‘Miracle’ Serum

Now I see why everyone is raving about! This serum is lightweight, smells incredible, and does exactly what it says… I have shoulder-length wavy/curly hair and it can be unruly at times, especially in humid climates. I put maybe two pumps of this “potion” in my damp hair and gave it 30 minutes - SHAZAM! I cannot wait to see how it will restore my locks after utilizing it overtime. To be honest, I had prior damage due to dyeing for almost a year. To me, the smell is light and a citrusy floral blend that is great for the Summer! Thank you!

After shampooing and conditioning, I apply this serum to my hair, and it instantly feels smoother and tangle-free. It’s also great on dry hair for an extra boost of moisture and shine. It doesn’t weigh hair down, making it more manageable and healthier-looking as part of my hair care routine.

I absolutely adore this serum! It's the first time I’ve ever reordered it twice. A little goes a long way, and it feels amazing. I use it at night as part of my routine.

This has become my go-to styling product! It makes my hair smooth without being limp, and the scent is light and pleasant.

I love how this product protects my hair from heat, reduces frizz, and even adds some texture. It’s a staple in my routine.

Luna

This is my must-have for silky smooth hair, even in humid weather. It’s my go-to every time!

No. 9 is an excellent lightweight serum and heat protectant. When I apply it to damp hair and let it air dry, my hair is smooth and soft. Adding a couple of drops of bonding oil to it creates an even better result.

H
Harper

My fine, slightly thin, and flyaway prone hair feels transformed with this product. I work No. 9 into the ends, or mix it with No. 6 and apply it from root to tip. It smooths everything out without leaving my hair greasy unless I overdo it! I’ll definitely keep this on hand.

Since incorporating multiple Olaplex products into my routine, my hair has never looked better. No. 9 keeps my hair light and bouncy while protecting it during blow-drying. Highly recommend!

This is hands down the best after-shower hair product! It smooths, adds shine, and offers great protection while styling. Absolutely love it!
