Redken Extreme Shampoo Review [Is It Good?]

Don’t we all hate damaged hair? It is a common problem that can constantly worry us.

People like me, who have porous, dry hair, struggle with hair loss as every strand of hair becomes fragile.

If you have tried every preliminary product like me but didn’t find the solution, change your shampoo. 

The extreme collection from Redken offers the perfect shampoos for damaged hair, so I had to use and review them.

Let’s dive into this Redken Extreme Shampoo Review and see what this product offers.

Redken Extreme Shampoo Review

Here are the products currently featured as part of the Extreme collection.

Redken Extreme Shampoo Review

1. Redken Extreme Strengthening Shampoo

This is the highest-selling shampoo from the extreme collection. This extreme shampoo is extremely popular.

It contains Amino acids and Arginine as active ingredients, which add a lot of strength and nourishment to my hair while treating any damaged strands.

This Redken Extreme shampoo eliminated split ends restored my damaged, brittle hair, and made it stronger, thicker, and healthy.

This incredible formula made my hair stronger and more beautiful with a glossy finish. 

However, it is only affordable if you purchase the bigger bottle, as the smaller one can hike the price to $2.5 per Fl Oz.

  • Improves damaged hair.
  • Increases thickness and volume.
  • Reduces split ends


  • Smaller bottles are expensive.

2. Redken Extreme Length Shampoo With Biotin

The active ingredient in Extreme length shampoo is Biotin. It is a vitamin that encourages hair growth and strengthens weak strands on the scalp.

This shampoo can have a long-lasting effect on your hair. Over time, you may notice faster hair growth due to the constant use of Biotin.

It also has a great smell that can help you stay refreshed throughout the day.

I have been using this shampoo for its refreshing smell and beneficial formula. However, it does contain some sulfates to create a lather.

Almost 25000 customers have given Extreme Shampoos a positive rating on Amazon. This resulted in 90% positive reviews and 4.6 out of 5.

It is safe to say that consumers around the world love these shampoos.

Many consumers on Amazon claim that the product significantly impacted their hair. It gave stronger, thicker hair and improved the damaged strands.

The Extreme Strengthening Shampoo is a product I use myself. I picked this shampoo because my hair is fragile and thin.

The strengthening effect reduced my hair fall and fortified my hair from deep down.

Customers worldwide had similar experiences as Amazon is full of positive reviews for Redken Extreme Shampoos.

Is Redken Extreme Shampoo Good?

Redken extreme shampoos are premium products. However, unlike most premium shampoos in the market, these shampoos are not very costly.

The regular 10.1 FL Oz bottle can be purchased at $25, while the 33.8 FL Oz bottle costs more than $45. This means you can save significant money if you buy the bigger denomination.

Many consumers who labeled the product pricey on Amazon reviews also bought the smaller bottle, which is a little expensive.

Redken Extreme shampoo’s good effects on hair make it worth every penny.

You will feel the same way by using this product and seeing the results yourself.

How Should You Use Redken Extreme?

Redken Extreme shampoo is a line of everyday products. All 3 shampoos from this collection can be used daily.

Take a small amount of extreme shampoo and apply it to your hair. Gently massage your scalp and create a lather to clean all the dust particles in your hair.

Wait a few minutes before rinsing to ensure the damaged strands absorb the healing shampoo formula.

Why Choose Redken Shampoo? 

Why Choose Redken Extreme Shampoo

Here are some reasons why extreme shampoos are so effective and worth trying.

Strengthens Weak Hair

There is no doubt that the Redken Extreme Shampoo collection improves damaged hair while increasing its strength.

Many consumers use it on fragile hair to get rid of weak hair once and for all. 

Extreme shampoos nourish and moisturize your hair to ensure you have beautiful and strong hair.

Increases Volume

This Redken collection also improves the thickness of your hair by increasing the volume.

Dry, porous hair often results in reduced volume and less hair overall.

Using Extreme shampoos daily, you can add texture to your fantastic hair.

Doesn’t Contain Parabens

The best part about Redken’s collection of Extreme Shampoos is that no product from this line contains any paraben. 

According to a source, parabens can be highly toxic to your hair and carry several risks.

They should be avoided at all costs, and Redken offered us the perfect solution.

Side Effects of Using Redken Shampoos

The only concern I have with this shampoo is that it contains multiple sulfates. It can be highly problematic for consumers with sensitive skin. 

Sulfate products can induce many side effects, such as irritation, dry hair, or redness on the skin. 

These side effects can be mild or intense. Certain hair products can cause an allergic reaction in some individuals.

Hence, it is recommended to consult a trichologist before using the Redken Extreme Shampoos.
