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 ...

Never stop making this please!
I wish I could upload photos so everyone can see what I'm about to say. I started using this product in july after I had k tips removed that ruined my hair, and I took photos just to be able to see if any progress was being made. I took one this morning and ive also had one haircut to get my fringy dead ends off and nothing else done in between. Not only is my hair longer even after a cut, but the color is more vibrant and my hair is so much shinier and silkier. I really cannot believe the dramatic difference this has made for me. I was afraid because some reviews say the protein dries their hair out but it did not for me and I have naturally curly hair with drier looking ends. 10/10 recommend.
Doesn't help grow or strengethen hair. Don't buy.
People buy this because they think it will grow your hair, it doesn't. It doesn't contain any ingredients that promote hair growth, and I didn't notice my hair get stronger either. My hair felt oily/waxey after washing, Don't buy it, its not good.
Satin soft results
I have mixed curly hair that I'm growing out. Years of highlights have made it coarse. I only wear my hair straight. I regret that I've been sleeping on this line!! I bought and tried it today and it made my hair feel satin soft and SLEEK. I also used the conditioner and the split end balm. I used the Kenra silkening cream for heat protection and only had to use my straightener on 380 when I usually need 400-420. Other Redken lines havent worked well for me before but I'm so glad I tried this one. It's AMAZING. I think if you heat style frequently, you have to try this. Going to stock up!!

It made my scalp dry and itchy.
Make my hair thin and fall out way too much
I brought the shampoo and conditioner because I heard great things about it from 2 of my coworkers however, I only wash my hair 2 time away and I noticed after 3 months of use my hair falling out ALOT, now it's thin. I wish I could return it.

- 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
- Q
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
