Product details

Olaplex Number 9 Bond Protector Nourishing Hair Serum is a weightless, silicone-free leave-in styling serum designed to shield your mane from daily environmental stressors. Infused with antioxidant-rich Red Algae Extract and patented bond-building technology, this liquid formula neutralizes free radicals and blocks pollution for up to 48 hours. It is perfect for anyone dealing with dullness, tangles, or styling damage, making it suitable for all hair types from straight to coily, as well as color-treated locks.

This multi-benefit formula acts as a high-performance heat protectant, guarding your strands against styling temperatures up to 232 degrees Celsius. Beyond defense, it delivers noticeable styling memory, bounce-back curl retention, and an anti-static satin shine without weighing your hair down. By smoothing the cuticle, it facilitates effortless detangling and improves overall manageability.

Incorporating this clean, pH-balanced serum into your routine ensures your hair remains resilient, smooth, and visibly healthy.

  1. Apply a small amount, roughly half a pump, to damp, towel-dried hair.
  2. Work the serum evenly from the mid-lengths to the ends, then work any remaining product upward toward the roots.
  3. Do not rinse out.
  4. Style as you normally would by air-drying or blow-drying, or follow with your favorite styling products.

    Anti tangle!

    I always use a multitude of products to achieve my desired look. Yesterday I added this Olaplex serum to the list. Post shampoo/ conditioning I added some of this serum to my partially towel dried hair. I let it air dry the rest of the way. Then used a blow dryer for a few minutes to stretch my hair. I added big curls with a 1.75 in flat iron. Got caught in the rain at an outdoor concert. Wrapped my hair overnight & this pic is today's result. Shine, anti tangle & heat protection up to 450° are the advertised product descriptions that sold me... #LovingTheShine

    Curly Hair Approved

    I've tried every product under the sun and Opalex was honestly one of the LAST products I would've considered trying because brands like these usually have a lot of things that disagree with my hair type. This stuff is phenomenal. It smells amazing, it leaves my curls feeling soft and air light, doesn't cake them with product, keeps them defined. Even sleeping on curly hair and waking up in the morning is a pain because it frizzes up like nobody's business and I have to completely redo the curls but with the serum I woke up and was actually shocked at how in tact they remained. The bottle is expensive but it lasts a good while and goes a long way. Because of this serum I'm definitely gonna be trying the rest of their line and hopefully is as amazing as this was.
