How to Use
Rated 4.62 out of 5 stars
First and foremost, I love the scent of the shampoo! It's a cotton candy-ish smell, but not overwhelmingly powerful. It lingers forever, I've never gotten so many compliments on how great my hair smells!!
I have waist length, thick THICK, wavy/curly hair. It's pretty coarse, hard to comb through, and I tend to have drier ends, which split often, even with regular trims. I had just gotten a trim before starting the Extreme Length regiment. I typically only wash my hair about every 3-5 days, just depending on how it feels. I kept my same hair care routine while sampling the line.
This whole line is fantastic, and this leave-in it's the icing on the cake!! I have very coarse wavy/curly hair, and even with regular trims, my ends dry and split. I've tried a lot of different products, but usually if something keeps my ends moisturized, then the rest of my hair is weighed down, and looks heavy or dirty. I've been using this leave-in conditioner, after using the Extreme Length shampoo and conditioner, for almost a month, and I'm so impressed with how it performs in my hair!! It's truly made my hair feel soft and luscious! I've never been able to say that about my hair unless I'm walking out of a salon with a fresh blow-out. My ends aren't nearly as dry, which is stopping them from splitting. I'll be able to go longer between trims!
The product itself isn't the least bit sticky, and absorbs quick and easy.
I take biotin vitamins, and the line also contains biotin, which it great for hair and nails. I've been using the shampoo, conditioner, and leave-in for almost a month now, and my normally hard to manage coarse hair feels soft, and my ends aren't splitting nearly as much as before. I don't know if it's related, but it must be, because my nails are also much healthier, and growing like crazy!
The formula is fantastic!
I ordered this because of the great reviews. Sadly I am not in love with it! It smells absolutely amazing. Unfortunately it makes my hair sticky and hard to brush through. (You know how some leave in treatments just make your hair feel sticky, this is one of them). For reference I have very long fine hair so it's prone to breakage. It works ok if I apply AFTER brushing but if applied beforehand it makes everything sticky and pulls too much hair out when brushing. I think this makes me hair soft but not as silky smooth as some higher end brands I've tried like Kerastase. I love the smell though, wish this worked out better for me!

I love love love this product. It saved my hair when it started thinninf from autoimmune complications. It's so worth it and the tube lasts such a long time. The smell and texture are great. I wish this was a pump but I'm still extremely happy with the results.

Routine: Redken Extreme (with protein) or Redken Extreme Length (with Biotin) Shampoo, Extreme Length Conditioner & Extreme Length Leave In Sealer. A couple weeks of use and my hair looks/feels better than ever. My uneven wavy, frizzy hair is silky soft with a majority of the frizz gone, and my need to layer multiple products in my hair has been eliminated. Only time will tell on the advertised lengthening factor, but initial results are very promising as I've noticed much less breakage/fall out. Finally found the hair product combo I've been looking for, which I didn't think existed until now.

This product is amazing! I use it as a leave in and a little bit goes a long way. My bleached and damaged hair loves it!
Sam from Bristol, Pa
I used this treatment on my ends after each shower I would wash my hair. And I love it. It left my hair feeling great and not heavy at all. I would let me hair air dry and loved the look achieved without trying. So the moral is my hair looks amazing and feels great

I've been using Redkens Extreme Length Leave-In Treatment for a number of months and have developed stronger and more fortified hair. I generally have pretty dry and breakage prone hair due to chronic colouring and bad hair care decisions. In the last few months my hair has reverted to how it was before I ever began using hair color or products. It feels soft and silky and my split ends have gone by the wayside. It's a relatively inexpensive product because you don't need a lot to work through your hair length and ends and the bottle is decent sized. I'd make sure you don't use it near the crown of your head though, as it can give your scalp a greasy feeling and is only supposed to work through the bottom half. When I use it I am constantly asked what I use on my hair because it smells and looks so nice. I consider this to be the ultimate compliment and would recommend this to anyone with dry or damaged hair that is suffering from hair breakage or split ends. It isn't an immediate fix, but after 3 weeks of using I was able to see some significant changes, with more drastic changes after a few months.

I love Redken Extreme Length Leave In Treatment! I've noticed less breakage and healthier ends. It makes my hair so soft and the smell is awesome.

