Redken Extreme Shampoo is made for hair that feels weak, brittle, damaged, or prone to snapping from bleaching, coloring, heat styling, or mechanical stress.
Its current formula combines a fairly effective cleansing system with arginine, amino acids, hydrolyzed soy and vegetable proteins, citric acid, dimethicone, and conditioning ingredients.
My overall Redken Extreme Shampoo review is positive for breakage-prone hair. It can make damaged strands feel stronger, smoother, and easier to manage. But it is not the best choice for every dry-hair problem, and people who overuse protein-rich products may eventually find their hair feels stiff or rough.

My Experience With Redken Extreme Shampoo
I started using Redken Extreme Shampoo at a time when my hair was crying out for help. Frequent styling and coloring had left my hair looking dull and lifeless. Here’s how my experience unfolded over several weeks of use.
- Week 1: Initial Impressions
The first thing I noticed was the shampoo’s pleasant, mild fragrance. It wasn’t overpowering but gave a fresh, clean scent that lingered for a while. The texture was creamy and lathered well, even with a small amount. After rinsing, my hair felt clean but not stripped of its natural oils.
- Week 2-4: Visible Changes
By the second week, I began to notice subtle changes. My hair felt stronger and looked shinier. There was a significant reduction in breakage, especially when brushing or styling. The shampoo seemed to add a bit of volume, making my hair look fuller and healthier.
- Week 5 and Beyond: Long-Term Effects
After a month of consistent use, the transformation was undeniable. My hair was no longer brittle and felt more resilient.
Split ends were less noticeable, and there was an overall improvement in texture and manageability. The shampoo lived up to its promise of strengthening and repairing damaged hair.
Pros of Redken Extreme Shampoo
Let’s talk about the positives, which definitely made me a fan of this product.
- Strengthens Hair

Redken Extreme Shampoo does an excellent job of fortifying weak and damaged hair. The protein-infused formula delivers on its promise, leaving hair stronger and more resilient.
- Reduces Breakage
One of the most noticeable benefits for me was the reduction in hair breakage. I could see fewer strands of hair in my brush and on my bathroom floor.
- Improves Hair Texture
The shampoo made my hair feel smoother and softer to the touch. It was easier to manage and style, which was a significant plus for my hectic mornings.
- Pleasant Fragrance
The mild, pleasant fragrance was a welcome change from some other shampoos that have overpowering scents. It left my hair smelling fresh without being overwhelming.
Can Redken Extreme Actually Repair Damaged Hair?
It can improve damaged hair significantly, but it cannot biologically heal a hair strand.
Hair outside your scalp is nonliving keratin fiber.
Once it has been severely damaged by:
- Bleach
- Heat
- Chemical processing
it cannot regenerate itself like skin.
Hair products instead work by:
- Coating damaged areas
- Reducing friction
- Adding conditioning
- Reinforcing weak sections
- Improving flexibility
This can make damaged hair behave much more like healthy hair.
That is meaningful repair from a cosmetic standpoint, even though it is not permanent regeneration.
Cons of Redken Extreme Shampoo
While I had a largely positive experience, there are a few drawbacks worth mentioning.
- Price Point
Redken Extreme Shampoo is on the pricier side compared to other brands. If you’re on a tight budget, this might be a factor to consider.
- Protein Overload
While the protein content is beneficial, using too much protein can sometimes lead to hair feeling stiff or dry. It’s important to balance it with moisturizing treatments.
- Availability
Depending on where you live, finding Redken Extreme Shampoo can be a bit challenging. It’s not always available at every drugstore or supermarket, which might be inconvenient.
How Often Should You Use Redken Extreme?
There is no single schedule for everyone.
If your hair is heavily damaged, you may use it as your regular shampoo initially.
If your hair is only moderately damaged, you might use it:
- Once or twice per week
and alternate with a moisturizing cleanser.
If the hair begins feeling:
- Stiff
- Rough
- Straw-like
reduce the protein-focused products.
How to Use It?
Redken’s current directions are simple:
- Wet hair thoroughly.
- Apply shampoo.
- Massage into a lather.
