Redken Extreme Strengthening Vs. Extreme Bleach Recovery Vs. Extreme Lengths, Which System Is Right For You?

As a beauty editor, I come across a lot of products. From shampoo and conditioner to mousse and gel, the rotation of hair products is almost never-ending, and after the 10th new shampoo of the month, all of the products can begin to blend together. That’s especially true for products that claim to do similar things. Why should I trust this breakage shampoo over that one? And how do I know which one is right for my mane?

I’m a huge fan of the original Redken Extreme Strengthening range, so I was ecstatic when Extreme Length and Extreme Bleach joined the family. But then I started to wonder, my hair loved Extreme Strength, but could it benefit more from Extreme Length? Or Extreme Bleach? If you, like I was, are wondering which Redken Extreme range is right for you and your hair, you’ve come to the right place. I’m breaking down everything you need to know about each line and revealing which range is right for what hair type.

If you’re dealing with damage and split ends, the Redken Extreme Strengthening range is perfect for you.

Redken Extreme Strengthening is the OG of the Extreme family and is has an almost cult-like following—for a good reason. The award-winning range, which consists of six products, promises to help fortify and strengthen damaged hair, helping to put an end to fragile strands and split ends. Formulated with Redken’s exclusive RCT Protein Complex, the system treats hair from the root to the core to the tip, giving all three levels the custom nourishment they need.

The best part about the Redken Extreme Strengthening Range is that even if you aren’t dealing with damage, you can still benefit from many of the products.

Having strong hair is always important, but it’s especially important if you’re trying to grow down-to-there-hair.

The best part about the range is that you can benefit from the products even if you’re not hoping to grow mermaid-length hair.

If you’re a salon blonde or receive a regular chemical service, the Redken Extreme Bleach Range is perfect for you.

Anything from too much brushing to extremely tight hairstyles can cause damage to your hair, but if you bleach your mane or get a regular chemical service, your hair likely needs some extra TLC. Redken Extreme Bleach is a reparative system for ultra-sensitive, damaged hair. When used as a complete system, the range restores strength, softness, shine, and healthy touch to hair in between lightening services.

All of the products are amazing, but we can’t get enough of Redken Extreme Bleach Lamellar Water. This rinse-out conditioning treatment instantly fills the porosity of the hair while providing softness, smoothness, and shine.