Such an awesome leave in conditioner. Works very well, smells great!
Dana from NJ
I like this product it did seem to make my hair feel very smooth and moisturized. It didn't make your hair feel very dirty either. I haven't seen a drastic change in my hair but maybe overtime it would look differently. I would recommend this product for people to give it a try because it might work differently on different peoples hair.
Mandie P from Massachusetts
I have extremely damaged hair from years of overprocessing and coloring.
I definitely use a lot of heat tools and styling tools on my hair as well.
I cannot recommend this product enough! It helped to give me a soft and smooth finished look especially on my ends after a blow dry.
I now use this product after every wash and will continue to use it!

I am obsessed with the Redken Extreme Length Leave in Treatment! It has a very fresh clean scent and leaves my hair smooth and helps untangle after washing my hair. This lengthening treatment is great for styling hair and it is like a cream that helps with split ends and smoothness. The scent is great and feels like professional hair care!

I have straight hair and this product does not get greasy. It does leave a little bit of a shine to the hair. It is a bit thick. I would prefer a thinner consistency. It has a nice scent to it. After using it for nearly two months. My hair is not really longer or healthier. I don't think this product did much. It came in a squeeze bottle like lotion so a little does go on a long way. I am not one to wash my hair that much either.

The Redken Extreme Length Sealer is very similar to a leave in conditioner, but better. I used it mostly on the ends of my long hair to prevent and treat my dry split ends. It really did help to smooth them out, and gave them some added shine and manageability. I really love this for my long hair, especially before I was able to get it cut, because I felt that it really helped my ends from being too dry and unattractive. I'm not too sure about it helping with any hair growth or strength, but it does have great ingredients like soy protein and biotin to help with that as well. Honestly, I really liked that it made my hair feel softer and less frizzy which was great. I do tend to have thinner hair, but with curls, and I find that some curly hair products are too heavy for my hair. Surprisingly this product didn't weigh my hair down or make it look or feel greasy at all, which is why I would definitely consider repurchasing in the future, and I would recommend for others who have similar hair issues like me (dry split ends, frizzy hair, and wild unmanageable curls). I also like the cute teal packaging, and the smell was pretty good as well, but not my favorite. The only thing I didn't care for is that the silver designs on the bottle start to flake off after using it for a while, but I guess it's just normal wear and tear!

Having a bleached hair comes with the territory of split ends. I use this after shower and OMG this thing actually worked without weighing down my hair. Less breakage, sealing my split ends! Plus the biotin too!
Patty from Chicago
I like this treatment and have been using it as part of my hair routine. It leaves the hair feeling nice and nourished. I overall have long hair and have seen healthy growth over time.
Ashpal42 from Greenbrier, AR
I absolutely love this product. It doesn't leave my hair oily or with a film and the smell is AMAZING! Will be buying again and highly recommend
MS B from Ardmore AL
Just received my Redken products...I had formally used Olaplex which is a good product but I needed more...Redken Leave in Length Treatment is THE ANSWER!!! As my hair has been transitioning to Grey I had lowlights and highlights on multiple occasions with mid shift to length becoming overly dry from processing....I struggled with shampoos and conditioners ..last purchasing Aveda.
SORRY FOR THE LONG POST BUT I AM ESTATIC FOR THIS REDKEN LINE, BONDING SHAMPOO, CONDITIONER, AND LEAVE IN TREATMENT IS THE ABSOLUTE BOMB!!!
Brandyb123 from CCTX
Felt like I retained a good amount of my hair after washing, detangling and using the Redken Extreme Leave In Treatment. Hair was strong after blow drying, too!
Birdie101 from Indiana
I used this product every other day. A little goes a long way. It has a great smell and leaves my hair feeling soft and healthy looking. The only downside is that it is on the pricey side.
Kayla18 from Louisiana
I have been using this every time after washing and conditioning my hair. My hair is pretty wavy and on the days I don't want to do much with it I use this as a leave in conditioner to tame my frizzies and define my waves. The smell is also very refreshing and clean. It's a super lightweight formula that eaves you hair soft and bouncy, but also defined.
sweetcarolin_a from Miami, Fl
I have a lot of naturally wavy, yet thin hair and I really like the Redken Extreme Length system. The leave-in treatment makes my hair smooth and doesn't leave a residue. I've noticed that my hair is shinier, feels healthier, and resists the unrelenting Florida humidity when I add this last step. Hoping to see an increase in health, strength and length!
