The science behind Olaplex No.9

Let’s get to the nitty-gritty of exactly how this serum works, shall we? First, it contains moisturizing ingredients like hyaluronic acid and panthenol that bind to strands to hydrate dry, damaged hair. The star of the show, however, is red algae from the south of France, which “is a very powerful antioxidant that protects against different free radicals”, according to Lavinia Popescu, chief scientist for OLAPLEX. This gives the serum the ability to absorb any unwanted free radicals before they reach your hair, just like your favorite antioxidant serum would your skin.

Plus, this formula contains film-forming polymers that neutralize free radicals for up to 48 hours and even protect hair against heat styling up to 450° Fahrenheit. Dr. Zeichner adds, “The polymers in hair care products coat the surface of the hair to hydrate, protect, reduce frizz and improve shine.

My first impression of Olaplex No.9

When I received the serum I have to admit it was a great unboxing day. To start with, I was shocked at the size of this product – at 90ml it’s about twice the size of most hair serums I currently have in my collection.

I was also impressed by the lightness of the texture: it has the same consistency of a watery gel serum that one would use on the skin, without any slimy and oily residue that most hair products in its category tend to to offer. Plus, it’s virtually fragrance-free, making it ideal for those who are sensitive to scents.

How to use Olaplex No.9

Popescu recommended that I apply Serum #9 to damp hair, starting an inch from the scalp and working down to the ends (when OLAPLEX Chief Scientist tells you to do something, you Listen). Popescu reveals that it’s essential to apply this serum to damp hair, stating that “when the hair is wet, the cuticles are more open, and the product can work its way under the cuticles and protect against pollutants both outside and outside. outside than inside.” I use it after every wash since I wash my hair every other day. If you *wash* your hair less frequently than I do, OLAPLEX recommends re-wetting your hair between washes to reapply every 48 hours.

Since this formula is water soluble, it is quite thin. Best used early in your styling routine, before applying other creams or oils.

After my first application, I was pleasantly surprised that my hair didn’t look or feel weighed down. at all. It felt like there was nothing in my hair, but I could see that my curls looked shinier and healthier. I didn’t notice a ton of extra definition in my texture immediately, but after using this product plus hair oil for three weeks, my curls are more defined and my ends look and feel stronger. Plus, the results are long lasting – my hair stayed soft and shiny between washes.
