Q: I see a question about using this shampoo and conditioner every wash day for curly hair but what about pin straight hair? I wash my hair everyday, will I eventually suffer from protein overload due to the frequency of my hair washes?

Q: IS THE EXTREME LENGTH BIOTIN SHAMPOO AND CONDITIONER COLOR SAFE AND SULFATE FREE?
Fdez765 months ago
1 AnswerAnswer this Question
- A: Hi there! Thank you for your question about our Extreme Length Biotin Shampoo and Conditioner! To answer your questions: Is it color-safe? Yes, both the shampoo and conditioner are safe for use on color-treated hair. Is it sulfate-free? No, the Extreme Length Shampoo is not sulfate-free. It contains sulfates to provide a deep, thorough cleanse for the scalp and hair. If you are looking for a sulfate-free option within Redken, we highly recommend our Acidic Bonding Concentrate or Color Extend Magnetics ranges. We hope this helps you find the perfect routine for your hair goals!

Q: Can I use this every wash day? (about every two days) and should I only use it for a short amount of time? People are saying it’s causing protein overload and damaging their hair.
Abbiey8 months ago
1 AnswerAnswer this Question
- A: Yes, you can safely use Redken Extreme Length Shampoo every wash day, as it is professionally formulated with Biotin and Soy Protein to be gentle enough for frequent use without causing damage. The "protein overload" many fear is often actually a lack of moisture balance; because 3c-4a curls are naturally prone to dryness, the hair can feel stiff or brittle if strengthening treatments aren't paired with enough hydration. You do not need to limit your use to a short period, but for your specific curl pattern, the key is to ensure you are following up with a highly moisturizing conditioner or mask. This creates the perfect harmony between the strength provided by the Extreme Length line and the elasticity your curls need to stay bouncy and soft.

- A: Hi there, we do not believe that there should be any issue with using our products; however, since our products have not been tested in conjunction with Brazilian Keratin Treatments, we cannot provide you with usage information.

Extreme Length Shampoo is formulated with Strength Complex with Amino Acids and Arginine, delivering desired results. Citric Acid further balances hair pH for conditioning and smoothness.
