Which is better: Olaplex 6 vs 9

Before we get into Olaplex 6 vs 9, I am going to go through the differences between Olaplex 6 and 9.

The differences between Olaplex 6 and 9

When deciding whether to buy Olaplex No 9 v No 6, it is important to note that Olaplex 9 is used as a serum (kind of like a serum for your face that adds extra nourishment before moisturizing). It is used as an antioxidant serum that protects, softens and improves manageability of hair.

Olaplex 6 is used as a styling treatment that adds moisture, strengthens and reduces frizz for up to 72 hours. Olaplex 6 is leave-in styling treatment that softly defines and smooths air dried curls.

Olaplex 9 is a serum and Olaplex 6 is a cream. Similar to skincare, these products do different things. The serum is for nourishment and protection. The cream is for moisturizing and smoothing.

Another difference between Olaplex 6 and 9 is that Olaplex 9 provides heat protection up to 450ºF (232ºC) for a satin shine look. Olaplex 6 does not offer heat protection.

There are so many benefits to both Olaplex 6 & Olaplex 9.

Olaplex 6 benefits:

  • Speeds up blow dry time while smoothing
  • Softly defines and smooths air dried curls
  • Reduces frizz and flyaways for up to 72 hours
  • The airless pump delivery system ensures every dose of definition and smoothness is dispensed.

Olaplex 9 benefits:

  • Neutralizes free radicals and protects against pollution for up to 48 hours
  • Improves style memory and bounceback curls
  • Provides Heat protection up to 450ºF (232ºC) for a satin shine look
  • Reduces tangles and static.

The final difference between Olaplex 6 and 9 that I want to highlight relates to curly hair. Olaplex 9 gives minimum hold as it’s a serum, compared to Olaplex 6, which is a leave in styling treatment and gives more hold.

Choosing between Olaplex no 6 v 9 depends on your hair concerns and hair goals.

Deciding on Olaplex 6 or 9

Now that you know the difference between Olaplex 6 and 9, it is hopefully easier for you to decide on Olaplex 6 or 9. The most important question to ask when deciding between Olaplex no 6 vs no 9 is to check if you want a styling cream or a serum for extra nourishment.

Olaplex no 6 is a great styling product. I find this controls my hair better versus just using Olaplex 9 on it’s own. Both Olaplex 6 and 9 will work to repair the hair. Our hair gets damaged from color, too much sun, brushing too roughly, pool water, cold weather and much more.

If you are looking for more protection for your hair (including heat protection), then Olaplex 9 is a better option. If you are looking for a hair styling treatment to help with smoothing and frizz control, Olaplex 6 is a better option.

If you don’t have to decide between Olaplex 6 and 9 and can afford both, then I would invest in both Olaplex 6 and Olaplex 9. A little goes a long way and Olaplex 6 and 9 work amazingly together to protect and strengthen your hair.

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-LORNARYAN gets you 40% 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 40% off using my Cozy Earth discount code CE-LORNARYAN for a limited time. Read more about the benefits of silk pillowcases.
