Kerastase Genesis Defense Thermique Blow Dry Primer For Straight, Curly and Coily Hair 150ml/5.1oz

I bought this recently, after highlighting made my hair weak and dry. It made my hair very soft, which was great, but almost too soft to hold a style. Be careful to only use a small amount. I spray a very small amount, only 2 sprays, into my hand then smooth through my hair I leave for a about 5mins. Clean teeth , get makeup out, make a cuppa, then return to style my hair. After 5 mins it has done it's work. If you hair is very fine, and lacking in body, and tends to go flat, (like mine!) this product also puts a bit of body in too. I must admit I need to use a good quality hair spray to keep the style in place. I would recommend, but you need to "trial" how much to use over the first few times you use it. I don't use it every wash. Perhaps once or twice a week.

[This review was collected as part of a promotion.] Fab product! Very silky result on my hair without being sticky or heavy. Smells lovely and a little goes a long way. Would highly recommend.

[This review was collected as part of a promotion.] Hair feels softer, doesn't weight it down when you put it in Easier to get my hairbrush through my hair

[This review was collected as part of a promotion.] I was not optimistic when I first used this, as I have used so many miricale claiming products that always fail. I followed the instructions and instead of spraying directly on to hair I put some on my hands and put through, I wasn't sure I had put enough as I couldn't feel it on my hair, I continued as normal styling and drying my hair and can honestly say that my hair really felt and looked much more healthy and felt so soft and shiney. I will definitely buy more and recommend

I absolutely love the smell of all the genesis products , I would 10000% buy the perfume if it came out ! great product

I have only used this twice, it really suits my fine hair, i have so many people saying your hair looks nice, only since i`ve been using thermique, love love love it.

[This review was collected as part of a promotion.] Having received the sample I was tbh a bit sceptical having triedany products before and suffering with menapause symptoms affecting my very fine breakable hair .i have to say after a few weeks of using I did notice a difference .it didn't dry my hair out like some products do and it made my hair more manageable for detangling too .it is making a slight difference which is better than none to the process of combing and slightly less breakage but will continue to use .

I've been using the genesis range for a year, after experiencing significant seasonal hair fall last autumn. It worked wonders at the time but now my hair is feeling really dry and frizzy, and cannot hold a style. I washed and dried without using this spray recently as I was having my hair put up for a wedding, and it did blow dry much easier, so I'm not sure if it's the spray that's contributing towards the dryness. It was out of stock for a while so I'm wondering if the formula has changed? Going to switch to a moisturising range for a while and hope that makes a difference! A shame, as I've recommended the range to lots of friends, but my hair is just so parched right now it needs a change!

I bought this suite of products at the urging of my stylist about a month ago, to replace my beloved Kérastase Stimuliste. I prefer Stimuliste in every way, but as far as the final result goes, Genesis is fine. This thermo-protection doesn't really seem to do a lot. I still end up using a finishing oil to give my hair a bit of a gloss and tame flyaways. My hair looks and feels good, I just wish it didn't leave me smelling like a 15-year-old girl. I think my search continues - I just can't have this stench following me around.

My hair needed something to protect from the heat of straighteners. After much research I ordered this product on line. Felt quite excited. However after after first use today my hair is dry, with hair sticking up on top and dull looking. Disappointed is not a strong enough word.
