Olaplex Products Explained

You’ve probably noticed that each Olaplex product comes with its own number, from No.0 to No.9. While Olaplex No.1 & No.2 are for salon-use only, all other numbers from the Olaplex range can be used at home - yay! 😊

Here's our complete rundown of these Olaplex product numbers - explaining what each does, how to use each and which is best for different types of hair... 

Olaplex No.0 - Intense Bond Building Hair Treatment

Best For Heat or Colour Damaged Hair

Olaplex No.0 is the perfect hair treatment if your locks are feeling a bit frazzled. It works as a primer, prepping your hair for deeper repair when paired with other Olaplex products. The formula is light and almost water-like, it smells great and comes in an easy-to-use spray bottle. It’s a popular choice for anyone trying to restore their hair after heat styling or colouring.

How to Use Olaplex No.0:

1. Twist open the bottle and spritz the product on dry hair, applying from root to tip.
2. Leave it for 10 minutes (or up to 45 if you’ve got time – but don’t leave it overnight).
3. Apply Olaplex No.3 on top without rinsing, then leave both in for another 10-30 mins.
4. Rinse, then shampoo and condition as usual. Use weekly or 2-3 times a week for very damaged hair.

Olaplex No.3 - Hair Perfector

Best For Bleached Hair

Olaplex No.3 Hair Perfector is a cult-favourite for a reason - it’s one of the best products for repairing bleach damaged hair at home. It works by rebuilding broken bonds and reversing the damage caused by the harsh chemicals in bleach. The more you use Olaplex No.3, the healthier your processed blonde hair will become. No.3 is packed with the same patented ingredients as the in-salon treatments, so it’s perfect for keeping your hair in top condition between visits.

How to Use Olaplex No.3:

1. Apply a generous amount to damp, towel-dried hair, working from root to tip.
2. Leave it in for at least 10 minutes, although the longer the better (we always sleep with it overnight).
3. Rinse out thoroughly, then shampoo and condition as usual.
4. Use weekly, or 2-3 times a week for heavily damaged hair. One bottle should last several weeks depending on how often you use it.

Olaplex No.4C - Bond Maintenance Clarifying Shampoo

Best For Hard Water Areas & Swimmers

Olaplex No.4C is your go-to clarifying shampoo for removing product build-up, excess oils and impurities — all while protecting your hair's natural moisture. Unlike the original Olaplex No.4 shampoo, Olaplex No.4C shampoo offers a much deeper clean using ingredients like phytic acid. It’s ideal for all hair types, including curly hair, textured 4C hair and coloured hair.

How to Use Olaplex No.4C:

1. Apply a small amount to wet hair, massaging into the scalp.
2. Lather and work through the lengths of your hair.
3. Rinse thoroughly, then follow up with Olaplex No.5 Conditioner.
4. Use once a week for deep cleansing (there’s no need to use No.4 every day, as it’s designed for occasional use).

Olaplex No.4D - Dry Shampoo

Best For Fine Hair & Oily Hair

Olaplex No. 4D Dry Shampoo is a must-have for mid week hair, when you don't have time for a full wash and blow-dry! Unlike some other dry shampoos, No. 4D doesn’t just refresh your hair between washes; it also helps maintain your hair’s strength thanks to Olaplex’s bond-building technology. Unlike some high-street brand dry shampoos, this benzene-free formula is safe for everyday use, with key ingredients like Rambutan Seed Extract helping cleanse the scalp naturally.

How to Use Olaplex No. 4D:

1. Shake the can well before use.
2. Hold the bottle 6-10 inches from your roots and spray evenly on dry hair.
3. Let it sit for 30 seconds to absorb oil and impurities, then massage or brush through.
4. Use as needed between washes—it's gentle enough to be used daily if required.

Olaplex No 4P - Blonde Enhancer Toning Shampoo

Best For Brassy, Warm-Toned Hair

Olaplex No. 4P Blonde Enhancer Toning Shampoo (also known as Olaplex purple shampoo) is perfect for anyone looking to keep brassiness at bay. Although the name suggests this shampoo is just for blondes or lightened hair, it's actually suitable for all hair colours! Its violet pigments work to neutralise yellow tones, helping bring out cooler tones in grey hair, brunettes and even redheads. The Olaplex bond-building formula also strengthens hair, making it an excellent choice for those wanting to brighten their colour without damage.

