Description
Olaplex No.9 is a 90 ml leave-in nourishing serum that protects hair from heat and gives it softness and shine. It is weightless, silicone free and suits all hair types and textures. Use it as the first step of your styling routine.
What is Olaplex No.9?
Olaplex No.9 is a reparative, nourishing hair serum built on the patented Olaplex bond building technology. It contains red algae extract, which is rich in antioxidants and forms a protective layer on wet hair. The serum guards hair against daily damage and pollution, and the protection lasts up to 48 hours.

The formula protects against heat up to 232 °C, which is 450 °F. It also reduces tangles, static and frizz, and helps curls bounce back. The serum is vegan, cruelty free, pH balanced and gluten free.
How to use
- Apply a small amount to damp hair, working upward from the ends to the roots.
- Use more for longer or thicker hair.
- Use the serum on wash days and on the days in between for added protection.
- Then finish your style the way you like it: blow-drying, straightening or shaping curls.
A familiar order gives a good result: cleanse with Olaplex No.4 shampoo, care with No.5 conditioner, then apply serum No.9 to damp hair.
Who this serum is for
No.9 is made for all hair types and textures. It suits people who use a hair dryer or straightener regularly and want to protect their style. It works just as well on curly hair, where the serum helps curls keep their shape. The weightless texture adds no heaviness to the hair.
Besides protection, the serum gives softness and shine. Hair feels smoother and tangles ease when you comb. Static is reduced, so hair stays calmer even on a dry winter day.
Everyday care in a few movements
Good hair care does not have to take long. The pump gives a precise amount of serum and the whole process takes a moment. After a shower, comb through damp hair, spread the serum from the ends upward and carry on with styling. Protection from heat becomes part of your normal morning rather than a separate chore.
The serum works with long and short styles alike. If your hair needs more care, increase the amount to match its length and thickness. For a light finish, a small amount is enough. Used regularly, it helps hair look good on the days between washes too.
A lovely gift for a hair care fan
Olaplex is a familiar name to people who care about their hair. If you know someone who loves hairstyles or reaches for the hair dryer and straightener often, No.9 is a thoughtful gift. The compact 90 ml bottle fits neatly into a gift bag. Together with No.4 and No.5 it makes a three-part set that covers washing, care and styling.
Part of the Olaplex care system
Olaplex No.9 completes No.4 shampoo and No.5 conditioner with a styling step. While the shampoo cleanses and the conditioner cares, the serum protects hair at the moment you work with it. Olaplex No.9 ties the routine together and gives your care a logical finish. Three steps form a habit that is easy to remember and pleasant to repeat.
Texture and feel
The serum is clear and light, and it spreads easily through damp hair. Its soft feel turns an everyday routine into a pleasant moment. Hair stays free-moving because the formula does not weigh it down. A good texture and a weightless finish are why the serum fits both everyday routines and more special styles.
