Varied results
I have fine (and thinning) hair so it's nice to have a formula specifically for this need. The scent is fresh, clean, and citrusy without being overbearing. I did notice it doesn't suds up/lather very nicely so it's doesn't feel like it's doing a good job as you apply to scalp and hair in shower but...

As someone with fine, color-treated hair, I've always struggled to find a shampoo that provides a deep clean without stripping my strands. Olaplex No.4 hits a great balance—it cleans thoroughly while still feeling gentle and nourishing. It has a rich, slightly creamy texture, but it doesn't weigh my hair down or leave any residue. After a few weeks of use, I noticed less breakage and smoother ends, which is a game-changer for fine hair prone to damage. The scent is pleasant and not overpowering. I only need a small amount to get a good lather, so the bottle lasts quite a while. Overall, it feels like a salon-level product that helps strengthen my hair from the roots. Rating: 4.5/5
Amazing
Olaplex No.5 Bond Maintenance Conditioner is a great option for fine hair, as long as it's used with a light hand. The formula is rich and ultra-nourishing, designed to repair and strengthen damaged hair, but it won't weigh fine strands down if applied just from mid-lengths to ends. It leaves hair feeling soft, smooth, and visibly healthier, with less frizz and fewer tangles. I noticed improved manageability and strength after a few uses, and it pairs especially well with the No.4 shampoo. Because it's highly concentrated, I only needed a small amount! It rinses clean and doesn't leave a residue, but for fine hair, I recommend using it every other wash or as needed to avoid buildup. Overall, it's a high-quality conditioner that delivers professional-level results at home!
Love my hair
Hair Type Wavy Hair
I recently tried the Olaplex No. 4FINE Bond Maintenance Shampoo and was genuinely impressed. After just one use, my hair felt incredibly soft, clean, and noticeably more voluminous. It's designed specifically for fine hair, and I love how it adds body and bounce without weighing my hair down. The patented bond-building technology helps strengthen and repair from the inside out, making my strands feel healthier with every wash. I have been using Olaplex shampoo for a while now, and this one is definitely my new favorite. I Love this brand for its innovative formulas and consistent results and I highly recommend it if you want your hair to feel revived and full of life!

Game-Changer for Fine, Blonde Hair and Extensions
Hair Type Straight Hair
As a blonde with fine hair and extensions, I'm super picky about shampoos—and No.4 FINE Bond Maintenance® does not disappoint. It gives my natural hair strength and volume without weighing down my extensions. My blonde stays bright, my bonds feel secure, and there's zero heavy residue. It leaves everything feeling clean, soft, and airy with the perfect amount of lift. I've noticed my hair feels stronger and looks fuller after just a few washes. Plus, it smells amazing! If you have fine hair, extensions, or both, this shampoo is a total must-have.
