Nº.9 Summer Hair Prep

The Spring to Summer transition is approaching, which means your hair is 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 bonds. OLAPLEX Nº.9 Bond Protector Nourishing Hair Serum protects hair from daily damage with a weightless, leave-in silicone-free hair serum that shields hair from pollution for 48 hours while also providing heat protection up to 450ºF. It’s what your hair needs right now to stay healthy!


If you notice poor style retention, tangles, or overall dullness, these are all 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. The more exposed the hair is to free radicals, the more the bonds in our hair break. Nº.9 acts as a hair shield to protect the hair from pollution for up to 48 hours by neutralizing free radicals.


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, towel dry until the hair feels damp. Apply a pump of Nº.9 all over the hair, distributing evenly. 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 OLAPLEX Nº.6 and Nº.7 afterwards for a smooth, protected, shiny style. Nº.9 is safe to use as often as necessary. Many apply after they wash their hair, to ensure the hair is protected between each wash.


Your 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 have pollutants be one of them? Treating and protecting now, means a stronger base for the harsh hot weather ahead.
