Nº.9 Summer Hair Prep: Heat Protection & More

The spring-to-summer transition is approaching, which means your hair may be showing more signs of pollution and heat damage. Just as you switch up your skincare routine and serums as seasons change, it’s time to elevate your routine to protect and nourish your hair.


Protect Your Hair from Pollution and Heat Damage

If you notice poor style retention, tangles, or overall dullness, these could be signs of pollution or heat damage in your hair. Whether or not we like it, as soon as we’re outside, our hair is subject to the elements of the environment. Exposure to free radicals can cause a breakdown in the protein in the hair. OLAPLEX® Nº.9 Bond Protector Nourishing Hair Serum protects hair from daily damage, shielding it from pollution while also providing heat styling protection. This weightless, leave-in hair serum is your summer hair-love go-to to keep your hair feeling and looking healthy. It’s what your hair needs right now to stay healthy! Nº.9 acts as a hair shield to protect hair from pollution for up to 48 hours and guard against heat styling damage up to 450ºF degrees that causes tangles, breakage, and static.


How to Apply Nº.9

Nº.9 is the first step of your styling routine. After washing your hair with OLAPLEX Nº.4 and Nº.5 Bond Maintenance® Shampoo and Conditioner, apply a pump of Nº.9 all over damp hair. Work upwards from ends to roots until the product is dispersed evenly throughout the hair. You’re welcome to add more if necessary. We like to continue with Nº.6 Bond Smoother® for frizz control and OLAPLEX Nº.7 Bonding OilTM for a smooth, protected, shiny style. Nº.9 can be used as often as necessary.


Many people apply Nº.9 after they wash their hair to ensure the hair is protected between each wash. Wondering if you can apply Nº.9 on dry hair? For best results, Nº.9 should only be used on wet or damp hair. Between wash days, you can dampen your hair if you want to reapply Nº.9.


OLAPLEX Nº.6 vs Nº.9: What’s the Difference?

While Nº.9 protects your hair from hot tools and pollution, reach for No.6 to help reduce frizz and flyaways for up to 72 hours. Nº.6 Bond Smoother® is a nourishing, humidity-resistant, smoothing styling cream that hydrates, softens, and repairs frizz-prone hair types without adding excess weight. Can you use Nº.6 and Nº.9 together? Yes. We recommend using Nº.9 first and following it with Nº.6.


A Summer Hair Routine That Has It All

Your summer styling routine can have it all—protection, anti-frizz, shine, moisture, and health. Protecting your hair from pollutants means hair that’s easier to manage in the summer. There are enough ways to damage your hair; why let pollutants be one of them? Treating and protecting now means a stronger foundation to withstand the hot weather and summer elements ahead.
