How is Olaplex 9 different to other Olaplex products?

Olaplex 9 is a hair styling product for use AFTER you wash your hair. Olaplex 6 and 7 are also post wash styling products.

In comparison, Olaplex 0 and 3 are pre shampoo treatments. Olaplex 8 is an intense moisture mask. Olaplex 8 should be used AFTER shampooing your hair.

If you are only buying one Olaplex product, I recommend buying Olaplex 3 for the ultimate damage repair. If you are buying two Olaplex products, I recommend buying Olaplex 3 and Olaplex 8 for damage repair and hydration. If you are looking for a hydrating hair product, Olaplex 8 is an amazing mask for adding moisture to your hair. I love using Olaplex 8 and am definitely going to continue using it along with my other Olaplex products. I would recommend Olaplex 0, 3 and 8 if you have damaged and dry hair.

If you are looking for a specific styling product, my favorite Olaplex styling product is Olaplex 6, followed by Olaplex 9. Both are great products with great results, however, I find that Olaplex 6 hold my hair better and eliminates frizz.

Olaplex 6 vs 9

Learn more about Olaplex 9 in these Olaplex 9 Reviews. I'll share how to use Olaplex 9, is Olaplex 9 worth it and Olaplex 9 results. I'll also share more on Olaplex 6 vs 9 which is a popular Olaplex question.

Olaplex 6 and 9 are both styling products for use after washing your hair. There is a texture difference between Olaplex 6 and 9: Olaplex 9 is thicker serum, while Olaplex 6 is a cream.

Olaplex 6 is designed more as a traditional styling product to smooth, condition and strengthen, while reducing frizz.

Olaplex 9 is more a nourishing hair serum similar to skin care serum, which provides replenishment and repair. Both Olaplex 6 and 9 offer heat protection and will benefit your hair.

I use both Olaplex 6 and 9 as hair styling products. If you only want to buy one product, I prefer Olaplex 6 as a styling product as it works better for reducing frizz for me. I also use Olaplex 3 to repair my hair prior to shampooing.

My hero Olaplex product overall is Olaplex 3 and my hero styling product is Olaplex 6. I do really like Olaplex 9 also if you are open to buying multiple Olaplex products.

More top tips to keep your hair in amazing condition

Hair is most vulnerable when it is wet so it is important that you treat it with care when drying it (no vigorous hair drying with a towel)! I love the new Cozy Earth hair towel. It ties neatly on your head and allows the water to soak into the towel with no rubbing. This saves your hair mechanical damage. My Cozy Earth discount code CE-LORNA gets you 45% off everything on Cozy Earth including this hair towel.

I also LOVE their new silk pillowcase. It is so soft and gentle on your hair. Friction with cotton also causes breakage so a silk pillowcase is a great investment. Silk pillowcases also help with reducing frizz. Curly hair tends to get frizzy with the friction of cotton, but silk will help the hair glide instead. You can get this silk pillowcase for 45% off using my Cozy Earth discount code CE-LORNA for a limited time. Read more about the benefits of silk pillowcases.

Summary of my Olaplex 9 Review

I recommend treating yourself as I love Olaplex 9. It really repairs my hair, provides multiple uses per bottle and it is a clean hair care product. Olaplex 9 features antioxidant-rich Red Algae Extract and scientifically proven Olaplex bond building technology, giving the hair satin shine, softness, style memory, bounce back curls, anti-tangle and anti-static.

As I mentioned above, I also really love Olaplex 6 as a hair styling product. I use both of these products together for the ultimate styling.
