My Hair Feels So Soft and Healthy Again!
Hair Type Wavy Hair
I love how soft and smooth my hair feels after using this conditioner. It helps repair damage and adds such a healthy shine. My hair looks stronger and feels silky every time I use it!

Perfect for my fine hair
Hair Type Straight Hair
I have a lot of fine hair. As I've aged and needed to *ahem* hide the gray, I've turned to coloring my hair, which of course leads to damage. While I only get it professionally colored and am careful to take care of my hair, I do end up with a bit of frizz and flyaways due to the mild damage. Most smoothing or moisturizing shampoos and conditioners, while they do take the frizz, weigh my hair down. I didn't have that with this Olaplex No. 4 shampoo. The shampoo lathered great, and cleaned my hair well without feeling stripped. And I loved the scent! Fresh, clean and lingers lightly. Makes me feel like I just came from the salon!


"So Lightweight Yet Strengthening — Love It!"
Hair Type Wavy Hair
This shampoo is a total game-changer for my fine hair. It cleanses without stripping, adds volume at the roots, and leaves my hair feeling stronger and more resilient. I love how lightweight it is — I no longer worry about hairs feeling weighed down. Disclaimer: I received this product as part of an educational promotion.


The Perfect Shampoo for Fine, Flat Hair!
Hair Type Wavy Hair
"I've been using the No.4FINE Bond Maintenance Shampoo for a few weeks now, and I'm honestly impressed! My hair feels super clean without being stripped, and it adds a nice lift at the roots. It's lightweight but still leaves my hair feeling strong and soft. I love that it doesn't weigh down my fine hair — just fresh, bouncy volume and a healthy shine!"


Great for long fine bleach blonde hair
Hair Type Wavy Hair
I have long fine bleach blonde hair with tons of frizz. My hair is easily weighed down with most haircare products including the original olaplex shampoo and conditioner line. I am SOOO happy they came out with this product line. The shampoo packaging is sleek and professional. The shampoo has the olaplex salon scent that every single one of their product has. It is not over powering like pureology can be. The scent is light and does not linger for hours post shower. It is easy to use and lathers well. I have been using this product for 7 days and it has helped my hair look less frizzy, healthier and smooth without weighing my fine hair down and taking away a ton of the volume. My hair is halfway down my back. So, most shampoos that will help with frizz will weigh it down a little bit but this is a drastically improved formula for fine hair compared to their regular line. Their regular line weighed my hair down. I took a before I started and after 7 days of use! I received this product for free in exchange for an honest review.
