Olaplex No. 0 Intensive Bond Building Treatment ($24, originally $30)

Depending on how dry or damaged your hair is, you can use this Olaplex No. 0 Intensive Bond Building Treatment to intensify the effects of the brand's No. 3 formula. The product helps prep the hair to absorb ingredients, which results in longer-lasting hydration and shine. It's especially great for those with curly hair who limit their washes to only once or twice per week, as it's recommended that users work this formula into their hair-care routine two times each week.

Olaplex No. 3 Hair Perfector ($24, originally $30)

Easily the most popular product in the brand's entire lineup, the Olaplex No. 3 Hair Perfector is so effective that even a few of our own editors have sang its praises; read through our review of the Olaplex Hair Perfector No. 3 for further proof. It uses a special bond-building technology to repair damaged or color-treated hair. It shouldn't be used as a conditioner but rather as an intensive mask for anyone with severely damaged hair from chemical treatments. To get the best results, you should apply it to the hair at least twice a week before following it with your shampoo and conditioner.

Olaplex No. 4 Bond Maintenance Shampoo ($24, originally $30)

The Olaplex No. 4 Bond Maintenance Shampoo is a favorite among hairstylists. The shampoo can be used on damaged, dry, or even severely color-treated hair, and it uses a special technology to relink the bonds in the hair to ultimately make it stronger and healthier. It's great for all hair types, which we love. And to see the best results, the retailer simply recommends that users massage the product across their scalp and rinse it out with water once it's settled long enough.

Olaplex No. 5 Bond Maintenance Conditioner ($24, originally $30)

As you can probably guess, the Olaplex No. 5 Bond Maintenance Conditioner is meant to be used as a follow-up to the shampoo. Much like the shampoo, it works to strengthen damaged hair while also making it appear shinier and easier to manage. The sulfate-free formula aims to address a range of hair concerns including everything from repairing split ends to minimizing frizz. It's one of the best Olaplex products for seeing fast results, and all you have to do is massage a generous amount of the formula across your scalp and through your hair's ends, let it sit for three minutes before rinsing, and then prepare to see immediate shine.

Olaplex No. 6 Bond Smoother ($24, originally $30)

For people with curly and wavy hair, or hair that's prone to flyaways, the Olaplex No. 6 Bond Smoother is a solid leave-in product that can be applied to damp or dry hair. It's meant to strengthen and hydrate the hair and can help keep frizz to a minimum for at least three days post-use. Besides helping to make your hair look healthier, it also works to repair broken ends and strengthen the hair so that it can grow back stronger.

Olaplex No. 7 Bonding Oil ($24, originally $30)

Often used as the last step in the Olaplex process, the Olaplex No. 7 Bonding Oil can be applied before or after blowing out your hair to prevent frizz, heat damage, and split ends. If your hair is color-treated, you can also use this product to protect the color's vibrancy. While it's hard to narrow down the overall best Olaplex product, this formula is definitely a winner for us thanks to its highly concentrated yet still lightweight feel. Plus, you only need a few drops of the solution before you can start to see (and feel) a real difference.

Olaplex No. 8 Bond Intense Moisture Mask ($24, originally $30)

As the name suggests, the Olaplex No. 8 Bond Intense Moisture Mask is a conditioner substitute that's meant to target damaged hair, and according to one POPSUGAR editor who previously tried it out, it's able to work wonders on dry and brittle hair; just read our review of the Olaplex No. 8 Bond Intense Moisture Mask for further proof.

Olaplex No. 9 Bond Protector Nourishing Hair Serum ($24, originally $30)

Unlike other Olaplex hair products, this serum is designed to be used on the daily as a protectant for everything from pollution to heat damage. Per the brand's recommendation, you can use the product on wash days (and any days in between) to ensure your hair is coated in an extra layer of protection. Over time, the formula is said to help hair grow back stronger, retain its natural bounce, and boast a more nourished shine.

Olaplex Lashbond Building Serum ($68)

Olaplex's commitment to giving you stronger, shinier hair has officially reached a whole new level with the brand's latest launch: the Olaplex Lashbond Building Serum. Designed to give users healthier-looking lashes in as little as two weeks, this product essentially takes everything we love about Olaplex's shampoos and conditioners, and bottles it up into a more lightweight serum that aims to increase the volume, look, and overall health of your eyelashes. What's not to love about that?

Olaplex Volumizing Blow Dry Mist ($30)

The Volumizing Blow Dry Mist is Olaplex's first-ever styling product, and it's perfect for getting that coveted bouncy blowout. It helps speed up drying time and protects hair from heat up to 450 degrees. It's made with Olaplex's bond-building technology, which is said to help promote healthier hair.
