How to Use
Rated 3.51 out of 5 stars
I'm 25, caucasian, with naturally wavy hair and I really like the Redken Extreme Length system. I love the scent- it's not overbearing at all. The shampoo lathers well, I just feel like it's more watery/not thick- but maybe that extends the use since the bottles are only 10oz and 8oz. The conditioner may not feel like you're using enough, but I can tell that I'm using the right amount for me when I can easily comb through after applying. I love rinsing the conditioner out because my hair feels so smooth. The leave-in treatment makes my hair smooth and doesn't leave a residue. I love the system overall, and I've noticed that my hair is shinier and feels healthier. Hoping to see an increase in health, strength and length!
I bought the shampoo and conditioner from this line. The conditioner works fine and leaves my hair silky. The shampoo is a different story, however.. (only put conditioner on mids-to-ends, so shampoo is the only product that touches my scalp). I usually wash my hair every 5-7 days as it does not get greasy easily. With this shampoo, however, it starts getting greasy the next day after washing it! I have been using it for 1.5 months now since I thought that maybe it would take some time getting used to it, but nope, my scalp is still itchy and my hair gets greasy really fast. Will never be using this again.
As for hair growth, I have not noticed any differences, but I also have only used it for a month and a half.

I bought this thinking it would help maintain my long hair healthy. I have thin hair and as soon as I started with this shampoo it made it extremely greasy… now my hair hasn't been able to recover after that… had to get a clarifying shampoo after this and it is not getting any better. Extremely sad.

This product along with the conditioner made my hair SO DRY. My hair felt thin as ever with only four washes.
Jess from Minnesota
Left my hair really clean and smelt good. Definitely made my hair fall out more than normal. Not sure if it's the change in season adding to how much fell out but would not recommend this product
Lis from Pennsylvania
I had bought this maybe less then 4 months and lasted for a good while. My goal was hoping it would grow out my hair since I was noticing that I was balding from postpartum although it gave me length but wasn't making it fuller it actually made my hair thinner. I had also bought the leave in conditioner that goes with this brand to help my split ends and that wasn't working either just made my hair extremely dry and more split ends. Don't waste your money.
Hanna from Dallas
I bought this during the sale and just used it tonight and literally after a double wash and condition with redden extreme length line my hair is sooo soft and insanely shiny. I've been looking for something to help my damaged bleached hair and this line is it.
Venus from Joshua Tree
I'm half way thru a 33oz bottle that I purchased back in June. I used once a week and still grew a couple of inches in a few months. At the end of September I cut off 14 inches I shampoo everyday and have grown 3 inches and the over thickness all over my head had doubled. even each hair strand is thicker. Highly recommend. I have virgin hair so that might help too.

Hello bald spots and hair loss. I will never buy any redken product ever again. Whatever is in this is toxiccccc
Curly Q from Los Gatos
My niece and I both used this this morning (December 24th) and each of us have cuts on our hands after opening. We checked the top and nothing LOOKS sharp, but we have the same thin deep cut, but on different fingers

This shampoo left a sticky film on my hair after using it and rinsing thoroughly. Even my hair stylist noticed. I will be returning

After only 3 uses, I noticed my hair was coming out in large amounts & you could see a lot more of my scalp. I've never used Redken before, but heard a lot of good things. I got a bad hair cut & was trying to find a shampoo that would help my hair grow back a little faster. This did quite the opposite. I've never been more devastated! Save yourself the heartache & DO NOT BUY THIS PRODUCT!
Taylorb from Kentucky
After going platinum blonde my hair started to get very tangly during the shampoo process (which is a massive pain and I started to hate to wash my hair) while I have only used this shampoo and matching conditioner twice I can tell you that my hair was not a tangled mess after shampooing! Even after the shower after I applied my leave in products it was way more smooth and easier to use my wet brush! So far I am loving this combo and will continue to use and hopefully on the road to growing my super bleached hair longer!
Jayline from Fresno,CA
I bought this shampoo after using the all mega soft conditioner (that i fell in love with) hoping that i would love it as well, sadly that wasn't the case. I noticed that my hair felt dry after using this shampoo. As for the smell it isn't extremely unpleasant but it isn't good either.

Redken is a great product. I just started using this particular shampoo & conditioner. I already see a smoothness & fullness in my hair.

I started losing a lot of hair after using this shampoo. I stopped using it and am not losing ridiculous amounts of hair anymore. I don't know why this shampoo causes this, but from reading other reviews I am not alone. Making me question using redken products!
AJ from Cincinnati
I have curly bleached hair that's pretty damaged so I can never get it to grow. This is the only product that grew my hair soooo fast! I let the conditioner soak for 5 min then use olaplex no. 6 when I get out of the shower. It's also helped my hair thicken and I have so much new growth coming in!!
Josie from California
I used this one time and it made so much of my hair fall out. I was literally just running my hands through my hair pulling out chunks. Returning it asap. I unfortunately didn't look at reviews since redken is such a well known brand. But other girls on here say they had the same problem. Definitely stay away from this one.
KW from Knoxville, TN
Great shampoo! I use it with the conditioner and it makes my hair feel super soft! I had tried several different shampoos for my hair but this one is by far my favorite. Plus my hair doesn't feel greasy like other shampoos I've tried! I also have a lot of dandruff especially in the winter but this shampoo keeps that to a minimum!
Jim from Portland
It has sulfate in it and I have curly hair don't use this product 🤦🏽♀️ Very disappointed
Penny from Winchester, VA
I wash my hair with it.

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.
Long hair don't care from California
Use this shampoo with all soft conditioner and thank me later. When I used just all soft shampoo and conditioner, my hair felt too heavy. With I used this shampoo and conditioner, my hair felt too dry! Using this shampoo with all soft conditioner together is like the perfect blend! My hair is super soft, silky, and not dry or heavy at all! Also, only after using this combo for a week, there is a very noticeable (approximate) 90% less hair fall! I am so glad I decided to try this because it's the perfect combo for me! For reference, I have fine wavy hair, but I have a lot of it.
Libby from Arkansas
I have fine straight long hair, and even though it's fine I have a lot of it! I have always been told my hair is shiny, even when I was at summer camp! I have used the all soft, extreme & I just picked up the new pink volume conditioner. Definitely a good product!
Shosh from AK
I have fine blonde hair that is prone to breakage, and my scalp and hair is definitely more oily than dry. In December 2020, I had my first salon haircut in a year, and the hair dresser cut my hair much shorter than I asked for. I had wanted a shoulder length long bob with sideswept bangs; she gave me jaw length and no bangs. I was desperate to grow it back out quickly. With this shampoo and conditioner, my hair was past my shoulders again by June so I was able to see a different hairdresser to get the shape corrected and have highlights and lowlights added. 3 months after that second cut, it's a few inches past my shoulders again and looking so healthy! My breakage is greatly reduced, and this shampoo cleanses well. I usually wash my hair every other day, and I've been so pleased with my first Redken experience.
