Olaplex uses bond-building technology to repair hair from the inside out. It works by fixing broken disulfide bonds in your hair cuticle, which is where real damage happens.
The product line ranges from No.0 to No.9, so you can build a complete routine at home. Each formula is sulfate-free and heat-protective up to 450°F, making it safe for styled and treated hair.
You only need a dime-size amount per application because the concentrate is potent. Results build gradually over weeks of consistent use, but you get lasting structural strength rather than just surface shine.
Olaplex works best for chemically treated or severely damaged hair where you want real restoration. It’s ideal if you’re willing to commit to regular use for long-term bond repair.
Pros
- Repairs broken disulfide bonds at the molecular level
- Concentrated formula means a little goes a long way
- Restores natural lipids and strengthens hair gradually
- Works well on bleached, colored, and chemically treated hair
Cons
- Heavy texture; not ideal if you prefer lightweight products
- Requires consistent use to see noticeable results
- Doesn’t provide immediate moisturizing benefits like some alternatives
Redken Review
Last update on 2026-09-08 / Affiliate links / Images from Amazon Product Advertising API
Redken is a salon-grade professional line that delivers immediate results for damaged and color-treated hair. It uses a Bonding Care Complex with citric acid to seal the hair cuticle and restore smoothness fast.
The formula maintains an ideal pH balance between 4.5 and 5.5, which keeps your hair’s protective layer intact. This pH-balancing approach works differently than bond-building—it focuses on cosmetic improvement rather than deep structural repair.
Redken offers multiple ranges like All Soft and Extreme, each with targeted ingredients. All Soft uses birch sap for hydration, while Extreme contains lupine protein for extra strength on heavily damaged strands.
In real-world use, you notice softer, more manageable hair within one or two applications. The product removes buildup effectively, making it popular in professional salons and for people who want quick transformation.
Pros
- Instant softness and smoothness after first use
- Removes product buildup and residue from hair
- Works especially well on color-treated hair
- Salon-professional performance you can use at home
Cons
- Can leave a waxy or greasy residue on some hair types
- Ends may feel dry despite overall smoothness
- Buildup potential if used too frequently without clarifying
Head to Head: Key Differences
Olaplex and Redken take opposite approaches to hair repair. Olaplex fixes damage at the molecular level, while Redken delivers surface-level cosmetic improvements.
The core difference lies in how each brand works. Olaplex penetrates deep into your hair shaft and rebuilds broken disulfide bonds that form your hair’s internal structure.
Redken seals the hair cuticle and balances pH to create immediate smoothness and shine.
Olaplex requires patience and consistency. You won’t see dramatic changes after one wash because the formula works gradually to restore your hair’s foundation.
Most users notice real strength and elasticity after two to three weeks of regular use.
Redken gives you instant gratification. Your hair feels noticeably softer and smoother within one or two applications, making it perfect if you need quick results for an event or photo shoot.
The texture experience differs significantly between brands. Olaplex has a concentrated, heavier feel that some people find too rich for fine or thin hair types.
Redken feels lighter and more manageable, though some users report waxy residue or dryness at the ends with certain formulations.
Application amounts matter too. Olaplex requires only a dime-size amount per use because the formula is highly concentrated.
Redken typically needs a more generous application to deliver its pH balancing benefits across your entire hair length.
Choose Olaplex if your hair is severely bleached or chemically damaged and you want real structural restoration. Pick Redken if you prioritize immediate manageability and color protection for salon-quality results at home.
Your hair type and timeline determine which brand serves you better.
Which One Should You Buy
Olaplex takes the win in this match-up. It works deep inside the hair shaft to rebuild broken disulfide bonds.
This fixes damage at its source instead of just masking it.
Redken still shines for quick fixes. It smooths the cuticle and adds instant softness, especially after color treatments.
But for true, lasting repair, Olaplex is the smarter pick. It offers real structural change, not just a temporary glow.
Best for each buyer
- Olaplex: Best for people with chemically treated or damaged hair who want long-term bond repair and lasting strength.
- Redken: Best for people who want instant softness, easy manageability, and salon-fresh shine, especially for color-treated hair.
Frequently Asked Questions

Does Olaplex work better for chemically damaged hair?
Yes. Olaplex specifically targets broken bonds caused by bleaching, coloring, or chemical treatments.
Its bond-building technology actually fixes the damage at the source rather than just coating the surface.
Redken also helps color-treated hair by maintaining pH balance and removing buildup. However, it focuses more on immediate smoothness than deep structural repair.
If your hair has extensive chemical damage, Olaplex is the stronger choice. Redken is better for maintaining color-treated hair between treatments.
Can I use just a tiny amount of each product?
Olaplex yes. A dime-size amount covers most hair lengths because the formula is highly concentrated.
This makes each bottle last longer.
Redken typically needs more product to deliver its pH-balancing benefits across your entire hair. A generous application ensures even coverage.
Which product leaves less residue?
Redken sometimes leaves a waxy or greasy feeling, especially with certain formulations. Some users also report dryness at the ends.
Olaplex is heavy but doesn’t typically leave buildup. It absorbs into the hair structure rather than sitting on the surface.
Should I choose one or use both?
Many people use both. Apply Olaplex first for deep repair, then use Redken for immediate shine and manageability.
This combination gives you structural healing plus instant results.
