The wash-day edit
Olaplex vs. Redken Conditioners: Which Fits Your Hair?
Choose by your hair's needs, with four rinse-out options for fine texture, conditioning, dryness and damage-focused care.
Comparing Olaplex vs. Redken conditioners? Start with the formula rather than choosing a whole brand. If fine hair makes lightweight conditioning your priority, consider Olaplex No.5 FINE Bond Maintenance Conditioner. For dry, brittle lengths, look at Redken All Soft Conditioner. Olaplex No.5 Bond Maintenance Conditioner offers concentrated conditioning and detangling, while Redken Acidic Bonding Concentrate Conditioner is positioned for damaged hair.
All four occupy the same wash-day step: conditioner after shampoo, followed by rinsing. The useful question is which one addresses your main concern without making your routine harder to manage. You do not need all four.
Which conditioner matches your main priority?
Use this shortlist to narrow the choice. These are starting points based on the products' stated roles, rather than results from a head-to-head test.
| Your priority | Consider | Useful distinction |
|---|---|---|
| Fine hair; a lightweight feel | Olaplex No.5 FINE Bond Maintenance Conditioner | A formula specifically positioned for fine hair. |
| Concentrated conditioning and detangling | Olaplex No.5 Bond Maintenance Conditioner | The regular formula in this pair. |
| Damage-focused conditioning | Redken Acidic Bonding Concentrate Conditioner | A damaged-hair focus within the range. |
| Dryness and softness | Redken All Soft Conditioner | Argan-oil conditioning for dry, brittle hair. |
Four formulas, four starting points
For concentrated conditioning
Olaplex No.5 Bond Maintenance Conditioner
Consider this option when hydration and easier detangling are your main aims. The manufacturer describes a concentrated conditioner, so the product's directions and your hair's response matter more than a generous-looking handful.
The regular formula is a separate choice from the fine-hair version below. A shared number on the bottle does not make the two interchangeable. Selected format: 250ml.
See the manufacturer's product guidance.
For fine texture
Olaplex No.5 FINE Bond Maintenance Conditioner
If conditioner choice often comes down to keeping fine hair feeling light, start here. This formula is specifically positioned for lightweight conditioning of fine hair, making that priority easier to shop for.
Fine texture and dryness can overlap. Choose according to the concern you most want your conditioner to address, then assess the feel after rinsing and drying. Selected format: 250ml.
See the manufacturer's fine-hair guide.
For a damage-focused routine
Redken Acidic Bonding Concentrate Conditioner
This is the damage-focused option in the comparison. Consider it if that positioning matches the reason you are reassessing your conditioner, rather than selecting purely for softness.
A product's bonding language does not establish that it outperforms another brand. Compare the actual conditioner and its directions; neither a technology name nor the front label can tell you exactly how your hair will feel. Selected format: 300ml.
See the manufacturer's product guidance.
For dry, brittle lengths
Redken All Soft Conditioner
Choose this as a starting point when softness and moisture are the main goals. Its argan-oil formula is positioned for dry, brittle hair, giving it a different emphasis from the damage-focused option above.
That distinction helps you shop; it is not a rule excluding every other hair type. Use the stated role to narrow your choice, then judge whether the conditioning feel works for you. Selected format: 300ml.
See the manufacturer's product guidance.
How do you use them on wash day?
Shampoo first, then follow the directions for the conditioner you choose:
- Olaplex No.5 Bond Maintenance Conditioner: apply through mid-lengths and ends, leave for 1–3 minutes, then rinse.
- Olaplex No.5 FINE Bond Maintenance Conditioner: apply to mid-lengths and ends, leave for 1–3 minutes, then rinse, following the official fine-hair guide.
- Redken Acidic Bonding Concentrate Conditioner and Redken All Soft Conditioner: apply after shampoo, distribute through the hair and rinse thoroughly. Their official instructions do not specify the same timed pause as the two options above.
Check the directions on the bottle you receive. Avoid turning a rinse-out step into an overnight treatment or assuming longer contact means better results.
Questions before you choose
Is No.5 FINE the same as regular No.5?
No. They are distinct conditioners, with the fine-hair formula emphasizing lightweight conditioning. Choose between their intended roles rather than treating the added word as a packaging difference.
Can these replace a leave-in conditioner?
These four formulas are designed to be rinsed out. A leave-in is a separate product with its own directions. Do not assume this rinse-out step provides heat protection for styling.
Do you still need conditioner on mask day?
Check your exact mask's instructions before adding another step. Our guide to whether to use conditioner after a hair mask explains how to approach that decision.
A simple way to make the choice
Pick one main priority, choose the corresponding starting point and use it as directed. Notice detangling, softness and how your hair feels once dry. That gives you a more practical basis for your next purchase than trying to name one winning brand for everyone.
