Olaplex No.3 vs No.0: What's the Difference and How to Use Them
Share
Quick answer: Olaplex No.3 Hair Perfector is a weekly at-home bond repair treatment you apply to damp hair for at least 10 minutes before shampoo. Olaplex No.0 Intensive Bond Building Treatment is a spray primer you use before No.3 to make it work harder. For a full treatment: spray No.0 on dry hair, wait 10 minutes, apply No.3 on top without rinsing, wait at least 10 more minutes, then shampoo and condition.
Olaplex No.3 is one of those products everyone has heard of. Then you find out there's a No.0 too, and the instructions on the bottles start to feel like a puzzle. Let's clear it up.
How Olaplex works (in plain words)
Hair strength comes from bonds inside each strand. Bleach, colour, heat styling and even UAE sun and hard water break some of those bonds, which shows up as frizz, breakage, split ends and that straw feeling. Olaplex's patented ingredient, bis-aminopropyl diglycol dimaleate, is designed to relink broken bonds from the inside. It doesn't just coat the hair like a regular conditioner.
Olaplex No.3 Hair Perfector
- What it is: a creamy pre-shampoo treatment
- Who it's for: damaged, coloured, bleached or heat-styled hair, and anyone wanting stronger hair
- How often: once a week. Up to two or three times a week for very damaged hair.
How to use No.3:
- Wet your hair and towel dry so it's damp, not dripping.
- Apply No.3 from roots to ends, focusing on the most damaged parts. Comb through.
- Leave for at least 10 minutes. Longer is fine, many people leave it 30 to 45 minutes.
- Rinse, then shampoo and condition as usual.
Olaplex No.0 Intensive Bond Building Treatment
- What it is: a lightweight liquid spray, a primer for No.3
- Who it's for: very damaged or bleached hair that needs more than No.3 alone
- How to use: it's never used alone, always followed by No.3 (see the routine below)
- How often: once a week, or when you want a deeper treatment

The full No.0 + No.3 routine
- Start with dry, unwashed hair.
- Spray No.0 all over until your hair is saturated. Work it through with your fingers.
- Leave it for 10 minutes.
- Don't rinse. Apply No.3 straight on top, from roots to ends.
- Leave No.3 for at least 10 minutes (longer for more damage).
- Rinse, then shampoo and condition. Olaplex No.4 Shampoo and No.5 Conditioner are designed to follow, but your usual shampoo works too.
Don't have No.0? No.3 on its own still does the main repair work. No.0 is a booster, not a requirement.
Common mistakes
- Putting No.3 on soaking wet hair. It dilutes it. Towel dry first.
- Using it as a conditioner after shampoo. No.3 is a pre-shampoo step.
- Rinsing No.0 before No.3. The two are meant to work together on the hair.
- Expecting one use to fix bleach damage. Most people notice softness after the first use, but real strength builds over several weeks.
Tips for UAE hair
Hard water leaves minerals on hair that make it feel rough and can dull colour. Sun and chlorine from pools add to the damage. If your hair is coloured, a weekly Olaplex No.3 plus a heat protectant before blow drying makes a visible difference within a month. For frizz between washes, No.6 Bond Smoother or No.7 Bonding Oil help.
