New Olaplex No. 9: In-Depth Review

What is Olaplex No. 9?

Olaplex No. 9 is a protective hair serum, making it the first hair serum in the Olaplex collection. Using the brand’s world-renowned bond technology, Olaplex No. 9 helps shield the hair from external damage (such as pollution and heat), helping you to protect your locks while creating shine and softness. If we consider Olaplex No. 3 to be our go-to hair product for fixing already-damaged hair, Olaplex No. 9 is what you use to prevent further damage on healthy hair. Put simply, Olaplex No. 3 is the remedy, while the new Olaplex No. 9 is the prevention. This hair serum even helps protect the hair against heat, making it the perfect addition to your summer haircare routine.

What is Olaplex No. 9 Good For?

Besides protecting your hair, Olaplex No. 9 is great for adding shine, diminishing frizz, and treating hair damage. If your hair feels dull, lifeless, and easily breakable, it’s most likely damaged from heat, pollution, or over-styling. Damaged hair can become brittle and dry over time, and Olaplex is the gold standard when it comes to reversing hair damage. The bond-repair technology in all Olaplex products uses disulfide bonds to restore the hair’s strength and structure, with a patented system that has been scientifically proven to reverse hair damage while providing softness, shine, and a naturally smooth texture. This serum is also enriched with red algae extract for extra antioxidant benefits.

Why We Love It:

What’s great about this hair serum is that it’s incredibly versatile. Even if you don’t have damaged hair, the antioxidant-rich formula and world-famous Bond technology are going to protect your hair from the damaging impact of heat styling and pollution. This product is also vegan, cruelty-free, silicone-free, sulfate-free, paraben-free, and pH-balanced.

What Hair Types Should Use Olaplex No.9?

All hair types! Whether your hair is curly, straight, wavy, fine, or thick, you can use Olaplex No. 9. For heat protection, this hair serum is best used on slightly damp hair before drying and styling, but all hair types can also use it in between washes for some added shine and bounce. If you have oily hair, you might want to use it only at the roots or ends of your hair to avoid any product build-up, but you can definitely still add this serum into your haircare routine and enjoy great results.

How to Use Olaplex No. 9?

So, you might be wondering how to use Olaplex No. 9. If you want optimal results, here are the best ways to use this hair serum in your haircare routine:

On wet hair:

• After shampooing and conditioning your hair, gently pat it dry with a towel. Don't rub your hair aggressively - this can cause breakage and hair damage.
• Before drying or styling with heated tools, apply a small amount of the hair serum to your fingers and apply to the hair, working the product into the hair at the ends and finishing at the roots. If your hair is long or thick, you should use a little more serum where necessary.
• If you want a sleeker finish, style your hair with hair tools or blow dry the hair.
• For a smoother texture, allow your hair to dry naturally.

On dry hair:

• For quick protection on the go, apply to the hair in between washes, before or without styling. Olaplex No. 9 helps your hair hold its style, so it can even be used as a hair primer.
• BeautyPro Tip: Always apply hair serum from the ends of the hair to the roots, not the other way around. This will prevent your hair from looking greasy following the application.
