If you’re into hair care, chances are you’ve heard of Olaplex. It’s practically a household name in the beauty world, loved by hairstylists, celebrities, and beauty enthusiasts alike. And with all the buzz around it, it’s easy to get swept up in the hype—but for a good reason! Olaplex is famous for its bond-building technology that repairs and strengthens damaged hair, taking it from dull and lifeless to strong, shiny, and resilient.
But here’s the thing: with a lineup of different products (and each one labeled by number, no less), it can feel a bit overwhelming to figure out where to start. Should you reach for Olaplex No. 3, the cult-favorite treatment? Or maybe the No. 7 Bonding Oil that promises shine and heat protection? Each Olaplex product has a unique formula and purpose, so picking the right one can feel like trying to crack a secret code!
That’s why we’re here to break it all down for you. In this guide, we’ll take a closer look at each product in the Olaplex lineup and help you answer the golden question: Olaplex, which one to buy? Whether you’re looking to repair intense damage, add shine and softness, or simply keep your hair healthy between salon visits, we’ve got you covered. By the end, you’ll have a clear idea of which Olaplex products best suit your hair type and goals.
So grab a cup of tea or coffee and let’s dive into the wonderful world of Olaplex. Trust us, your hair will thank you!
So, what makes Olaplex such a game-changer? It’s all about the science! At the core of every Olaplex product is this amazing, patented bond-building technology. Think of it as a little miracle worker that dives deep into your hair’s structure and repairs it from the inside out. Unlike other products that just coat the hair’s surface, Olaplex works at a molecular level. It specifically targets and repairs the disulfide bonds—the tiny connections within your hair that give it strength, elasticity, and shape.
Now, why is this important? Because these bonds are constantly getting broken by everyday things like heat styling, coloring, and even brushing. When they’re damaged, your hair becomes brittle, frizzy, and just plain tired-looking. That’s where Olaplex steps in, making it a lifesaver for anyone dealing with hair that needs a little tender loving care—or a lot! Whether you’ve got damage from frequent color treatments, regular blowouts, or just want to keep your hair in top-notch condition, Olaplex has something for everyone.
And the best part? You can get the benefits of an Olaplex treatment at home. No need to book an expensive salon appointment—each product is designed for easy, effective use right in your own bathroom. Let’s dive into the Olaplex lineup and figure out which one (or which combination) is perfect for you!
Think of Olaplex No. 0 as the primer that gets your hair ready for the ultimate repair. It’s a prep step that lays the foundation for other Olaplex products, especially the popular Olaplex No. 3, to work their magic even better. No. 0 is loaded with the same bond-building technology Olaplex is known for, which targets and repairs weakened hair bonds. This is a powerhouse product if your hair is showing signs of serious stress from color, bleach, or heat styling, giving you a way to get professional-level results at home. If you’re exploring Olaplex for home use and want to boost the impact of your treatments, No. 0 is a game-changer.
This one’s for those of us dealing with seriously compromised hair—think dryness, breakage, or that frazzled feeling from too much processing. If your hair needs more than a little TLC, or if you’re trying to level up your Olaplex treatment at home routine, No. 0 is the perfect partner for No. 3, helping you get the maximum repair benefits.
Applying No. 0 is super straightforward! Start with dry hair, then saturate it thoroughly with the product. Leave it on for about 10 minutes—enough time to let it soak in and get to work. After that, layer on Olaplex No. 3 and let them do their thing together. This dynamic duo is designed to transform your hair over time, making it stronger, shinier, and healthier with each use. It’s the perfect solution if you’re wondering Olaplex, which one to buy to get a serious at-home repair treatment.
This is the OG Olaplex product—the one that made everyone start talking about the magic of bond repair! No. 3 Hair Perfector is known for its ability to strengthen and repair damaged hair like no other. It’s packed with Olaplex’s patented bond-building technology, meaning it works to rebuild broken bonds in the hair, leaving it stronger, shinier, and smoother. This product is a real game-changer for anyone dealing with damage from bleaching, coloring, or excessive heat styling. And it’s super versatile! Whether you’ve got fine, straight strands or thick, curly coils, No. 3 will make your hair feel softer, healthier, and more resilient.
No. 3 is perfect for anyone who wants an Olaplex treatment at home without needing a salon appointment. If you’re dealing with dryness, breakage, or any signs of damage, this is the product for you. It’s particularly popular for those wanting to add Olaplex for home use into their weekly hair care routine. Whether you’re recovering from a color job, battling heat damage, or just looking to boost your hair’s health, No. 3 can work wonders.
