Olaplex 8 hydrates, softens and smooths your hair while the Bond Building technology helps strengthen damaged hair bonds. Use it as a rinse-out mask after washing, especially if your hair feels dry, fragile, frizzy or dull.

The formula is concentrated, so you don’t need a lot. According to product info, the mask provides:

• twice as much shine
• four times more hydration
• six times more smoothness
• noticeably more body
• a softer, fuller hair feel

That’s why Olaplex No.8 doesn’t feel like a standard conditioner. It’s more like a weekly care boost for hair that needs a bit more than just washing and conditioning.

Olaplex No.8 suits all hair types but is especially good for dry, damaged, coloured, bleached, frizzy or lifeless hair. Curls can also benefit from the extra hydration and smoothness, especially if your hair feels stiff quickly.

Choose this mask if your hair:

• feels dry quickly after washing
• shines less than usual
• is frizzy or rough on the lengths
• is often coloured or bleached
• regularly exposed to heat from blow dryers, straighteners or curling irons
• needs care but shouldn’t feel heavy

If you have very fine hair, start with a small amount and mainly apply to the lengths and ends. This way, you care for your hair without the roots feeling heavy faster.

Olaplex’s Bond Building technology targets disulphide bonds in hair. These bonds give your hair structure, strength and stability. Colouring, bleaching, heat and brushing can damage them. Olaplex uses Bis-Aminopropyl Diglycol Dimaleate, the brand’s well-known patented ingredient.

In Olaplex No.8, this repair technology combines with a hydrating mask. So it’s not just a treatment for hair bonds, but also a nourishing step for softness, shine and body.

Good to know: No.3 focuses mainly on repair before washing. No.8 is used after washing as a mask. They complement each other but have different places in your routine.

Olaplex 8 fits best in your routine after washing. For example, wash your hair with Olaplex No.4, towel-dry it and apply No.8 to the lengths and ends. Leave on for 10 minutes then rinse thoroughly.

Want a more intensive repair routine? Use Olaplex No.3 Plus before washing first. Then wash your hair and finish with No.8 for extra hydration and shine. Olaplex confirms No.0, No.3 and No.8 can be used together in the same treatment cycle.

A simple routine looks like this:

1. No.3 as a pre-wash treatment if you want extra repair.
2. No.4 shampoo to wash your hair.
3. Olaplex 8 as a mask on towel-dry hair.
4. No.6 or No.7 as a styling step to combat frizz, add shine or provide heat protection.

Use No.8 once a week or whenever your hair feels dry and dull. For very damaged hair, you can use it a bit more often as long as your hair stays light and flexible.

What’s the difference between Olaplex No.3 and No.8

Olaplex No.3 is a pre-wash treatment you use before shampooing to repair damaged hair bonds. Olaplex No.8 is a rinse-out hair mask used after washing for hydration, shine, smoothness and body. No.3 is the repair step, No.8 is more the nourishing mask boost.

How often should I use Olaplex No.8?

Use Olaplex No.8 once a week. That’s enough for most hair types to add extra hydration, shine and softness. If your hair feels very dry or damaged, you can use it more often. Pay attention to how your hair reacts.

How much product do I need per use?

Start with one pump. For short or fine hair, less is often enough. For long, thick or lots of hair, use a little more. Apply mainly to the lengths and ends to prevent the roots feeling heavy while the dry parts get enough care.

Is Olaplex No.8 suitable for coloured hair?

Yes, Olaplex No.8 works well with coloured or bleached hair. Chemically treated hair can feel dry, dull or fragile. This mask helps add hydration, smoothness and shine to your routine without needing an extra styling step.

Can I combine Olaplex No.8 with other products from the range?

Yes, Olaplex No.8 combines well with other products in the range. If you’re looking to build a complete routine, use No.3 before washing, No.4 shampoo and No.8 as a mask. Then style with No.6 or No.7.

With Olaplex No.8, you give your hair a moment to truly repair and recharge. Especially if your hair gets dry, frizzy or dull quickly, this mask immediately makes your routine more logical. No fuss, just wash, leave in and enjoy softer hair with Olaplex 8.
