My Fave!!
About 9 months ago I was sent this shampoo, conditioner and leave in treatment to review by a third party company. I have to admit, the first thing I noticed was the scent. It's marvelous!! The second thing I noticed is that after a couple of uses, my hair didn't break near as much. There wasn't a l...

Scent is wonderful, overall product not as much
I received this product to try for free in exchange for sharing my opinion about it. I have fine hair that lacks volume, as well as certain pieces that don't really seem to be growing at all, so I was very excited to try this product. The first thing that I noticed about it was the scent. Wow! This ...

Pleasant surprise
Hair Type Wavy Hair
I was actually sent this by mistake in my shipment, but I was able to keep it, thankfully! I fell in love this shampoo. I'm surprised it's rated so low. It has that great salon smell, and it makes my hair so soft and clean (and it's hard to find a shampoo that does both!). I had previously been using more "clean ingredient" brands, which I found very drying. This brought my hair back to life.
I do buy this product again and again.

I have been buying this product for years now and I have tried to change here and there but nothing compares to this Redken Extreme shampoo and conditioner. It may seem like it costs more but it really doesn't for as long as it lasts. You will love it
I would buy this product again
The product makes your hair very soft and also smells great.
Gets the job done!

I love this shampoo for hair lengthening! My hair has grown soo much! I would say it can be a little drying, so I would recommend a deep conditioner or a glossing product!
Has helped a lot with growth!
Hair Type Wavy Hair
Truly a great product! I pair it with the all soft conditioner and or a hair mask and I love the results thus far! I dont use it all the time but probably about once a week, and have still seen great results!

- Q
What does shampoo smell like?
- Asked by Liz
- Official Answer By Redken - BEHi there! Redken's Extreme Length Shampoo features a delightfully sweet, fresh, and uplifting fragrance! Officially, its scent profile is a beautiful Mixed Berry blend. When you use it, you can expect: Sweet & Sugary Notes: A warm, comforting base that many customers describe as smelling like soft marshmallow, vanilla, or spun sugar. Bright Fruity Accents: A cheerful pop of sweet berries and light citrus that makes your shower feel energized. Clean & Powdery Finish: A soft, "salon-fresh" dry-down that leaves your hair smelling clean and beautifully feminine long after your wash. It is a sweet and warm gourmand fragrance that is noticeable in the shower but fades to a lovely, subtle scent once your hair is dry!Was this answer helpful to you
- Q
Why does the Redken shampoos have such a strong scent to them? It flairs up my allergies. I have tried the one in the red bottle and the blue bottle.
- Asked by green eyes 777
- Official Answer By Redken - BEHi there! We are so sorry to hear that our fragrances have triggered your allergies. At Redken, we use professional-grade, signature fragrances in our formulas—including our blue bottle (Extreme/Extreme Length) and red bottle (Acidic Bonding Concentrate)—to deliver the luxurious, lingering "salon-fresh" experience that many of our clients expect. However, we completely understand that strong scents can be highly sensitizing for those with allergies or ingredient sensitivities. Because we want you to feel comfortable and safe using our products, here is how we can help: Full Ingredient Transparency: We list all fragrance components (like Limonene, Linalool, or Hexyl Cinnamal) on our bottles and product pages so you can cross-reference them with any known personal triggers. No Hypoallergenic Claims: Because we formulate for professional high-performance, Redken products are not classified as hypoallergenic or fragrance-free. We Want to Help You Directly: If you have a specific allergy or would like to share the details of your experience, please reach out to our Consumer Care team at 1-800-423-5280. We would love to help you find a more suitable solution or assist you further!Was this answer helpful to you