For an at-home bond repair session, start by applying No. 0 (Olaplex’s intensive treatment primer), then follow up with No. 3. Make sure your hair is damp, apply No. 3 generously from roots to ends, and let it work its magic for 10–15 minutes. If your hair is especially damaged, you can leave it on for even longer to give it an extra boost. Rinse thoroughly, and prepare to be amazed at how much stronger and shinier your hair feels! Most people use it once a week, but if your hair is feeling particularly fragile or damaged, you can use it up to three times a week.
This is the go-to product for anyone wondering, “Olaplex which one to buy?”—it’s an accessible, effective way to bring professional-quality hair repair into your own bathroom.
Let’s be real—this isn’t your average shampoo. Olaplex No. 4 is designed to do more than just clean; it actually strengthens your hair as you wash. It’s sulfate-free, which is a big deal if you’re worried about stripping your hair of its natural oils. Plus, it’s packed with Olaplex’s signature bond-building technology, so with each wash, you’re repairing and reinforcing your hair’s structure. Think of it as giving your hair a mini Olaplex treatment at home every time you shower.
If you’re after a shampoo that’s gentle enough for daily use but still packs a punch in terms of benefits, No. 4 is definitely one to consider. It’s especially fantastic if you have color-treated or chemically-processed hair, which needs that extra TLC. Even if you’re just aiming to improve your hair health and want an easy way to add Olaplex for home use into your routine, this shampoo is a top choice.
Using No. 4 is super simple and effective. Just apply a small amount to wet hair, lather it up, and rinse thoroughly. For best results, follow up with Olaplex No. 5 Bond Maintenance Conditioner. Together, these products make for a complete Olaplex treatment at home that keeps your hair healthy, shiny, and resilient.
Olaplex No. 5 Bond Maintenance Conditioner is a lifesaver for anyone whose hair craves a serious boost of hydration and repair. This conditioner doesn’t just make your hair feel softer on the surface—it works deep down to actually strengthen each strand. With regular use, you’ll notice fewer tangles, less breakage, and a smoother texture that just feels healthier overall. It’s packed with moisture, but don’t worry about it leaving your hair feeling heavy or greasy. This formula is all about balance, giving you hydration without the weight.
If you’ve got dry or damaged hair, especially from frequent coloring, heat styling, or environmental exposure, No. 5 is a game-changer. It’s ideal for anyone who wants to boost their hair’s hydration without compromising volume or bounce. Plus, it’s safe for all hair types, so whether your hair is curly, straight, thick, or fine, this conditioner will work wonders.
Using No. 5 is simple and perfect for an Olaplex treatment at home. After washing with Olaplex No. 4 Bond Maintenance Shampoo, take a generous amount of No. 5 and apply it from the mid-lengths to the ends of your hair. Focus on the areas that feel the driest or are prone to damage. Let it sit for a few minutes—consider this your mini spa moment. While it’s working its magic, you can enjoy the fresh, light fragrance and think about how great your hair will feel afterward. Rinse thoroughly, and voilà—your hair will feel instantly softer and look visibly healthier!

Not only does it hydrate and smooth your hair for up to 72 hours, but it also provides heat protection for those who love their blow-dryers, straighteners, or curling irons. It’s perfect for anyone who wants smoother, shinier hair with minimal effort.

For those wondering about “Olaplex which one to buy” for the ultimate frizz-fighting power, No. 6 might just be your new go-to for easy Olaplex treatment at home!
Olaplex No. 6 is an excellent pick for anyone struggling with frizz or unruly hair, especially if you have curly, wavy, or thick textures that need a bit of extra moisture and control. It’s also a great choice if you’re exploring Olaplex for home use and want a product that works on its own or as part of a full Olaplex routine. If you’re on a mission to control frizz, add softness, and keep things smooth and manageable, No. 6 is a lifesaver.
To use No. 6, apply a small, pea-sized amount to damp or dry hair, focusing on the mid-lengths to ends where you need the most control. It’s lightweight and super easy to spread, so it won’t leave your hair feeling heavy or greasy. Since it’s suitable for daily use, you can reapply as needed to keep frizz at bay and maintain smoothness throughout the week. For an even bigger impact, pair No. 6 with other Olaplex products for a complete Olaplex treatment at home – you’ll be amazed at how soft and healthy your hair feels!
If you’re looking for a little extra shine and protection, Olaplex No. 7 is the answer.

Applying No. 7 is as easy as it gets! Just put a few drops into your hands, rub them together, and smooth the oil through your hair. For an ultra-sleek look, try pairing it with Olaplex No. 6 Bond Smoother. Together, they’re the ultimate duo for taming frizz and adding a glass-like shine. Whether you’re styling damp hair before a blowout or adding a finishing touch to dry, styled hair, Olaplex No. 7 is the final step you didn’t know you needed.
