OLAPLEX No.4Fine Bond Maintenance Volumizing and Strengthening Shampoo

I received this product in exchange for my honest review. I have fine, slightly fragile hair, and I was genuinely impressed by how well this shampoo performs. From the very first wash, it gave my hair a clean, refreshed feeling without drying it out or weighing it down. The texture feels luxurious, and a small amount lathers beautifully. After a few uses, I noticed that my hair looked fuller, softer, and much stronger. It gives a healthy, natural shine and adds volume that lasts throughout the day. What I appreciate the most is how it strengthens my strands while still keeping them lightweight and bouncy. The scent is subtle, elegant, and leaves my hair smelling fresh — like I just left the salon. It pairs perfectly with the Olaplex conditioner, creating that smooth, glossy finish that's hard to achieve with fine hair. Overall, this shampoo exceeded my expectations. If your hair tends to get flat or break easily, this product truly helps to restore strength and volume while maintaining softness. I'll definitely continue using it in my routine.

Olaplex No.4 Bond Maintenance Shampoo for Fine Hair and No.5 Bond Maintenance Conditioner for Fine Hair — Not Suitable for Fine, Protein-Sensitive Hair I recently tried the Olaplex No.4 Bond Maintenance Shampoo for Fine Hair and No.5 Bond Maintenance Conditioner for Fine Hair after a salon stylist recommended them, assuring me they were ideal for fine hair and safe for occasional heat styling. Because I'm protein-sensitive, I contacted Olaplex via their live chat to confirm that these versions did not contain protein. The representative confirmed they were protein-free and suitable for daily use, even on fine hair. However, my experience was extremely disappointing. The shampoo lathered well but left my hair feeling rough and coated as I rinsed. The conditioner provided temporary softness in the shower, but once I combed through my hair, it was tangled, difficult to manage, and I noticed some breakage. After air-drying, my hair felt dry, stiff, and looked dull — very unlike the "hydrating" or "bond-repairing" results I was expecting. Upon reviewing the ingredient lists, I discovered Hydrolyzed Quinoa, which is a protein, and Isopropyl Alcohol, a drying ingredient — both unsuitable for fine or protein-sensitive hair. In my opinion, these products are not appropriate for daily use on fine hair, and they certainly aren't protein-free. I would not recommend Olaplex No.4 Bond Maintenance Shampoo for Fine Hair or No.5 Bond Maintenance Conditioner for Fine Hair to anyone with fine or protein-sensitive hair.

Im really enjoy this Shampoo , its working good on my hair . Its helps me looks much better, no frizz.

I have naturally fine hair that tangles easily, and this shampoo worked perfectly for me. It made my hair airy, bouncy, and shiny without weighing it down. After a few washes, I noticed my hair became more manageable and less frizzy. It has a pleasant, clean scent and gives that "soft and flowy" look I've been searching for. I received this product as part of an educational promotion.

This shampoo is the best I have ever used. I frequently bleach my hair and kinda put it through the ringer when it comes to heat tools but since ive used this shampoo, my hair has honestly felt completely different. It feels SO healthy and so strong that I honestly never want to use a different shampoo after using this. It has healed my hair tremendously….so much so that my hair has even started growing again. I highly recommend this to anyone who suffers from a lot of breakage, bleaches their hair, has dry or damaged hair, or someone that uses a lot of heat on their hair. Its transformed my hair texture and smells incredible. I was sent this product in exchange for my honest review.
