If your salon already adds Olaplex No.1 to lightener and colour, you know it makes a difference. But No.1 is only half the story. The step that finishes the job happens at the basin, and that's where Olaplex No.2 Bond Perfector comes in.
What is Olaplex No.2?
No.2 Bond Perfector is a professional-only treatment and the second step of the Olaplex in-salon system. It's applied at the backbar after the chemical service has been rinsed out. It isn't a conditioner, sealer or neutraliser. It carries the same bond-building active as No.1, and its job is to find and reconnect the broken disulfide bonds that No.1 couldn't fully protect while colour or lightener was working on the hair.
That's why Olaplex treats No.2 as essential rather than optional. No.1 reduces damage during processing, but no additive can stop all of it, or the colour wouldn't lift or deposit. No.2 mops up what's left, once the chemicals are no longer working against it.
Which size is right for your salon?
- No.2 Bond Perfector 100ml suits freelance and mobile stylists, smaller salons, or anyone trialling Olaplex services for the first time.
- No.2 Bond Perfector 525ml is the better-value choice for busy salons running regular colour and lightening services.
How to use No.2 after a colour or lightening service
- Rinse the colour or lightener out thoroughly. Don't shampoo yet.
- Towel-dry so the hair is damp, not dripping.
- Apply a generous amount of No.2 from roots to ends and comb through evenly.
- Leave on for a minimum of 10 minutes. On compromised or heavily lightened hair, longer processing gives better results.
- Rinse, then shampoo and condition. No.4 Bond Maintenance Shampoo and No.5 Bond Maintenance Conditioner keep the system consistent.
Always check the mixing chart and directions supplied with your bottle, as service ratios and timings can be updated by the brand.
The Olaplex Stand-Alone Treatment
No.2 isn't just for colour clients. Paired with No.1, it forms the Olaplex Stand-Alone Treatment, a great add-on for clients with dry, brittle or heat-damaged hair who aren't booked in for a chemical service. Dilute No.1 with water as directed, apply to the hair, then follow with No.2 without rinsing in between. It's an easy upsell that clients can feel straight away.
New to Olaplex? The Olaplex Salon Intro Kit (No.1 + No.2) gives you both professional steps together, so you can start offering bond-building services straight away.
More ways to get value from a backbar bottle
Many stylists keep No.2 within reach for much more than the end of a colour service:
- Mini treatment before a cut or blow-dry: a few minutes of No.2 on towel-dried hair is a simple way to introduce new clients to Olaplex.
- Cutting lotion: work a small amount through damp hair before cutting, then cleanse and style as usual.
- Protecting mid-lengths and ends: apply to previously lightened lengths while processing a regrowth to help prevent overlap damage.
- Diluting direct dyes: use in place of a clear gloss or conditioner to soften the shade while adding bond protection.
- Beard treatment: a quick way to soften coarse facial hair during a grooming service.
No.2 vs No.3: what's the difference?
Clients often ask whether No.2 and No.3 are the same thing. They're closely related but made for different settings:
- No.2 Bond Perfector is a professional product, designed to be used by trained stylists at the basin as part of a chemical service or salon treatment.
- No.3 Hair Perfector is the take-home version, created so clients can keep repairing between appointments. It's a weekly pre-shampoo treatment applied to damp hair before cleansing.
The best results come from using both: No.1 and No.2 in the chair, then No.3 at home to maintain the strength you've built.
Building a complete Olaplex routine for your clients
Recommending the right retail products after a service helps clients protect their colour and keeps them coming back. A simple home routine looks like this:
- No.3 Hair Perfector once a week before shampooing
- No.4 Bond Maintenance Shampoo and No.5 Bond Maintenance Conditioner for everyday cleansing
- No.4P Blonde Enhancer Toning Shampoo for blondes who need to keep brassiness in check
- No.0 Intensive Bond Building Treatment paired with No.3 for an extra-strength at-home boost
