This shampoo, conditioner, and deep conditioner were given to me for free from Influenster in exchange for my honest review. My hair is really fine and thinning, wavy and uncolored. I've been using these products for a few weeks now and have nothing bad to say about them, but nothing great either. My scalp feels healthy and normal, my hair clean and moisturized. The scent is mild, slightly herbal, which is nice compared to lots of other companies' overly-fragranced products. I can't think of any negatives, but it's just not giving me any particular reason to stay with it either. The special ingredients they advertise on the label are such small percentages, especially since these are products we wash out.

Upon receiving this box I instantly read the ingredients.. ouch after I was afraid to use it in my hair! I never put hair products that contain alcohol in my hair! Since I got this box for free to review I had no choice. Worst mistake of my life! I am a hairstylist and have lightened hair, this made my hair stick together and feel ultra dry as I was applying to my damp hair in the shower, I couldn’t even get a brush through it.. I used this in combo with the matching shampoo and mask… and my hair is still messed up three weeks after use. If you have lightened hair or fine hair I would steer clear of this line , it is absolutely awful, I have had better luck with drug store bought brands then this crap! I have been using my normal pureology products to try and nurse ... MoreUpon receiving this box I instantly read the ingredients.. ouch after I was afraid to use it in my hair!

I have big lips thanks to genetics, but they've been quite chapped and shriveled due to the cold. You can feel the plumping agent but it isn't painful like other plumping lip products. Im actually very sensitive to plumping agents and this is a nice warming slight tingling sensation. I got 2 colors and this is the one I tried on first. Just take care not to click it all the way up and only click up what you need and your packaging won't have a huge mess. If my big lips don't cause the packaging to become a huge mess, with a little bit of care yours shouldn't either. The reason it doesn't click down is because of how emollient the product is, it wouldn't click down without a huge mess and messing up the product, the packaging makes sense.

I do like the shine and the sparkle in the formula isn't crazy noticeable. Overall I really enjoy this and I'd suggest it if you're thinking about it.

I've always had long, wavy hair, and despite being magical mermaid hair, it is surprisingly temperamental, so for YEARS I've been on the lookout for my "perfect" conditioner! I feel like this one, is the closest I've come to finding the perfect conditioner! It has a fairly pleasant smell (not fruity... I can't quite place it... it's almost a vanilla? But with some other perfume on top). If you're sensitive to scents, definitely use the conditioner sparingly (it surprisingly goes a LONG WAY, so definitely use a little at a time!) I was afraid at first that it wasn't going to do my hair well, since my hair incredibly dramatic. After every use, my hair has felt luxurious! It feels like theres a coating over my hair, which at first felt weird, but its been protective of ... MoreI've always had long, wavy hair, and despite being magical mermaid hair, it is surprisingly temperamental, so for YEARS I've been on the lookout for my "perfect" conditioner!

It feels like theres a coating over my hair, which at first felt weird, but its been protective of each strand, and my hair has looked really nice in photos! My scalp has also been much happier, and hasn't had any buildup since using this product! I will absolutely be picking this up in the future!
Let me start by saying my hair has no dye or product in it so this product review is based on natural hair response. This is an impressive conditioner from Redken, geared toward length and strength. If those are two hair qualities you are seeking for yourself, then this is the hair line for you! Firstly, I love that this product has such a payoff, for so little a price to pay. I’ve tried conditioner from all price ranges, including the very expensive raved about MLM type brands. This Redken lengthen and strengthen beats that easily! This shampoo left my hair feeling quenched BUT not oily or heavy, which has been a huge problem for me. Most conditioner weigh my hair down and make it look too shiny. My hair feels fresh and bouncy, I’ve noticed significant improvements ... MoreLet me start by saying my hair has no dye or product in it so this product review is based on natural hair response.

This Redken lengthen and strengthen beats that easily! This shampoo left my hair feeling quenched BUT not oily or heavy, which has been a huge problem for me. Most conditioner weigh my hair down and make it look too shiny. My hair feels fresh and bouncy, I’ve noticed significant improvements with the movement and structure of my curls. The biggest payoff for me is that this product has helped my curls stay structured longer!! Previously my hair would dry curly and cute, but the curls would immediately fall or frizz out with a day/ponytail/sleeping. Not with Redken lengthen and strengthen though! I cannot believe how helpful this has been. I genuinely did not have any expectation of huge payoff and boy was I impressed! I see myself sticking with this haircare line for the foreseeable future.
Redken is one of my absolute favorite shampoos, conditioners and hair treatments. This brand literally has a shampoo/conditioner/hair product set for all hair types. 🔹So what’s the difference with this range? Well Redken Extreme Length Conditioner contains Biotin to help strengthen damaged hair and helps hair grow longer and healthier. It also helps hair from breaking and promoting your hair to grow stronger. It also works with color treated hair. 🔹First and foremost- the scent! It smells heavenly. Not too overwhelming but just enough. I felt my hair to be very soft and hydrated. No hair fallout (like some brands do to me). No irritation on my scalp. I did notice my hair to improve in the few times I have used it’s and incredibly soft it is and healthy looking.

