Rated 1 out of 5 by from Makes your hair ends look DEAD and STRINGY THE WORST LEAVE IN EVER. I bought the whole system--Shampoo, Conditioner and Leave In. Total Disappointment. Makes the ends of my hair hang flat and look DEAD and STRINGY. I thought REDKEN was alot better than this.

Rated 5 out of 5 by from Amazing Leave-In! Such a great leave in for anyone growing out their hair, or wanting to care for their long hair! Lightweight formula adds strength and protection for mids to ends without weighing the hair down or looking greasy.

Rated 5 out of 5 by from Smooths & Conditions This did a great job of making my hair feel smooth and conditioned, with no frizz or flyaways. It can be a little heavy so use very sparingly if you have thin hair.

Rated 5 out of 5 by from Love this leave-in! This leave-in conditioner made my hair look so much better! I have color-treated, flyaway, sort of frizzy hair, and most leave-in conditioners are just heavy and feel like too much product. This one is different! After less than a week of use, I found my hair to be much more manageable and smooth. LOVE. IT.

Rated 4 out of 5 by from Good addition to daily hair care I enjoy that this treatment adds much needed shine to my hair. I have noticed considerably less split ends and breakage with the treatment plan after two months.

Rated 5 out of 5 by from Amazing product This product is amazing and made my hair super soft and seemed to make my split ends less. My hair was super shiney and healthy looking after usage. I really enjoy using it.

Rated 5 out of 5 by from Nice product This hair treatment is very nice. It smells great and works on the hair! A little goes a long way. This leave-in product applies to the hair easily leaving it smooth, detangled, soft and shiny. Like with a lot of products, it takes time to see long term benefits, but it instantly gives the look of visibly healthier hair. The hair looks smoother and no split ends are visible

Rated 4 out of 5 by from Works well I really like Redken products. This leave in treatment helps my split ends and also look healthy. It really helps in the summer sun and pool! I would recommend for long hair.

Rated 5 out of 5 by from Awesome! I have been using this product for a few weeks and have noticed that my hair is much softer, smoother and has a great shine to it. It smells great and a little goes a long way. I have noticed my split ends are not nearly as bad as before using this.

Rated 5 out of 5 by from helas damaged hair My hair got damaged and was breaking off easily because of how I handled it over time. I have been using this treatment for almost a month now and my hair is getting stronger and healthier. I don't experience breakage like I use to prior to using the treatment. I use it 3-4 times a week on damp hair and style my hair as usual. My hair is smother and has been growing back gradually but steadily.

Rated 5 out of 5 by from Great leave In treatment My hair definitely feels a lot smoother after using this leave in. I definitely recommend

Rated 3 out of 5 by from Too soon to tell This product doesn't seem like it's incredibly helpful, just added weight in my very fine hair. I prefer a spray anyways that's a little more watery so this wasn't a great match for my lengths.

Rated 5 out of 5 by from Great for growing out hair I received this item to review in exchange for my honest opinion. I have used it for two months now after every shower. (2-3 times a week). My hair is bleached and color treated. What I like: The texture- other products legs hands sticky at times. Doesn't feel heavy. Doesn't look or feel weird once hair is dry. Easy to use in the squeeze tube. Feels great as a leave in conditioner. What I don't like as much: Because you only use it on your mids to ends, you still have to use a detangler. Is it a miracle product? Not in terms of growth. But as color and bleach damaged as my hair is.m, I could tell that my ends have really appreciated the treatment. I will continue using it as I grow out my hair and would recommend!

Rated 5 out of 5 by from Nice weight to it I got the Redken Extreme Length Leave In Treatment for SC for free to review. I really like how it adds a good weight to my hair so that it air dries straighter than it would without any product in it. That means less heat I need to use when styling. It doesn't feel heavy or greasy so all in all a great option for leave in conditioner!

Rated 5 out of 5 by from I love it!!!!! The Redken Extreme Length Sealer similar to my long hair, made my hair super smooth and I got a lot of inquiries of what I was putting on my hair. I cannot speak on hair growth because I got a hair cut, but my hair looks super shiny and silky. To the touch it's super soft. I cant stop touching my hair. I really love how it feels and looks and how many compliments I get. I have super thin hair and very little and my hair looks full even though it is not and the smell is soooo good! My hair felt light too, and it wasn't greasy. I will definitely buy this in the future.

Rated 4 out of 5 by from Smells great and helps with split ends! My hair grows very quickly, but it is prone to breakage and split ends, so I've needed frequent trims. This Redken leave-in treatment has helped me reduce the number of trims this year and also has kept my hair stronger. I've had very few visible split ends! The conditioner also smells amazing. I can't give it five stars because the treatment does leave my hair looking oily/greasy sometimes, but my hair is prone to that also. I think others might not have that issue, so I'd definitely recommend this product!

Rated 5 out of 5 by from Favorite new leave in! My hair looks and feels so much healthier now after using this line. I'm trying to grow my bleached hair longer and this has been an awesome conditioner. Smells nice, too.

Rated 5 out of 5 by from I love it! I tried this product and I must say that I loved it, the texture it leaves on my skin is very soft and not greasy. In the time I have been using it I have noticed the change, I think a better product that is impossible! I would get it again and from today it is among my favorite skin products.

Rated 5 out of 5 by from Smells wonderful, leaves hair soft and silky I have really long frizzy hair and am always on the lookout for good hair products. This Redken leave in treatment smells wonderful and is a great treatment for smoothing out frizz and keeping hair tame, while also providing much-needed moisture. With a few weeks use, my hair looks and feels more luxurious overall. A little dollop also goes a long way. I use two dime-sized dollops per day, and it provides coverage for all my hair (which runs down my lower back).

Rated 5 out of 5 by from Amazing product This product helps my fine and split-end prone hair remain split-end free! I heat style about 2x a week and trim 1/2 inch of my hair about every 4 months and this has helped my hair reach waist length without as many split ends as I used to have

Rated 5 out of 5 by from Excelent on my fine hair I have long but fine hair. It goes past my shoulders halfway down my back. I liked how Redken's Extreme length leave in treatment feels when I put it on and I do feel it helped my split-ends quitea bit. My hair grew 1 inch in the last two months during the time I used it. I notice that I have less split-ends now than how many I used to have. There is no detectable scent to it, whicch is another bonus for me.

Rated 3 out of 5 by from Disappointed I really wanted to like this leave in as I usually do like Redken product. However this wasn't the case for this leave in. I felt that it made my hair feel hard and dry. I may give it another try in hopes that I get a different result this time but as of now I am not liking this leave in. I wouldn't recommend this leave in based on my experience but I would definitely tell others to try it for themselves.

Rated 5 out of 5 by from Best silky leave in conditioner I have seen amazing hair improvement in texture color and gloss. It is perfect for smoothing and styling. Not too sticky or tacky
