Rated 5 out of 5 by from Amazing product! It's hard to see any physical benefits from this product bc all the good stuff is working internally but it has a pleasant smell and makes your scalp feel great!

Rated 5 out of 5 by from Smells amazing! I received a sample of this product in exchange for my honest review. This cream has been life changing, I typically prefer a spray leave in treatment. I sectioned my damp hair and went through each section applying the cream on it, a little bit goes a long way. I think it was about a pea size amount through each section. I let it sit and then blow dried. Instantly my hair was soft and shiny

Rated 4 out of 5 by from Excited about this, seals cuticle ! I've been using this entire line and it's been really good. It hasn't been long enough to see if it makes my hair grow longer, but from looking at the ingredients I can tell that it will strengthen my hair, and therefore allow it to grow longer.

Rated 5 out of 5 by from So bouncy My hair feels so bouncy and my ends are sealed and smooth after blowdrying this in to my hair. I love this and will continue to buy it!

Rated 5 out of 5 by from Redken does it again I used this along with the Shampoo and Conditioner and I'm very impressed ! The system as a whole is a great product and I will continue using

Rated 1 out of 5 by from Not necessary I honestly couldn't even tell if this was really doing anything for me or not and kind of weighed my hair down a little. Would probably skip out on this next time.

Rated 4 out of 5 by from Smoothing and sealing! I like this split end sealer treatment but it is not my favorite for frequent use. I think this product works best when combined with something else that is hydrating as a leave in, but on its own i think it can be a bit heavy and drying. I like the added benefits of castor oil, biotin and niacinamide! This gives nice shine and smoothing for the ends of the hair and helps with frizz. I think when combined with another product this will treat the hair longterm and help to reduce breakage and promote growth and length. Using this system as a whole has forsure improved the shine and managability of my hair and with limited usage of the treatment!

Rated 3 out of 5 by from Great smell / use sparingly This product should be a salon only product as the consumer may overuse which can cause dryness and brittleness to the hair . When used properly this adds nice softness and shine to the hair !

Rated 5 out of 5 by from New favorite!!! Okay, we KNOW there are TONS of treatments out there, but overall, I really liked this product. It wasn't too heavy, my hair felt protected and it didn't make my hair greasy after a day. My main concern is protecting my hair so it can grow long and healthy and I think this product will do that.

Rated 5 out of 5 by from Works great This product is for anyone who needs a little mend with dry/damage hair. It's similar to the acidic bonding leaves in treatment and works on all hair types/textures without leaving the hair feeling heavy or greasy looking

Rated 5 out of 5 by from Great treatment This treatment was followed after the conditioner. It makes your hair soft and shiny and will allow you to blow dry it will good volume.

Rated 5 out of 5 by from Love the whole system! I really like it ! i use this after the shower on very towel dried hair and start at ends and work up to roots, definitely not heavy and super moisturizing, love that it has that sealing property for my cuticle!

Rated 5 out of 5 by from Amazing, Fantastic Clients and Pros will Love I love this for my clients. Especially clients that want to grow out their hair. It softens those damaged ends your clients don't want to cut off. And not only that it makes the hair look less frizzy, super moisturized and feels super soft.

Rated 5 out of 5 by from Nice Leave In Doesn't weight hair down, moisturizes and smells great

Rated 1 out of 5 by from Leave In There are way better products to use than this line. Hair gets week and brittle fast with the Extreme Lengths line. My new client's hair was previously damaged. I used this line on them and their hair became more compromised then what we started with.

Rated 5 out of 5 by from Give It A Try Such beautiful packaging! I have used this shampoo, conditioner and sealer on my hair a few times now. I haven't used it enough yet to see if I'm actually getting less breakage, but I really like it so far! I rub the sealer throughout my hair . It doesn't weigh it down. It is actually undetectable which is very nice!

Rated 5 out of 5 by from Hair felt noticeably stronger and more resilient The REDKEN Extreme Length Sealer Leave-In Treatment is a fantastic product for those who are looking to grow out their hair or simply strengthen their strands. This leave-in treatment is enriched with biotin and castor oil, which work together to fortify the hair shaft and prevent breakage. After using this product, I noticed a significant difference in the overall health and appearance of my hair. My hair felt noticeably stronger and more resilient, which made styling and brushing much easier. I also saw a reduction in split ends and breakage, which has helped me maintain longer hair without sacrificing its health. Another thing I appreciate about this leave-in treatment is how lightweight and non-greasy it is. Even though it's enriched with nourishing ingredients, it doesn't weigh my hair down or leave it feeling oily. Instead, it absorbs quickly and leaves my hair feeling soft and smooth. Overall, I highly recommend the REDKEN Extreme Length Sealer Leave-In Treatment to anyone who wants to promote healthy hair growth and prevent breakage. It's a high-quality product that keeps on its promises and has quickly become a primary in my hair care routine.

Rated 5 out of 5 by from Lightweight Great for after freshly washed hair. I can tell my "split ends" are healing. Ali though I do bleach for a decisional look, it can wreak havoc on my hair. This product has definitely reversed that.
Date published: 2023-05-18
Rated 5 out of 5 by from Great stuff I used this on my ends after using the shampoo and conditioner with the same name. I usually don't like leave in conditioners, unless they are in spray form. But this one made my ends look really healthy and soft. I am hoping that over time it helps with my split ends.
Date published: 2023-05-18
Rated 5 out of 5 by from Good Product I used this in combination with the extreme length shampoo and conditioner. The result was smooth, manageable hair with less frizz and more shine. The hair wasn't weighed down or oily feeling the next day. These products are great for long hair. I loved the smell too.
Date published: 2023-05-18
Rated 5 out of 5 by from Would buy this again This product is amazing. It helps make my hair more manageable and smooth. My ends are feeling and looking better!

Rated 5 out of 5 by from Leave in Great leave in love using it with the shampoo and conditioner, smells great and leaves my hair soft with volume. Don't know about growth yet have only used it for a week.
Date published: 2023-05-17
Rated 5 out of 5 by from I really like this I have some pretty tangly hair from split ends that I just can't bring myself to part with. This helps get the comb/brush through. A little goes a long way and really focus on the midshaft to ends. It can be heavy so use sparingly.
