Siero 2% - Acido Ialuronico Puro

Smaller bottle, more expensive but it works

I like the original version better, bigger bottle, more product and less expensive. Feels like this new bottle is just a way to get you to pay more for less product. It works but I’m disappointed in the change

The hype is real

The hype is real! I’ve used this serum twice and my hair is so soft and so shine! It’s crazy how smooth it feels. Highly recommend it!

It’s ok

Good product but I didn’t notice anything spectacular. I really take a good care of my hair but I can live without this product. Too expensive and not big results

Worth every penny!

My hair started inexplicably falling out and breaking off last year, to the point that I got extensions just to cover up the damage. This stuff is almost like skin care for your hair--it is put on your roots first and then you extend to the ends. It makes your hair so soft, strong and manageable. While my hair hasn't fully grown back just yet, it is coming back thicker and healthier than ever.

A must have if you want glossy blonde hair

This is my second bottle of Blond Absolu Hyaluronic Acid Hair Serum. The fragrance is subtle and lovely. My hair has never felt so soft and frizz free.

Good product

Leaves hair very soft to the touch - absorbs nicely no sticky or oily residue

Not Just for Blondes, I'm Redheaded Proof :)

This stuff is pretty awesome! It took using it about 3 times before I noticed an improvement but it was worth the wait. It made my hair feel silky, soft, and smooth. I love that it felt weightless and wasn't sticky or gummy feeling like other serums I've used. My only wish is that the bottle was bigger. I have hair down to my butt and it takes about 7-10 pumps to get enough for all my hair and so the bottle probably isn't going to last as long as I'd hoped. But bottle size aside, I think this is my new favorite serum and definitely one I'll be recommending. Oh and I'm redhead by the way, so even if you're not blonde it's worth trying.

Maybe?

Very torn about this product -- it is super expensive especially if you are using 10 or more pumps!! The bottle doe snot even contain enough product for me to make an informed decision. My bottle is almost done and I have used it 4 times. Seems like it might be helping with dryness but, again, not enough applications to accurately tell.

Well worth purchasing

Absolutely love this product. I have my hairdresser apply it after blonde colour application & my hair feels strong & looks shiny. I use it myself every couple of weeks & can see & feel an immediate improvement each time.

Did nothing to enhance my hair

I was hoping this product would be as awesome as other Kerastase Blond Absolute oils and hair treatments -all excellent!. But I was quite disappointed by this 2%, hyaluronic acid product. Idid very little to add shine or enhance my hair’s condition in any way. Would not recommebdAfter applying to towel dried hair, ascdieexted, I

not just for blondes!

love this stuff. I don't have blonde hair but my stylist recommended this because my hair is dry. I have medium length fine virgin hair, I use three to five pumps of this on clean damp hair then I follow up with the nutritive thermique to seal it in. my hair is so shiny, soft and hydrated.

So gratifying

Did not have high expectations (and have rotated more Kerastase products out of my hair care routine lately) but this one surprised me. It seems weightless, not sticky, greasy or oily after applying. It immediately absorbed into my hair and left it looking and feeling hydrated and shiny for days until my next shampoo.
