Oh, how I love this. Kerastase has been around for so long - my Mum was a hairdresser in the 1970's and she remembers this being a very elite line of products and nothing has changed since then.

I currently have very damaged hair. In the last four years I have been switching my hair from platinum blonde to brown; receiving a full-head of foils every month for a year consecutively and straightening once every three days. As a result my hair has thinned dramatically and I have had to cut it very short. My hair is at its worst and my hairdresser says that if I put bleach on my hair one more time, it will all snap off, 100%. Now my hair is back to brown (my natural colour) and I'm getting regular cuts and growing it out again.

This is where Kerastase masquintense comes into play. I've been researching the best products to use on my hair, and this one came up. I can tell you after only two uses of this stuff that it is helping my hair unlike anything else ever has. What I do is I wash my hair with my regular shampoo and then put the masquintense ALL over my hair. I use a fairly large amount and rub it into my scalp and all through the rough, brittle areas of my hair. I put on a disposable plastic shower cap and leave it in for a few hours. Some people say that conditioner works instantly and there's no need to wait, but I'm not sure if I agree with that. After the four hours I hop in the shower and wash it all out. There is no need to apply a regular conditioner after this because this acts as a conditioner as well as a mask. When it's washed out, I let my hair air-dry.

Oh my god! The first time I used this I couldn't believe the condition of my hair. It was so smooth, soft, silky and shiny. It feels as though nothing as little as a hair dryer has ever been in contact with my hair, let alone bleach, peroxide and over 270 degrees heat which I have been exposing it to! I remember going to bed and feeling my hair flopping around at the roots because it was so soft.

Best of all, my hair is NOT greasy or oily and it isn't heavy. My hair, after using this, is purely soft and smooth. I liken it to silk.

I only use this once a week because unfortunately this is very expensive. $70 AUD for a 200ml jar is extremely pricey, but I'm willing to pay that much due to how it leaves my hair feeling.

If you're thinking about buying this, do it. I promise you, your hair will be thanking you after you do it.

One of worse masques I tried.

Pros: Makes hair very soft

Cons: Makes the hair very electrisized looking. Not sure how to explain, but hair looks quite bad in sense that there is lots of hair going in weird shapes and directions. I must use another masque on top of this one or it looks terrible.

I use this masque for 3 weeks already along with Bain Architecte masque (thee green one for damaged hair) and Elixir Ultime masque (the gold one for ultimate shine), I use Masquintense as my daily conditioner and leave it for 5-10mins. And use it once a week for 15-20 mins. Just apply a little amount and rinse it with cold water.

Anyway, my hair was thick, long, fine, sensitized, little split ends, frizzy, and dull.

I think this is one of my HG hair treatment. In just 1 application, it leaves my hair soft, silky smooth, untangled, light-weighted, straight, and I kinda love the soft baby powdery scent! And my hair is getting softer now.

I use this whenever I feel my hair's drying. However, if my hair got damaged cause iron flatting, I definitely goes to Bain Architecte for healthy hair.

I definitely recommend this masque to everyone with normal-dry hair and want their hair silky smooth and light-weighted! Will buy again after runs out.

This hair masque is awesome! This and the Kerastase Oleo-Relax masque are my favorite hair masques. I love the scent of this. I shampoo my hair, towel dry it, leave this product on for 20-30 minutes, and then rinse it out. It makes my hair super soft and really helps with damage. The Oleo-Relax masque helps better with frizz, but this one doesn't weigh my hair down quite as much. I use the Masquintense for thick hair even though I have fine hair, and it works great. I highly recommend this masque.

"First of all any idiot claiming this has protein in it, no, it really doesn't. NONE of the kerastase products use protein, that's redken. Moving on"

From Kerastase's OWN website:

"Proteins: Restore nutrition on the lengths, leaving the hair nourished and steeped in softness"

Those who are incapable of research, should never call those who are, idiots. But, I guess that just goes to show teenagers really don't know everything like they assume. Moving on.

This product works extremely well for me, but I just couldn't get past the fragrance. It's horrible compared to their other products. The Oleo-Relax smells absolutely devine and is a better product all around, but to each their own. As the Bain Satin and Lait Vital carry the same scent, I ended up giving them to my 16-year-old. She wasn't bothered by the fragrance, appreciated the way they worked, and isn't busy on the internet calling people idiots. I couldn't be happier.

First of all any idiot claiming this has protein in it, no, it really doesn't. NONE of the kerastase products use protein, that's redken. Moving on...........I ADORE this hair masque, not only is it a HG of mine, my mother has used this ever since i can remember (early 90's, im 19) and it hasn't changed much, no other masque conditions, detangles, smooths and overall just make's the hair feel like raw silk as much as masquintense does. I have platinum blonde hair that used to be rather fragile, and i definitely credit this for restoring my hair, you would literally think it was virgin hair it blow dry's so beautifully. if your hair is dry/brittle/damaged please use this masque, infact i beg you to use it, after just 1 wash you won't be disappointed.

IT STINKS! smells like INTENSE baby powder or old grandma smell. and just reaks really bad it is so strong. if it had a nice smell like the other types from kerastase i would buy again, in results, it made my hair feel pretty moisturized, i have split end hair all the way up my hair shaft, but the smell is just rank. i'm waiting on the green tub to arrive so i use the pink tub which doesnt restore, just makes it easy to comb. if the green one isnt good, i think i'l stick to morrocan oil, you cant go wrong. just if u use the orange lid mask, that is high in protien so dont overuse.

I was very excited to try this masque. At first it seemed to make my hair feel better but then I noticed some shedding. I did not want to associate it with this product but it only got worse when I started to use on of Kerastase's shampoos which I will do a separate review of. The shampoo had salicylic acid listed as an ingredient and I know that it is usually used on the skin for acne and exfoliating. I did not notice this until later at home. The two products together did not work miracles for my hair and there are surely products that are closer to a miracle than this one was for me. After rinsing the masque out, I needed lots of leave in spray to keep it from feeling so dry. It was not what I expected out of such a pricy masque, so highly reviewed everywhere. I will not repurchase or allow salons to use this in my hair. I do not think it is healthy. One woman in a beauty supply store said, "It's the French way. It looks good at first but is not good for you at all."
I would not recommend this product. I am so surprised because I like the drugstore L'Oreal Evercreme line, haha.

After trying the oleo relax hair mask and the chroma riche mask with great results, the next mask I wanted to try on my dry, frizzy color treated hair was this one.
I left it on for about 5-10 minutes in the shower and found it to be an intensely moisturizing treatment. I didn't love the scent, it's a little bit 'old lady' . It really gives dry hair a nice 'slip' feeling. If you don't wash your hair daily (like me), you may find your hair looking a tad greasy the next day. So, I would really only recommend it as a weekly treatment. All in all, a great deep conditioner, that will help moisturize dry, damaged hair. Very expensive, but worth buying if your hair needs it. For my hair type, I have found the Chroma riche mask to be my favorite.

This is my ultimate hair treatment. I use the one for thick hair,the one for fine hair for me is just like a regular conditioner.
I have extremely long,thick, dry,frizzy dyed,,knotty hair. If I use supermarket ( non salon) shampoos and conditioners my hair is matt and knotty and takes ages to comb through. This treatment is unreal, my comb just glides through my wet hair now. I wash my hair with Bain Satin 2 , towel dry, apply a very small amount of Kereastase, massage through, cover hair in a shower cap or plasticbag, then cover that with a towel and leave for at leasthalf an hour. I always leave for an hour.
I just let my hair dry naturally as it dries so smooth and shiny and smells divine.
Sheer indulgence!
