I found this did nothing for my hair, I have relaxed hair that is very dry and thirsty, I do like the smell and will continue using it until it runs out but will not re-buy it.

I am currently out of this product and I sure can tell a difference! I use it as a leave-in conditioner, and for the past few days after running out I am losing almost twice the amount of hair in the shower, my hair is snapping more, and although it is not marketed for frizz control my hair is frizzing much more without this product! Needless to say, after payday I will be running, not walking to Ulta to repurchase this beloved friend. I also use the Redken Extreme shampoo and conditioner, and this line has accomplished more than any other high end products, organic DIY masks, or even chemical treatments have with my hair. My hair is very frizzy, dry, and breakage prone due to some hormonal imbalances, and this line improves my hair like none other, and more importantly my confidence. Thank you Redken.

This is amazing stuff, it is extremely lightweight does not weigh hair down at all, it does the job of mending split ends its fantastic

I love this product and use it as a weekly treatment. i know its a leave in and it works great as a leave in. however i use it by applying it all over my hair, especially at the roots/scalp, and then sleeping on it overnight. rinse out as normal the next day. i have been doing this for a year now and my hair is strong and healthy and i have noticed it grows faster than before i used to do this. it is an excellent product.

This is by far the best leave-in conditioner I've found. No matter how much I use, my hair never feels crunchy or looks oily. The product works well with both blow drying and air drying. It mixes well with other products such as volumizers, so I can use it when I'm styling my hair as well. It leaves my hair soooooo soft and even adds a bit of volume with regular use. This product has greatly improved the overall health of my hair. It completely seals the cuticle and prevents split ends and flyaways. It smells great too. The only thing I don't like is the bottle; I'm not a fan of pumps, as I find it difficult to control the amount of product you get, and the pump can be wasteful and cumbersome. The travel size versions are just standard twist off tops, and I wish Redken would use this bottle type with the larger size. I recommend this product to all my girlfriends.

I used this years ago but got bored with it eventually. I've got fine hair that - even though it's no longer bleached and I take very good care of it - is VERY prone to snapping. I've tried every product on earth and I think that my hair just naturally lacks protein because of its fine texture. It's always soft but definitely needs strength. So back to Anti Snap, new IPN formula, which I've been using for 2 weeks now. I use two pumps every time I wash and it's perfect - never leaves my ends crunchy or hard, doesn't seem to build up protein or leave any residue. I LOVE the smell too! My ends definitely are in very good shape and I feel Anti Snap is already helping. Hair is very soft, shiny and generally healthy looking. I use the Extreme shampoo, conditioner and CAT too once a week.
Note that my hair is untreated and virgin, I do blow dry but never straighten, and yet the Extreme products doesn't make it hard. I was pretty aware of possible protein overload, but this hasn't happened at all. Very reasonable price if you buy online (here in Denmark Redken is just as expensive as Kerastase).

This is the product everyone needs when trying to prevent split ends. I've been growing my hair out for 4 years now and I was getting horrible split ends. Of course I went and got a trim every 4-6 weeks, but they kept coming back really bad right after I got them cut! I use my GHD about once a week ( if that), never blow dry, use AG's Recoil curl cream, etc. I've had this for about 10 months now but I was always too scared of using it on a more regular basis because I don't want a protein overload, but on my most recent cut the stylist told me to use a pump every time I wash my hair to prevent split ends as it is a lighter protein treatment. It has been helping SO much to prevent split ends! My ends are still softer and stronger than they normally would be now. I use this only on my ends. Also, the smell is really digusting- like potatoes! BUT it is an amazing product and it is so good it doesn't *need* to smell good. I highly recommend this and will continue to purchase this for years to come!

Great product for strengthening hair. Be careful to not use too much. Also when using this try to eliminate other proteins in other hair products or it will be too much of a good thing. Will always continue to go to this product when I need to. Try some around your roots to help hair from the start.

So I finished two bottles of this stuff and I think it is time to be reviewed. About my hair: it is thick wavey and it has been bleached three times and dyed over that. You can only imagine the damage my hair has. This stuff has saved my hair. After I used up my first bottle, I didn't rebuy and I noticed my hair having more breakage and becoming more stretchy when wet. Then, I bought another bottle and started using it again and I have so much less breakage. It is one of those things that you really notice when you stop using it. I think this product is a must for bleached hair. I do not use it after every time I shower. I use it about 2 times a week and about 3-4 pumps per use for my thick hair that is halfway down my back. Also, only put this in on damp hair! It is amazing. My HG product for damaged hair. So, if you have bleached damaged hair, please give this a try! I can't live without it.

If i was stranded on an island and could only bring one thing this would be it :p since its only used on your ends its greatbang for your buck.