Think of Olaplex No. 8 as your go-to “spa day” treatment for your hair. This moisture-packed mask works wonders, giving your locks the hydration they’re craving while restoring shine and that soft, healthy look. Unlike other masks, this one goes beyond surface-level conditioning—it repairs damage while locking in moisture, so your hair doesn’t just look good; it actually feels stronger and healthier.
If you’re looking to give your hair some much-needed TLC with Olaplex for home use or need a powerful Olaplex treatment at home, No. 8 is your answer. It combines Olaplex’s bond-building magic with an extra kick of moisture that dry, damaged, or brittle hair needs.

It’s designed for hair that requires an intense, moisture-rich treatment to look and feel its best.
Using No. 8 is super simple and hassle-free, making it perfect for an easy Olaplex treatment at home. After shampooing (and maybe using Olaplex No. 4 and No. 5 to keep that bond-repair going), apply No. 8 to damp, clean hair. Let it sit for around 10 minutes—just enough time to relax, scroll through your favorite sites, or even catch up on a show. Then, rinse it thoroughly, and voilà! You’re left with instantly softer, shinier hair. To maintain that smoothness, try to use it once a week.
When it comes to choosing the right Olaplex products, there’s no one-size-fits-all answer. It all boils down to your unique hair type and what you’re hoping to achieve. Whether you’re dealing with frizz, dryness, or just want to up your hair care game, Olaplex has something for you. Let’s dive into some easy-to-follow recommendations so you can pick the best Olaplex treatment at home without any guesswork.
If your hair feels brittle, over-processed, or just super thirsty, you’ll want to go for a combo that targets deep repair and hydration. Start with Olaplex No. 0 and No. 3 as a pre-wash treatment. No. 0 is like a primer that boosts the power of No. 3, so together, they work wonders on really damaged hair. For cleansing and conditioning, use No. 4 (Bond Maintenance Shampoo) and No. 5 (Bond Maintenance Conditioner) regularly. They’re gentle, packed with bond-repairing ingredients, and keep your hair soft and manageable over time.
Curly and frizzy hair types know the struggle of keeping things smooth and defined. Here’s where Olaplex No. 6 (Bond Smoother) comes to the rescue. It’s a leave-in treatment that fights frizz, adds hydration, and even speeds up blow-dry time. Top it off with a few drops of No. 7 (Bonding Oil) for extra shine and heat protection. No. 7 is lightweight and doesn’t weigh down curls, so it’s perfect for finishing off your style with a smooth, glossy finish. This combo also works well if you’re into air-drying but want to avoid the poofy look.
If your hair is on the oilier side, or if it’s fine and prone to looking flat, you’ll want to keep things light. Stick with Olaplex No. 4 and No. 5 for regular washing and conditioning. They’re sulfate-free, so they’ll clean without stripping, but they’re also not heavy, making them safe for finer hair types. For those with really fine or oily hair, you might want to avoid heavier products like No. 8 (Bond Intense Moisture Mask). While it’s amazing for dry hair, it can be a bit much for finer textures.
If you’re just dipping your toes into the world of Olaplex and feeling a bit overwhelmed about Olaplex which one to buy, No. 3 (Hair Perfector) is a fantastic place to start. It’s a super versatile treatment that works for almost every hair type and addresses a wide range of issues, from damage to dullness. You can easily add it into your weekly routine for a noticeable improvement in your hair’s texture, strength, and shine. Plus, it’s compatible with most other Olaplex products, so it’s a great base if you want to build a more comprehensive Olaplex for home use routine.
One of the best things about Olaplex is that you can layer multiple products to tackle different concerns. For example, you could use No. 3 for overall damage repair and follow it up with No. 6 if frizz is also an issue. This kind of layering lets you target specific areas of concern without overloading your hair. It’s also a great way to test what works best for you and fine-tune your Olaplex treatment at home routine.
By picking the right products based on your hair’s specific needs, you’ll get the most out of Olaplex and enjoy salon-quality results at home.
Olaplex has truly earned its place as a go-to haircare solution, making it easier than ever to give your hair the professional-quality care it needs right from home. With their lineup of products, each targeting different hair concerns, there’s an Olaplex option for every hair type and goal. Whether you’re after major repair, added shine, frizz control, or simply maintaining healthy locks, Olaplex can take your hair from stressed and tired to strong, shiny, and resilient.
So, if you’re wondering Olaplex which one to buy, consider what your hair needs most. No. 3 is a fantastic starting point for anyone new to Olaplex, while other products like No. 6 and No. 7 are great for targeted treatments like frizz control and added shine. By choosing the right products and layering them for custom results, you can build an Olaplex treatment at home that fits seamlessly into your routine, giving you salon-worthy results without the salon price tag.
