Rated 3 out of 5 by Hross 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 Flynsolo2 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 Alisha 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 Liz 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 1 out of 5 by Bn 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 Christy 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 Nikaa 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 Teresa 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.

Rated 5 out of 5 by SP 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.

Rated 5 out of 5 by Shoebug 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.

Rated 5 out of 5 by Linds 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.
