This is the best treatment I have tried, and I´ve tried a lot. A good alternative to cutting your hair of.

Best I've found so far
This is great my hair is over processed and dry from using my straightening irons. This instantly nourishes my hair and keeps it looking good. Excellent buy.

Too good to be true!
After a distatrous visit to a new 'cheap' hairdresser to have my hair coloured (ten years of colouring, once a month) I decided that my long locks deserved better and went somewhere that knew what they were talking about. They said that I had at two choices - have at least 4 inches cut off the length (nooooooo!)or use this product and come back to have the colour fixed once the course was finished. I obviously chose this option, and will never be sceptical about any Resistance products again - it's amazing stuff and well worth the money. I noticed a difference after the first tube and I was able to have my poor hair highlighted and lowlighted with minimal breakage. Highly recommended.

give your hair an intensive conditioning treatment
Good product to give your hair an intensive conditioning treatment. A word of warning don't leave on longer than recommended as it can irritate your scalp as it is so powerful. I also think it is quite pricy as an alternative I would buy the resistance age recharge as it lasts longer.

ABSOLUTELY SUPERB
My hair is higlighted and very fine and brittle. I used to use Tigi and so many cheap products that dont do anything for my hair, only making look dull and weak. This is just the best I have ever tried, I noticed the difference straightaway. The hair feel stronger, very shiny and smells lovely. The best when you use straighteners. It is quite expensive but when I see all the half empty bottles of treatment i have used in the past in my bathroom then I wish I didnt waste my money in those and treat myself to this product. Its worth it!

I tried many different hair products to treat my damaged hair. Nothing ever worked, but this is the best treatment ever, after 2-3 washes my hair was normal again..

AMAZING!
I have been using these treatments for roughly 3yrs after my hairdresser suggested them for my overprocessed hair. I constantly dye and straighten my hair which leaves it looking and feeling terrible... but not anymore!! Since using these treatments and also the shampoo and conditioner my hair has never been in such good condition. I have used other products on the market such as Alterna, Redken and other high street brands and nothing comes close. You will not be disappointed!

If you want stronger hair, try this!
Ive had limp fine hair that has split ends, no longer though as I have been using a lot of products from the Kerastese range and my hair is so much better. Its actually amazing at how much difference products can make. Invest in you hair girls! (See my other reviews as I have tried many other products too)

I finally have MY hair back- SILKY,SMOOTH,SHINEY!!!!!!!!!!
I have always taken very good care of my long fine hair and it showed.BUT Since going blonde and having had a bad job redone( 3 lots bleach in two weeks) I was pleased with the colour but not the texture-dry and cotton-wool like oh and dull once I started washing it myself. Somethings worked to make it hair-like again(beyond the zone last call was good and redken all soft heavy cream was even better!)but ONLY this has given me shiney, smooth and silky healthy-looking hair again!!!!!!! FANTASTIC and could tell the difference as soon as I applied it.WORTH EVERY PENNY!!!

Brilliant!!
Loved this product. Left hair feeling soft and shiny. Hair felt really conditioned. Good to use as a weekly intense treatment.
Madelene
It's great
This product smells really nice and it does exactly what it says. After using this product my hair looked shiny and healthy and it felt great. I didn't have to use any afterproducts like a shine serum.

Love this!
I used this after have some major highlighting with bleach which left my hair rather straw-like. Loved this product, left my hair in tip-top condition and back to a silky soft state. I also used the Ciment Thermique afterward to style and my hair is now in lovely condition.

My hair has never been stronger!
I really love this product for strengthening and adding new life to my fine over processed hair. I have read some reviews that complain about it not being conditioning enough... but really the primary function of this conditioner is to strengthen, not soften hair, I rotate it with the aqua-oleum and find that together they really keep my hair looking fantastic!
Stephanie
It really works!
I have bleached hair which was in great condition until a home bleaching session went wrong. My hair became ridiculously dry and looked like a brillo pad. I tried loads of products on it and nothing helped. Eventually most of the top section broke off. A hairdresser recommended Forcintense and I was really sceptical, as my hair was in such a state and Forcintense is quite expensive. I used all 3 applications in a week (you're meant to use each treatment once a week). My hair now looks like hair again! It's a miracle!!! My hair has stopped snapping off and now I can style it without worrying that I'll need a wig!If you're hair is over-processed and you can afford to splash out, definitely give this a go!

The best product ever
I`ve been using this product after coulor treatment several times and it works very good. I`ve tried redken, tigi and other but I always come back to this product. My hair is frizzy and very dry and after each time coulored by the hairdresser I`ve got to treat i with a wonder cure this is.

Brings hair back to life
I was recommended this product along with the others in the range by my hairdresser. I'm always a bit sceptical of hairdresser recommendations however I thought I would give it a go as my hair was in poor condition due to having chemical straightening. It worked wonders, made my hair shine and look really full bodied. I now do one of these every 6 months using the bain de force and ciment anti-usure regularly to keep my hair strong and healthy and it really helps as regular Yuko can leave hair dry. Worth every penny!

Best hair product EVER!
At long last my quest for the ultimate hair product has ended, Forcintense is superb!! I wish it came in huge big bottles!
tanjabrown
A+++++ product, highly recommended!
This is absolutely brilliant, like all other Kerastase products (I always ruefully come back to Kerastase after having strayed to cheaper brands...). If you have highlighted and weakened hair like mine that gets subjected to straightening twice a week, then nothing can beat this! Even after only one application followed by Ciment Anti-Usure I could see a noticeable difference in shine and texture of my hair - well worth the money!

EXCELLENT PRODUCT THAT DOES WHAT IT SAYS!
I totally recommend this trreatment for strengthening hair it really works!! My hair is bleached on top, and had become very weak, it even started to snap off when I visited my hairdressers! After using this product in conjunction with Bain de force and Ciment Anti-usure, the next time i went, my hairdresser couldn't believe how much it had improved! Not one piece snapped off! If ur gonna buy a strengthening treatment then this is the one to buy!!!!!!!!!!!!!!!
