This product saved my hair.
A little backstory on my hair journey; I had never really used heat tools other than a hairdryer on my hair before this past year, which is when I finally found a curling iron that would actually work for my hair (I have very fine very straight hair) so of course I was super excited. I curled my hai...

Overhyped for My Thick, Bleached Hair
I'm writing this as a general review of Olaplex products, including No. 9. I've used most of their standard products (#No. 0, 3–9), and overall, I was very disappointed.

Overhyped for My Thick, Bleached Hair
I'm writing this as a general review of Olaplex products, including No. 9. I've used most of their standard products (#No. 0, 3–9), and overall, I was very disappointed. For reference, I have thick, color-treated (bleached) hair that air-dries mostly straight with loose waves in the back and tends to feel dry and frizzy without styling products. I'm someone who reads multiple reviews before purchasing hair, makeup, or skin-care products—especially at a higher price point—so after seeing so much praise for Olaplex, I was genuinely excited to try the line. Unfortunately, I didn't notice any improvement in softness, moisture, or overall hair feel. If anything, my hair felt drier rather than healthier. To be fair, I didn't use the products long enough to determine whether extended use would have changed the results, but based on my experience, they simply didn't work for my hair.
So underrated!
Hair Type Straight Hair
I have thin, bleached highlights. This serum makes my hair shine a LOT! Hair becomes smooth and keeps curls after blow-drying. Love it!!!!!!
Underrated product!
I use this hair serum when I'm curling my hair and I want it to stay all day. I have fine long hair and it drops a curl almost as I'm doing it. When I use this product it keeps the curl without crunchy hairspray or other products that weigh down the hair. I've used it in dry and humid climates. The humid climate was a little bit of a struggle but it still maintained better than anything else I've tried. I actually convinced my sister to try it but straighten her hair. She's polar opposite of me lol She has insanely thick, curly hair. We straighten her hair one day using the serum. Her hair was actually smooth (not frizzy) and stayed straight for over 3 days (no hair washes). She was so impressed with it she was telling her friends.
on a whim
Hair Type Wavy Hair
I grabbed this off the shelf on a whim. I didn't really go into the store for it. I love it! It encourages the waves in my hair, helps with frizz, and makes my hair look SO healthy
