You may not know this, but every product and treatment you apply to your hair breaks precious disulfide bonds within its follicles. Obviously, bleaches, dyes, and heat treatments aren’t great for your hair, but shampoos, conditioners, and hair masks can also damage the bonds in your hair over time, leaving it dryer and more brittle.

Even the sun, seawater, and chlorinated water from swimming pools can damage your hair! Olaplex products are specifically designed to repair your hair’s broken bonds at a molecular level, restoring it to its original strength, healthiness, and shine.

This is the ultimate guide on  How to Use Olaplex No. 3 at Home. I will answer some important questions about the Olaplex No. 3 Like can you leave it overnight? How long does it last? and how frequently should you use it?

Celebrities like Kim Kardashian, Jennifer Lopez, and Drew Barrymore swear by Olaplex No. 3 to protect and strengthen their hair through numerous dye jobs, styling treatments, and heat processes.

Finally, consumers themselves have given rave reviews to Olaplex No. 3. Many people credit this miracle product for saving their hair after bleaching gone wrong, extreme color changes, and years of damage due to heat styling, perms, and chemical straightening.

No matter how damaged your hair is, Olaplex No. 3 can save it!

What is Olaplex?

Olaplex is beloved by professional hairstylists and salons all over the world for its unbelievably effective step-by-step hair care program.

The space-age science behind it almost sounds like it comes from a movie: Olaplex products rebuild broken disulfide bonds within the molecular structure of your hair, reversing the damaging effects of heated styling tools and harsh chemical treatments.

If your hair is dry, dull, damaged, frizzy, or breaks easily, you can trust Olaplex to heal your follicles and restore them to their happiest, healthiest selves!

The first three steps in Olaplex’s patented hair treatment system are not the same as shampoos and conditioners. Instead, they’re meant to supplement your pre-existing haircare regimen, ensuring that your hair is as healthy as possible.

Olaplex No. 1 and Olaplex No. 2 are meant to be used as part of the hair coloring process to prevent your hair from damage.

Olaplex No. 3 is an at-home version of Olaplex’s bond multiplying technology, so you can see continued great results long after your hair has been dyed!

What is Olaplex No. 1 and 2?

Olaplex No. 1 is a bond multiplier. It begins to rebuild all of the broken disulfide bonds within your hair, repairing existing damage and helping to prevent future damage. It’s supposed to be mixed into bleach or hair dye to help protect your hair from the damaging effects of harsh chemicals.

Olaplex No. 2 is a bond perfector. It works to rebuild any of the broken bonds that Olaplex No. 1 missed, leaving your hair stronger, softer, and shinier. It’s meant to be applied right after you finish bleaching or coloring your hair.

Olaplex No. 1 gets mixed into your bleach or hair dye. The amount of Olaplex No. 1 you should mix in depends on your hair length and whether you’re using bleach or dye.

Carefully follow the instructions included with Olaplex No. 1 so that you know the exact proportions you should be using for your hair! After you rinse the bleach or dye out of your hair, you’ll find that Olaplex No. 1 has protected it from harsh chemical damage, leaving it much softer, smoother, and shinier than usual!

Next, after you’ve finished dyeing or bleaching your hair and have rinsed it all out, apply Olaplex No. 2!

Apply a generous amount from root to tip and leave it on for at least 20 minutes, so that the formula has enough time to repair all of the broken molecular bonds that Olaplex No. 1 wasn’t able to catch.

After at least 20 minutes, hop in the shower and use your regular shampoo and conditioner to rinse Olaplex No. 2 out. You’ll notice that your hair is super silky, smooth, and feels hydrated and soft to the touch!

    • Yes! You’re actually suppose to put O-3 into the bleaching mixture.. You use O-1 & O-2 Prior tp bleaching or harsh treatments on your hair, O-3 you put into the bleaching mix, Then O-4 & O-5 are after treatments and care.
      Hope this helps.

      • No, DoneGoneBlonde, that’s not right at all.
        -O1 & O2 are for salon use only, only sold to licensed hairstylists. It is ONLY sold by the real manufacturer to licensed individuals and salons. O1 goes into the bleach mixture, O2 Is applied directly, after for 20 minutes. Because O1 can’t work without following up with O2, they MUST be used together.
        -O3 is the stand-alone treatment sold to general public, it does not get mixed into bleach.
        -Then O4 is their shampoo and O5 is their conditioner.

  1. Last night i kept o#3 (with my silk hair bonnet) in my hair overnight. This morning I washed my hair with my usual shampoo and then conditioned with o#5. My hair is softer, and I’m wondering if I can skip the shampoo and just rinse out with the o#5? Is shampoo really necessary to get out the o#3? My hair is on the dry side, so shampooing 2 days in row, for this process dried the heck out of my hair. But because it says to apply o#3 on towel dried hair, I wanted to make sure that my hair was super clean and whatnot maybe so it could work better. But then to wash again with shampoo 12 hours later made me reconsider this because although my hair is softer, it’s actually super dry. Not sure what to do. I don’t mind shampooing before hand, but I’m wondering about the efficacy of shampooing it out versus washing it out with the o#5. As for some background, I normally shampoo once a week or once every 2 weeks, but I condition everyday or every other day because my hair is dry/processed.

    • Hey Parro! Don’t wash your hair with shampoo before you apply it 🙂 just dampen it and then apply. Don’t worry about your hair being super clean, it’s just better this way. I also have very dry hair usually. I personally only wash my hair once a week. I use olaplex 0 (You can just use water if you don’t have this or plan to purchase it) to moisten my hair and then apply 3! I personally don’t use shampoo afterwords, or at all, unless I have a product build up. But it is still important to gently scrub your scalp even if you just use conditioner! Hope that helps in some way 🙂

  2. Brilliant synopsis of Olaplex. Informative and interesting to read. I only use No.3 as I care for my hair at home. Just finished my first bottle, half a bottle used each wash day. I love it and my hair loves it too. My hair feels stronger and looks very healthy.
    Thank you xx

  3. Immediately after dyeing my hair at home, is it OK to use No.3, 4 and 5 rather than immediately using the conditioner that came with the dye?

  4. Can you use O3 in your hair immediately after dying it? Like, rinse out the dye, O3, rinse out an hour later, shampoo, then conditioner.

    • You do not add #0 and/OR #3 to bleach. Use them AFTER bleaching. You’d want to use #0 on dry hair leave in for 10-20 minutes then add #3 and leave for as long as it’s still moist, and shampoo out and condition. If you had #1 and #2 the instructions would tell you how much #1 to add to bleach and #2 is used after removing bleach.

  5. Thank you so much for all the advices !

    I went from black to platine blond.
    I started the process at home on half my hair (front) and I achieved a light blond but my hair were drier than usual. Then I decided to change more of my hair and harmonize the whole, so I went to the hair salon… I never go and the one I went just didn’t took care of me, leaving me with the foil paper on my hair for almost 3 hours, taking care of regular customers… I ended up with the worst damaged hair, an en even color (because they didn’t separate my already bleached hair from the dark ones) and made a terrible mess (I have now a little Mohawk along my middle part and a baby bang). As you can imagine : I was crying like a baby. Especially as the hairdresser started to point me as guilty, didn’t apologize and made me pay full price.
    SO I decided to go full blond, and rock a baby bang !
    I bleach my hair at home, separating all the different layer of bleached and not bleached hair, then did a “patine”, then shampoo, combed, towel-dried my hair.
    I’m not going to put olaplex n0, leave 20 min, then add n3 and leave over night.

    I’ll come back tomorrow for the result !
