    This shampoo and conditioner changed my hair texture a bit. It’s done back to my normal texture, but I think my hair suffered from protein overload.

    No, I do not recommend this product.

    We’re sorry the shampoo and conditioner left your hair feeling different. Hair can respond differently to formulas, and we appreciate you sharing that it returned to its usual texture after you stopped using them. Thanks for the feedback.

    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.
