Product Description

Highlights Sephora badge
This ultra-lightweight, heat-protective hair styling serum creates a satin shine and lasting style retention while reducing tangles and static. Plus, it provides immediate pollution protection. Pollutants can bind to hair and cause free radical damage that affects the appearance of hair health. No.9 shields hair from pollutants for up to 48 hours.

Clinically Proven

Instantly shields hair from pollution

48 Hr OLAPLEX Pollution Protection Index™

Directions

1. Apply a small amount to clean, damp hair working upward from ends to roots. Use more as needed for longer, thicker hair.
2. Style as usual. Air-dry for a soft texture. Blow-dry for a smooth finish. Diffuse for defined waves or curls.

Rated 5 out of 5 by from Use sparingly Store the bottle upside down for easy use. A little sticky but does an excellent job at protecting the hair. Don’t use on scalp if you have thicker hair as it’ll weigh it down

Rated 3 out of 5 by from Good for shine and volume It’s ok but dosent control the fizziness of my hair so it’s not incredible but it works in detangling and keeping my hair straight after I get out the shower

Rated 5 out of 5 by from Olaplex is the best! I love love love olaplex! I use this on my newly washed damp hair alongside the no. 6 and no.7. It becomes soft manageable, non frizzy and with the added bonus that no.9 detoxifies and is also a heat protectant. Very happy!!