Definitely recommend this range and brand to anyone seeking a good hair shampoo! 🔹I was gifted the Redken Extreme Length Conditioner in exchange for my honest review. My thoughts and opinions are my own.
I was really excited for the extreme lengths system because I have pretty fine, thin, breakage prone hair. I also feel like more recently my hair has been thinning. The Redken Extreme Length Conditioner is meant to be paired with the other products in the system- which I have been doing. I have been using the conditioner after shampooing and using the Triple Action Treatment from the Extreme Length system. I had anticipated after shampooing, using the treatment for 5 minutes, then conditioning, that my hair would feel heavy and weighed down. It doesn’t at all! It feels so silky and smooth both while wet and dry after styling! The scent is nice! I don’t LOVE it, but I also don’t hate it!! I would say it isn’t my style of fragrance- but the scent isn’t overpowering ... MoreI was really excited for the extreme lengths system because I have pretty fine, thin, breakage prone hair.

I would say it isn’t my style of fragrance- but the scent isn’t overpowering and doesn’t linger too long anyway, so I don’t mind it at all. Plus I’ll happily sacrifice the ideal scent for the way this system makes my hair feel! Then ingredients seem great! (I’m not one who usually is going over shampoo ingredients with a fine tooth comb anyway, but I know Biotin is good for hair growth so that’s a plus! I waited until the last minute to review because I really wanted to give a legitimate review of my experience. I’ve been exclusively using this line for 3 weeks and immediately after my first use, my hair honestly felt stronger! Everytime I use this system it feels like I went to the salon and got a cut. My hair feels lightweight, yet more dense if that makes sense? Very silky and smooth. I would definitely recommend this product to others, and actually already have! When mine runs out I will for sure be buying some more!
Much like my review on the shampoo, conditioner works just as well and adds so much moisture to my hair. Every other conditioner I tried has tried out or made my hair is super frizzy and almost deflated my curls. Yeah this conditioner does the exact opposite and brings so much life back to my hair! I’ve relaxed my hair many times since I was a child so the fact that one wash brings back all my natural curls astonishing! This shows that it’s going deep into the hair follicles and really bring my hair back to life like it should be. There isn’t much of a smell to this conditioner at which I do thoroughly enjoy because too much time can be a bit offputting.

And a little goes a long way so don’t think you have to put a lot in your hand to get through all your hair. Bonus fact is that since I recently colored my hair blue and green, bleeding happens frequently yet with the combination of the shampoo and conditioner the bleeding was minimal and did not strip any color out of my hair. So it’s safe to say that this set of shampoo and conditioner is definitely color safe!
I have thin, fine, wavy to curly hair and this is my favorite conditioner. I'm surprised by the negative reviews but I guess maybe it depends on each persons hair type. I have sensitive skin and am prone to scalp breakouts and this keeps my skin and scalp acne free. No breakouts or issues with sensitivity. It doesn't feel like it's building up and I've used it for months. I do think the matching shampoo is a bit too drying for me but I love this conditioner. It is moisturizing and strengthening for my hair. It keeps it soft and easy to comb out but doesn't weigh my hair down. My hair doesn't fall out any more or less than normal and I do see less breakage. I've used the big name salon products and curly hair products and this one is my favorite.

I'm really only giving 2 stars because the product smells nice. I have thin, fine hair that's mid back length. The conditioner didn't feel moisturizing when I applied it, almost feeling thick and tacky. I let it sit for at least 3 minutes. Washed it out. After towel drying, it was difficult to brush out considering I generously used the conditioner. I applied my usual thermal spray and blow dried. My hair was getting tangled as I blow dried. After it was completely dry I couldn't run my hands through my hair without pieces catching somewhere. Even some breakage. Overall my hair felt dry and dull. It didn't help with frizz or static. It was so bad I actually went back and rewashed my hair and used the product I was previously using. I have had good luck with Redkin ... MoreI'm really only giving 2 stars because the product smells nice. I have thin, fine hair that's mid back length.
