Made my hair feel heavy
I was excited on trying this product out, I bought both the shampoo and conditioner. After one use I noticed my hair felt heavy and greasy, so I decided to give it another try and dear God it was worse. Never had my hair felt or even looked the way it did after washing it. Know my hair tends to get oily after just one day of washing my hair, but the way my hair felt right away after stepping out of the shower was insanely oily and heavy. I returned both products since it was not what I expected.
Bumpy scalp, waxy roots
This was the first product from Olaplex that was a complete no for me. I have thin, fine hair that gets bleached every 3 months. This shampoo seemed like the perfect formula for me, but couldn't have been any further from that! I ended up with multiple painful bumps throughout my scalp and my hair never felt clean. My roots always felt weirdly stiff and waxy after using this. I switched to a different shampoo and the issues have gone away, confirming this product was the cause.
Amazing
My hair is fine in texture and voluminous in quantity, a combination that makes finding the right shampoo a serious challenge. Most formulas designed for strength or moisture leave my roots feeling heavy and flat by the end of the day. The OLAPLEX No. 4 Fine Bond Maintenance Shampoo immediately felt different, a promising start to my experience. The product has a wonderfully light, almost watery consistency compared to the original OLAPLEX shampoo. This texture is key because it truly does not weigh my hair down. I was surprised by how much rich lather a very small amount creates. This concentration means the bottle lasts and lasts, a great value for the price. My hair feels amazing after using this and so clean it's now my go to that allows me to feel more confident!
I love this so much!
Hair Type Wavy Hair
This works amazingly well for my wavy hair! It cleans very thoroughly and also leaves it silky and beautiful! Wavy hair is hard to deal with so this shampoo in particular worked exceptionally well for my difficult hair type! I received this as part of an educational program and I love it!

Lightweight, strengthening, and shine-boosting
Hair Type Wavy Hair
This shampoo is a game-changer for fine, fragile hair. It gently cleanses while strengthening bonds and adding shine—without any heaviness. My hair feels cleaner, smoother, and more resilient after every wash. The scent is fresh and salon-like, and a little goes a long way.