- Rinse.
- Follow with Extreme Conditioner.
- Add Anti-Snap treatment if desired.
Concentrate shampoo mainly on:
- Scalp
- Roots
rather than repeatedly scrubbing damaged ends.
The rinse water is usually enough to cleanse the lengths.
Comparing Redken Extreme Shampoo To Other Brands
To give you a well-rounded perspective, let’s compare Redken Extreme Shampoo with a couple of other popular brands known for addressing damaged hair.
Redken Extreme Vs. Olaplex No. 4 Bond Maintenance Shampoo
- Formula and Ingredients: Both shampoos are designed to repair and strengthen damaged hair, but Olaplex focuses on bond-building technology, which works at a molecular level to rebuild broken bonds. Redken uses a protein-based formula.
- Effectiveness: In my experience, Olaplex No. 4 is slightly better at making hair feel smoother and more hydrated, whereas Redken Extreme excels in providing strength and reducing breakage.
- Price: Olaplex is generally more expensive than Redken, which might be a deciding factor for some users.
Redken Extreme Vs. Pureology Strength Cure Shampoo
- Formula and Ingredients: Pureology Strength Cure Shampoo is sulfate-free and contains keravis and astaxanthin to strengthen and repair. Redken Extreme contains proteins and lipids for fortification.
- Effectiveness: Both shampoos are effective, but Pureology tends to be gentler due to its sulfate-free nature, making it a better choice for color-treated hair.
- Price: Pureology is also on the higher end of the price spectrum, similar to Redken.
Who Should Buy Redken Extreme Shampoo?
I would recommend it if:
- Your hair breaks easily.
- You bleach or highlight regularly.
- You use frequent heat styling.
- Your hair feels weak rather than simply dry.
- You want a salon-quality protein shampoo.
- You have fine damaged hair that gets weighed down by heavy moisturizing shampoos.
Who Should Skip It?
I would choose something else if:
- Your hair is healthy but naturally dry.
- Your curls dislike sulfates.
- Your hair becomes stiff with protein.
- You avoid silicones.
- You want a sulfate-free color-protecting shampoo.
- Your main issue is scalp dandruff rather than hair damage.
FAQs About Redken Extreme Shampoo
Using Redken Extreme Shampoo daily might not be necessary or ideal for everyone, especially if your hair is not extremely damaged. It’s packed with proteins, which can lead to protein overload if used excessively. I found using it two to three times a week was sufficient to see significant improvements in my hair’s strength and texture.
While Redken Extreme Shampoo is excellent for strengthening and repairing damaged hair, it doesn’t directly promote hair growth. Healthy, strong hair is less prone to breakage, which can create the appearance of fuller, longer hair over time. However, if you’re specifically looking to enhance hair growth, you might want to consider products specifically designed for that purpose.
Redken Extreme Shampoo offers numerous benefits, including: Strengthening weak and damaged hair, Reducing breakage and split ends, Improving hair texture and manageability, Adding a healthy shine to hair, Providing a pleasant, mild fragrance.
Redken Extreme Shampoo focuses on strengthening and repairing damaged hair with its protein-infused formula. It’s designed to fortify hair from within, making it more resilient and less prone to breakage.
Redken Extreme Length, on the other hand, is formulated to help you achieve longer hair by strengthening it and reducing breakage. It contains biotin, which is known to support hair growth and overall hair health. If your goal is to grow your hair longer, Extreme Length might be the better option, while Extreme is ideal for repairing and strengthening.
Final Verdict: Is Redken Extreme Shampoo Worth It?
After using Redken Extreme Shampoo for several weeks, I can confidently say that it’s a solid choice for anyone dealing with damaged hair. It strengthens, reduces breakage, and improves the overall texture of your hair.
However, it’s essential to balance it with moisturizing treatments to avoid protein overload.
If you’re willing to invest in a high-quality shampoo and need something to rescue your damaged hair, Redken Extreme Shampoo is worth considering.
However, if you’re looking for a more budget-friendly option or need something specifically for color-treated hair, exploring alternatives like Pureology or Olaplex might be beneficial.
