This product is the icing on the cake for the new Redken biotin hair system for me. So I've got long, fine hair that is a bit damaged. I'm not keen on cutting it, rather have been in the market for new daily products to strengthen it and support growth. I find it totally thoughtful that Redken even included an after shower treatment for this system that does just that. This is excellent for keeping my hair detangled between shower days, especially underneath the back of my head where my hair gets the worst with tangles. Significantly less since I've begun using this daily. It smells great, is a texture flexible for all hair types. I did notice on days I left my hair to air dry rather than use the hair dryer that between this and my hair serum, there can be a slight filmy feeling left behind. But once it dries up and I brush it out that went away. I just began adjusting the amounts to figure out the perfect combo between the two for them to exist in harmony and that was a pretty simple process. Its hard to give an opinion on what are supposed to be the longer term effects from this product and the system in general. But as someone who has used the Redken brand and have had family use the brand my entire life, I one hundred percent trust that this product will do & help with exactly what they tell me it will.
Extreme Length Leave-In Treatment with Biotin has a nice light scent. I can't tell if it's powdery or floral. Just can't put my finger on it. As far as using it, it goes threw my hair nicely and didn't leave any kind of greasy or heavy feeling. The thing I didn't like about this leave-in treatment was when I let my hair dry, my hair felt dried out. I did not like the way it made my hair feel. I couldn't run my fingers threw my hair without them getting caught. I used the REDKEN Extreme Length Leave-In Treatment with Biotin with the REDKEN Biotin Extreme Length shampoo and with the REDKEN Extreme Length Conditioner with Biotin.

I use this product after a good shower and then I use it and put a dime size amount on towel dried hair

Definitely has helped my hair grow.

This is fantastic! This is the best leave-in treatment I have tried, and I have tried a lot of them! Even adds some body to your hair with out having to blow dry.

Smells great! Ultra concentrated. My hair is already long, feels much stronger only after a few uses.

I have curly thin hair that is highlighted about every 4 months so the ends of my hair can get very dry and frizzy. I have used the shampoo, water, and leave in conditioner for about a week now and my hair has done a 360. It's not frizzy, it's soft, and my shine has come back. I'm not one to write reviews but I was so impressed with these products I felt these products deserved a 👍🏼. If you want a product that actually does what the product description claims then try it. You won't be disappointed.

This is a great product. I bought it as a lengths treatment but it's more versatile than what it says on the bottle. I have fine strands and lots of them, and long hair that gets frizzy. It cooperates well with my hair oil (Oribe Gold Lust), and it really brings out my hair's natural wavy texture. If I put it on wet hair, it dries with texture, and when I put it on dry hair it revives texture and adds extra movement and frizz control.

Yasmar from Winter Springs Florida
I got this product after being recommended by my hair dresser. So far, I love it. I have to say that it does leave my hair super soft and it makes it easier to detangle

Since social distancing started in March I've been growing out a pixie. I'm avoiding getting a haircut and this treatment has been the perfect addition to my routine! My ends had been feeling dry and brittle and looked a little out of control. I use the treatment after washing and towel drying my hair, between a dime and nickel size amount on my very thick bob length hair. I'm just over a week into using it and I've seen a tremendous difference in my hair! It looks like I had recently had a haircut (I haven't since the end of January), my hair is soft and smooth and much more manageable. Plus it smells great! Highly recommend.
Marie from Texas
Pro: great smell
Cons: makes SO much hair fall out (that alone is enough to return), too expensive for not working and making my hair worse than when I started using the entire extreme length system, and this product made my hair feel dirty and not smooth.

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 am so impressed with this product. After just one use I could tell a noticeable difference in the health and appearance of my hair. I used to swear by It's a 10 for years...but this product has it beat! I highly recommend and will only be using this product!!
Amanda M from Wisconsin
I got this product for free! I took advantage of the buy 2 redken products get one free. I love this stuff because it's really helped my hair feel softer and it makes it feel thicker. The solution itself is thick, but only a small amount is needed which assures me I will have this product for awhile.
Natalia from Detroit
After one use I immediately noticed a difference in my hair. My hair is long, about 5 inches past my shoulders. I am growing it out even longer, but like anyone knows, the longer the hair, the more damage it will have and the more care it needs. Once dried, my hair felt thicker. It also did not feel as damaged. I was worried about a greasy residue, but there was none. I have not used the shampoo and conditioner (as I color my hair and use their color system products for that), but now I am very tempted to use this whole collection. I have used other biotin based products and was dissatisfied, but this really is a game changer.
Amber from IA
I bought the entire system, and none of it worked well. I would just avoid it all together. The system leaves my hair feeling dirty and sticky.
Mia22 from Stamford ct
This makes my hair shine my hair is long past shoulders and this is worth the money.
No frizz at all, leaves hair so soft
Karla from Los Angeles
I use this after I shower on damped wet hair. Leave any hair soft.
Alex from Pittsburgh
I've been using the Redken All Soft for a while and I read some reviews about this one because I'm trying to get some length back. My friend owns a salon so I asked her opinion and she said this is the BEST for growing out hair because it literally stops split ends from happening. She did tell me to get the whole system, shampoo, conditioner and leave in treatment which I did and I've been using for 2 weeks and it makes my hair feel unreal! Not soft in a way a good conditioner does but like, silky smooth baby hair. And I dig the scent. It's light and not super strong after you dry your hair.
Cal from California
Easy to apply and adds an extra layer of hydration and protection.
