For best results, use Redken Extreme Length Shampoo with Biotin as part of your regular haircare routine.

Step 1: Cleanse with biotin shampoo Apply a small amount of Redken Extreme Length Shampoo to wet hair. Massage into the scalp and lengths to create a rich lather, then rinse thoroughly.

      We are so sorry to hear that our Frizz Dismiss Rebel Tame didn't work for you. We know how disappointing it is to invest in a product that doesn't deliver the results you hoped for. Because Rebel Tame is our richest, most intensive smoothing cream, it is formulated with a heavy concentration of Babassu Oil. While it works wonders for extremely coarse or thick hair, it can unfortunately weigh down, coat, or feel heavy on fine-to-medium hair textures.

      [This review was collected as part of a promotion.] I bought this shampoo because I am trying to grow out previously blonde hair that is now brunette, but still color treated to cover gray. This shampoo left my hair soft, but not flat, and feeling clean yet not stripped and squeaky. It has a nice, but not overpowering fragrance.

      This is one of my favorite products. When trying to find a system to support hair health and growth, extreme lengths went above and beyond my expectations. My hair dresser was floored to see the restoration that took place over 6 weeks and even more so after 12, my hair was healthy and growing again!

      Yes, I recommend this product.

      I absolutely love the extreme length shampoo and conditioner! My daughter introduced me to it and I received my order last week. What a difference in just one use. My hair is long and I am in my mid 60’s. I have gotten so many compliments on the condition of my hair! I am a Redken user for life. I’m excited to try other products in the Redken lineup.

      Yes, I recommend this product.

      I have 4a/b hair prone to dryness. It works REALLY good in my routine. I’m not sure if it’s helped my hair grow but it makes my routine so much quicker. And my hair last way longer in between wash days without getting to dry (4-5 days). I do recommend using a clarifying shampoo first and then using this Redkin shampoo. I know it more money but I double wash anyways to promote growth, so it works in my routine.

      Yes, I recommend this product.

      I love redken, and have been waiting to leave a review. Back in July my hair stylist recommended this shampoo. My hair was to my waist and was wanting to see how long it could get, also super thick hair. After 1 month of this shampoo it broke my hair and I experienced severe hair loss. It is now January and my hair is finally starting to heal from this, my hair had to be cut to my shoulders. Super sad this happened to my beautiful hair and just use this product with precaution. Please know your hair. During that one month it was doing very well until it wasn’t. I would definitely have upload pictures but it wouldn’t let me.

      No, I do not recommend this product.

      Learn More About Redken Extreme Length Shampoo with Biotin

      What can you use to make your hair grow longer?

      To encourage hair that looks longer and healthier, focus on products and habits that help keep your lengths strong. Using a gentle shampoo and conditioner, minimising heat, brushing carefully, and protecting your ends all help reduce the appearance of breakage so hair can reach its full potential. Regular trims also make a difference by keeping ends looking neat and preventing frayed lengths from travelling upward.

      If you’re building a routine around longer‑looking lengths, the Redken Extreme Length system: featuring Redken Extreme Length Shampoo with Biotin, conditioner and leave‑in treatment, helps reduce breakage so hair appears stronger as it grows.

      Does biotin shampoo help with hair growth??

      A biotin shampoo like Redken Extreme Length Shampoo can help reduce the appearance of breakage and split ends, which make hair look longer and healthier over time. While it doesn’t alter how fast hair grows from the scalp, it helps keep lengths intact so you can maintain the look of longer hair more easily.

      Can you use Redken Extreme Length Shampoo everyday?

      Yes, Redken Extreme Length Shampoo with Biotin can be used daily if that suits your hair and scalp. It provides a gentle cleanse while supporting stronger‑feeling lengths. If you wash less frequently, simply use it each time you cleanse as part of your usual routine.

      Is Redken Extreme the same as Extreme Length Shampoo?

      No, they are designed for different hair needs based on whether your priority is general damage support or maintaining longer‑looking strands

      Redken Extreme shampoo supports hair that feels weakened from chemical or mechanical stress.
      • Extreme Length Shampoo with Biotin is formulated to help reduce the appearance of breakage along the lengths for those wanting longer‑looking hair.

      How often should you use Redken Extreme Length Shampoo?

      Use Redken Extreme Length Shampoo as often as you normally wash your hair. Daily washers can use the shampoo and conditioner every day, while those who wash less frequently can use it whenever they cleanse. Consistent use of the full system helps maintain stronger‑feeling, longer‑looking lengths.

      Is the Redken Extreme Length shampoo good for low porosity hair?

      Low porosity hair has tightly closed cuticles that can make it harder for moisture to enter. Extreme Length Shampoo with Biotin offers a gentle cleanse and strengthening support that can work well for this hair type when paired with the matching conditioner. Apply shampoo mainly to the scalp, rinse thoroughly, and use a light amount of conditioner on mid‑lengths and ends.

      If you’d prefer a routine that focuses more on lightweight moisture for low‑porosity hair, the Redken All Soft Shampoo is a great option to help add softness without weighing hair down.

      Is Redken Extreme Length shampoo good for high porosity hair?

      High porosity hair has cuticles that are more open, which can make it feel dry or fragile. Extreme Length Shampoo with Biotin can support this hair type by helping reduce the appearance of breakage and keeping lengths feeling stronger. For best results, follow with a generous amount of the matching conditioner and finish with the Leave‑In Treatment to help smooth the look of porous strands.

      If you’re looking for a routine designed specifically for highly sensitised or very processed hair, the Redken Acidic Bonding Concentrate Shampoo offers strong support for the look and feel of high‑porosity strands.

      Is biotin shampoo good for hair loss?

      A biotin shampoo like Redken Extreme Length Shampoo with Biotin helps support stronger‑feeling hair and reduce the appearance of breakage, which can make lengths look fuller and healthier. It isn’t a treatment for hair loss, but it can be a helpful part of a routine focused on maintaining the look of longer and stronger hair, which will also make hair look thicker.

      Is the Redken Extreme Length shampoo good for fine hair?

      Extreme Length Shampoo can work for fine hair that’s prone to breakage, especially if you’re focused on growing your hair longer. Use a small amount at the scalp, follow with a light application of conditioner through mid‑lengths and ends, and keep leave‑ins minimal to avoid weighing hair down.

      If your main goal is fuller‑looking, lifted hair, a volumising routine may be a better match. The Redken Volume Injection Shampoo is formulated with Filloxane to help create a fuller, more bodified look without adding coarse texture.