How to Use Olaplex No.4P:

1. Apply to wet hair, massaging it into a lather.
2. Leave it in for 1-3 minutes for daily toning, or up to 5 minutes for more intense brassiness control.
3. Rinse thoroughly, and follow with conditioner or Olaplex No.5.
4. Use 1-2 times a week, depending on how much toning you need.

Olaplex No.5P - Blonde Enhancer Toning Conditioner

Best For Dry & Brassy, Warm-Toned Hair

Olaplex No.5P Blonde Enhancer Toning Conditioner (also known as Olaplex purple conditioner) is also designed to all colours of hair cool-toned and brass-free. Similar to the No.4P conditioner, this sulphate-free and paraben-free formula works by using violet pigments to neutralise yellow tones while also strengthening your hair. For the best toning results, it’s recommended to use No.5P with Olaplex No.4P, but it’s still effective on its own!

How to Use Olaplex No.5P:

1. Start by shampooing your hair (ideally with Olaplex No. 4P for best results)
2. Then rinse and apply No. 5P to damp hair, focusing on the mid to end lengths.
3. Leave it in for 3-5 minutes to allow the violet pigments to work their magic.
4. Rinse thoroughly. Use 1-2 times per week, or as needed for toning.

Olaplex No.4 & No.5 - Bond Maintenance Shampoo & Conditioner

Best For Day-to-Day Hair Washing

Olaplex No.4 Shampoo & No.5 Conditioner are the perfect daily-use duo for all hair types. If you're looking for a salon-quality shampoo and conditioner to keep your hair healthy at home, these are the set for you. Most people try the standard 250ml bottles to start with - these last surprising long as a little goes a long way.

However if you really want to invest in haircare, we recommend going for the 1000ml Olaplex Shampoo and 1000ml Olaplex Conditioner. On average, these can last up to one year when used on every wash day! Plus, you can save money when buying in bulk💲

How to Use Olaplex No. 4 & 5:

1. Apply a small amount of No. 4 shampoo to wet hair, massaging it into the scalp.
2. Rinse thoroughly, making sure to remove all shampoo from your hair.
3. Follow with No. 5 conditioner, focusing on the mid-lengths to ends of your hair.
4. Leave the conditioner on for at least 3 minutes, then rinse thoroughly. Use 2-3 times a week for best results.

Olaplex No.6 - Bond Smoother

Best For Naturally Frizzy or Damaged Hair

Olaplex No.6 Bond Smoother is a leave-in styling treatment that repairs, strengthens and protects all hair types. It smooths frizz, hydrates, and speeds up blow-dry time while strengthening hair with Olaplex’s bond-building technology. It doesn’t contain protein, however it’s packed with "Bis-Aminopropyl Diglycol Dimaleate" which also helps repair and protect hair bonds. While it’s not marketed as a heat protectant, it does offer some heat protection benefits, making it a great prep product before styling. In our opinion, No. 6 lives up to the hype, especially for those looking to manage frizz.

How to Use Olaplex No.6 Bond Smoother:

1. Start with damp or dry hair (it can be applied to both).
2. Dispense a pea-sized amount (a little goes a long way!) and rub it between your hands.
3. Work it through the mid-lengths to ends of your hair, avoiding the roots.
4. Style as usual—whether you air-dry or blow-dry, No. 6 will help smooth and strengthen your hair.

Olaplex No.7 - Bonding Oil

Best For Fans of Sleek, Shiny Hair & Heat Tools!

Olaplex No. 7 Bonding Oil is a lightweight, reparative hair oil designed to add shine and reduce frizz, all without weighing your hair down. If you’re wondering whether No. 7 doubles as a heat protectant — yes, it does! It helps strengthen your hair while providing heat protection up to 232°C (450°F). We think it’s one of the best hair oils out there, particularly for those looking for a multi-purpose product that smooths and protects.

How to Use Olaplex No. 7 Bonding Oil:

1. Apply Olaplex bonding oil to dry or damp hair (it works well on both).
2. Dispense 2-3 drops into your palm and rub between your hands.
3. Apply evenly through the mid-lengths to ends of your hair, avoiding the roots.
4. Style as usual, or use before heat styling for added protection.

This mask can be used on its own or after Olaplex No. 0 and No. 3 for an extra boost of repair and hydration.

2. Dispense 1-2 pumps and work through the mid-lengths to ends, avoiding the roots.
3. Leave the mask in for 10 minutes for deep hydration.
