Can You Sleep With Olaplex 3 in Your Hair? YES, But There Are A Few Things to Consider

Olaplex is a solution that’s used to restore and maintain the health of chemically processed hair. It’s not shampoo, but it can be applied to clean, wet hair before you shampoo and condition it. Olaplex restores the structure of your hair by bonding broken disulfide bonds in your hair with its own active ingredient, 1,4-diamino-2-piridinopropane (DAP).

You might have heard that you should never sleep with Olaplex in your hair. But while there are some restrictions on how often you can use Olaplex, it’s still possible to sleep with Olaplex 3 in your hair. Here, are some things you should know a

What is Olaplex?

The Japanese drug company Shiseido’s Olaplex brand has been selling hair product for several years now. Initially, it was used to revitalize strands by chemically repairing (disulfide bond) that had gone awry.

More recently, the brand has introduced three different products, Olaplex (the original version), and then, in 2015, Olaplex 3 and 4. Olaplex 3 and 4 are applied to wet hair before you shampoo and condition. It uses the principle of bonding, which is quite similar to the ones used by nail polishes like OPI Hard As Nails and Zoya Nail Lacquer.

Just like the base color in OPI Hard As Nails, Olaplex 3 and 4 contain different base components (glycolic acid and formaldehyde bonds) that are thought to weaken or bond one type of disulfide to the base color and give it a similar effect.

Can you sleep with Olaplex in your hair?

Although there’s no absolute rule, if you’ve got oily hair, it’s unlikely that you’ll be able to sleep with it in your hair. However, if your hair is naturally oily, it’s a completely different story. If you’re prone to oiliness, then give it a go.

Is Olaplex the same as sulphate-free shampoo? This is a bit of a mixed bag. If you’re shampooing more frequently than two or three times per week (more than your average skincare routine), you should get rid of any sulphate products from your routine (and your hair).

If you’ve got very oily hair that’s pretty chemically processed, you should definitely stay away from sulphate-free shampoos. So check your labels.

How often can I use Olaplex?

You are able to use Olaplex for three weeks at a time, from wash to wash. The downside is that you can only use two of the available, trademarked Olaplex treatments. And if you run out of both the active ingredients, you’re stuck washing your hair with shampoo for a few weeks.

After that, you can still use Olaplex to repair your hair, but your hair will have to be left completely natural. You can always order a fresh treatment if you run out, but for the sake of consistency, it’s better to keep your hair clean and dry.

How long can I sleep with Olaplex 3 in my hair? Three weeks is the only time period that you can use Olaplex, although you could theoretically sleep with it longer.

What are the benefits of using Olaplex?

You don’t have to choose between cleaning up the products on your face or cleaning your hair. With Olaplex, you can put your hair through the proper shampoos and conditioners to clean and maintain your hair structure without having to replace all of the products you already use.

This helps protect your hair from harsh chemicals like formaldehyde and formic acid, both of which can be found in shampoo and conditioners. What are the benefits of sleeping with it? By maintaining your hair’s structure, you can leave your hair salon for the first time and go on vacation.

The first application of Olaplex makes your hair stronger and more flexible, making it resistant to heat styling, curling and straightening. Olaplex also repairs the broken bonds that cause hair to thin and fall out.


As you can see from the chart above, you can use both types of Oligonol treatments in the same hair. If you have dry hair or you’re a color patient and want to strengthen your color, use a full formula with Oligonol 1 and Oligonol 2.

If you have medium or wet hair and you need volume, use a partial formula with Oligonol 1 and Oligonol 2. For super curly or kinkier hair, Olaplex 3 might be a better choice.
