dry and the ends were becoming brittle from my everyday heat styling. I applied John Frieda Lux Volume Root Booster & Living Proof Full Thickening Mousse as I normally do, then applied this product BY HAND, as noted above (it smells AWESOME, btw!). I did a blow out with a hairdryer and a brush, did a little back-comb lift at the crown, then heat styled with a ceramic iron. When I was finished, I was WOWED. My hair looked SO shiny and healthy and was so soft, without loss of volume. It did not feel greasy at all. I was especially careful to coat this product at the ends of my hair, and they almost look completely repaired! I am amazed!I truly do not think my hair could look better and you would never know how many hair-damaging rituals I do to this head of hair by looking at it. I mean, you would think all this heat-styling (blow dry every other day but iron pretty much 6 days/week) as well as the highlighting would leave my hair a hot mess, right? Not anymore! This product is staying in my arsenal. I am hoping that my slow-to-grow locks will pick up the pace a little now that the heat styling isn’t doing daily damage!

So far I’m impressed

It isn’t sticky, definitely a lotion consistency. After reading the reviews, I went ahead and sprayed it directly on my hands and rub it in then apply it to my hair in sections. My hair was soft and I flat iron with ease. As for protection, I had split ends prior to using, so I had to clip them after i straighten my hair. The jury is still out on that, but I do feel it protects because my hair was smooth even with my raggedy ends. The smell is great too, not overwhelming at all.

So many others I like better – one that’s even cheaper. I wouldn’t buy this again. The spray pump doesn’t work well at all. The product doesn’t smell very good. I’ve had other oils (Kerastase) and thermal blowout sprays (Oribe, Miracle 7) that work so much better than this.

Great heat protection, doesn’t weigh hair down

I have super fine hair in a chin length bob and this really protects it from heat styling without weighing it down. I put about 6 squirts on before drying and don’t need to reapply before curling with a flat iron. Can’t recommend enough – it does a fantastic job and the bottle last for months.

I like Alterna products, but this one works okay, it feel like it leaves a film on my hair as I dry it and leaves my hair "poofy" even after it’s been flat ironed.

It’s Not A Spray

I don’t know if it actually helps with breakage but it does seem to make the hair soft. Also, it isn’t a spray, it’s a pump that pumps out a slightly thick product. I squirt this into my hand along with the Alterna Bamboo UV+ Fade Proof Fluide Spray (which also isn’t a spray!) and work it into the ends of my shoulder-length, salon-colored bob, then blow dry. I only use about 3 or 4 squirts of each and rub them together before applying and my hair seems silky and shiny. I only gave it 3 stars because I really don’t know for sure if it’s doing what it says it’s supposed to do.
