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 ...

Shampoo good, Conditioner perfect, but I still need answers
Hair Type Wavy Hair
I recently tried the Redken Extreme Lengths Shampoo and Conditioner, and I have mixed—but mostly very positive—thoughts. First, the scent of both the shampoo and conditioner is absolutely delicious. It's a sweet, yummy fragrance, but it isn't overpowering at all. As someone who is sensitive to scents, I really appreciate how pleasant and gentle the smell is. It makes washing my hair feel like a little treat without triggering headaches or irritation. The shampoo works well, but it's a bit strong for my hair type. I have fine, thinning, wavy hair that needs frequent washing, and this shampoo feels a little too intense for me to use every time I wash. For my hair, it works better as a weekly shampoo rather than a daily or frequent one. Now the conditioner is a completely different story—it is absolutely divine. I have tried countless conditioners over the years and have honestly spent thousands of dollars trying to find the right one. This conditioner takes first place over every other conditioner I've ever used. I love that it's silicone-free and alcohol-free, and it feels incredibly lightweight. It doesn't weigh down my fine, thinning hair at all, which is rare. My hair feels soft, light, and healthy after using it. For my hair type, it's honestly perfect. The only issue I've had is trying to get clear information about the ingredients. I've reached out to Redken several times—both by email and phone—to ask about this but haven't received a clear answer. There is no protein listed on the bottle's ingredient list, and when I copied the ingredients into several ingredient-checking apps, none of them identified any proteins. This actually makes me very happy because I am protein-sensitive, and protein in hair products usually causes problems for my hair. However, the website advertises the product as using "soy protein technology." This is confusing, and I would really love clarification on whether this shampoo and conditioner actually contain soy protein or not. If someone from Redken could please clarify this, I would greatly appreciate it. Regardless of the confusion about the protein claim, I still absolutely love the conditioner and would highly recommend it to anyone with fine hair looking for a lightweight option.
I love the way my hair feels after the first time

Secret to Stronger Strands Shampoo
Hair Type Straight Hair
My college daughter is loving this product. She has used the Redken Extreme (strength repair) and liked it before so this line was definitely something she wanted to try. She can't wait to see how this product will strengthen and help with length because we know Redken products do what they say they'll do!
Not for me
Redken products. This one however fell really short for me. Unfortunately it made my hair feel very processed, dry and much like brushing through a ratted barbies hair. It did the samd to my daughter.

- Q
Is this sulfate free?
- Asked by Lexie
- Official Answer By Redken - BEno, Redken Extreme Length Shampoo is not sulfate-free—it does contain sodium laureth sulfate to help create a rich lather and cleanse the scalp. If you specifically need a sulfate-free option from Redken, you'll want to check out lines like Acidic Bonding Concentrate or Color Extend Magnetics instead!Was this answer helpful to you

Hello i have short curly hair. I am planning to buy shampoo and conditioner. Do i have to but the mask and leave in treatment for this or is it optional. Whats the results if i do and dont?
- Asked by Anelys
- Official Answer By Redken - BEThe mask and leave-in treatments are completely optional—starting with just the shampoo and conditioner will give you a great foundation of basic strength and cleansing, while adding the full routine provides maximum repair and protection against breakage. However, since you have curly hair, keep in mind that the Extreme line is heavily focused on protein; if your curls are mostly in need of moisture, you might want to consider a hydrating collection instead to keep your curls soft and bouncy!Was this answer helpful to you

Is this line color safe? My color lifts easily, and I need color safe guaranteed.
- Asked by michelle
- Official Answer By Redken - BEHi there! Yes, Redken Extreme Length Shampoo is suitable and safe for color-treated hair. Our Extreme Length system (formulated with Biotin and Castor Oil) is specifically designed to fortify and strengthen damaged or chemically treated hair, helping you prevent breakage so you can reach your length goals without compromising health. However, because you mentioned your color lifts easily and you are looking for a guaranteed color-protection guarantee, we want to share a quick recommendation: For maximum color longevity: While Extreme Length is safe for color, it is primarily formulated for strength and growth. If preserving delicate or easily faded color is your top priority, we recommend Redken Color Extend Magnetics Shampoo or Redken Acidic Color Gloss Shampoo. Both of these lines are 100% sulfate-free and engineered specifically to lock in color vibrancy, seal the cuticle, and prevent premature fading. If your primary goal is growing longer, stronger hair that has been weakened by color services, Extreme Length Shampoo is a great choice! Feel free to consult your Redken stylist to tailor the perfect routine for your specific color needs.Was this answer helpful to you
- Q
Would you recomend using this product after using the Redken Pink Volumizing Shampoo/Conditioner? I would try to like a new shampoo just becuase I have used the pink bottle for almost a year now .
- Asked by Jocy
- Official Answer By Redken - BEHi there! Absolutely! We definitely recommend trying Redken Extreme Length Shampoo! It’s a fantastic choice, especially if you're looking for a change after using our Volume Injection line (the pink bottle). Switching up your routine is a great way to give your hair a fresh boost. While Volume Injection is formulated to add instant body and root lift, Extreme Length Shampoo (infused with Biotin and Castor Oil) focuses on fortifying your hair structure to prevent breakage and help you achieve longer, stronger, and healthier-looking hair. Pro-Tip for exact customization: You can even mix and match! If you still love the weightless body from your Volume Injection line, try pairing the Extreme Length Shampoo with your Volume Injection Conditioner, or alternate between the two routines depending on whether your hair needs extra strength or extra lift on a given day.Was this answer helpful to you
- 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
