This is my favourite new shampoo! I have fine hair (not baby-fine) that needs moisture, because I flat iron it every two days after I wash my hair. Most "moisture" shampoos leave my hair really oily and greasy a few hours after use, but this shampoo leaves it soft and super clean for a whole two days! I have been using it for the past two months and I am so impressed. It can be really hard to find a shampoo that is moisturizing but not too moisturizing that you get the oily residue if you have finer hair.

The shampoo makes your hair feel smooth and silky, then again I don't know whether it is because of all the coatings attached to the hair. I have fairly sensitive skin and one thing I notice is if I accidentally let the hair touch my skin all night the next day I got red itchy lump on that area. I think it must be all these "goodies" they put in the shampoo that give me the reaction.
It took me a while to realise this. I am now switching to another brand.

Horrible! This is just a ridiculously overpriced silicone shampoo. After using this and Lait Vital I literally lost a clump of hair trying to just comb my hair out...it was a tangled dried out mess!! I have baby baby fine hair and I try to be as gentle as I can, but ...ugh. Totally disappointed esp since the masquintense is awesome...oh well, guess I'll stick with the bain de force + ciment which are 10x better. UGH... 2 days later and my hair is still shedding from this - what the heck is in this stuff!

terrible, my hair is normal, not coloured and this shampoo made my hair looking dirty on the roots right away, it feels like I went to gym and worked out for 3 hours and after I spend 3 nights fishing without having shower! No jokes, even if I wash 2 times my hair, nothing helps, it is the worst shampoo I ever tried!

Ever since using this shampoo, I wake up every morning with silky hair! In fact, I can go days without having to comb my hair- that's how incredible this product is, especially for lazy people like me! Even with constant use of the hairdryer, my hair feels moist and fluffy instead of damaged. The shampoo is dispensed out of a little hole at the top of the bottle, but it's still easy to control how much you use. At first I used to think that the smell was too full of chemicals, but as I continued to enjoy the benefits of this shampoo, I grew to like the smell!

Best Shampoo ever. Hair very soft and bouncy, also improved smoothness.

I really like this shampoo, it made my hair very clean, shiny and soft. I wouldn't use it every day, because it can make your hair a bit greasy, and can cause dandruff. I still haven't found my HG shampoo, but I'll keep on searching until I do!

Used to think this was my HG product ... used it now for about a year or so, and have had great results. Then one day I ran out and had to pick up some Dove Oil Nutrition or whatever that stuff is called ... and guess what! It does an as good as, if not a better job than Kerastase ... if you're reading this and wondering whether to go spend £12 on this shampoo, stop! Try Dove first.

This is one of the best shampoos I have ever used, however it smells like old lady though. :( I am forcing myself to keep using because it is just that good.

This is the only Kerastase shampoo that my hair and scalp completely agreed. My hair type: Asian, thin, naturally straight hair, black, been colored and Japanese perm every now and then. I've tried Bain Divalent (good, used it in early 2000, formula might changed now), Bain Reflection (purple pink bottle, didn't like it at all), Bain Resistance (makes my scalp oily, yikes), Bain Volume (I don't remember well, I guess it's so so). Bain Satin 1 is so perfect, not too over conditioned nor too silky. I don't like too much conditioning properties on my hair, because my hair is thin, flat and fragile with no texture, therefore this is enough. My hair stays manageable and healthy when using this shampoo, no matter in humid, cold or dry, warm, hot weather. It's the only one that works. I like to pair it with my fav Japanese conditioner, called NIGELLE LX (when I abused my hair too much) or NIGELLE AX. If you have the same hair type like me, thin, fine, flat, you only need a light conditioner with this shampoo. The shampoo already does everything. It doesn't make my scalp oily on 2nd day, unlike other shampoos. Note: I live in Los Angeles, low humidity and hard water. This is a must, but I don't use it everyday to prevent build up, plus, it's expensive.
