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...

Quality shampoo
Hair Type Wavy Hair
This is a solid pick for anyone with fine or thinning hair. It delivers noticeable volume and a clean feel without weighing hair down. My hair felt stronger after a few uses, and I appreciated that it didn't leave any residue. It's a bit pricey, but a little goes a long way, so the bottle lasts. If you're looking for a reliable shampoo that actually does what it claims - without being overly perfumed or harsh - this is a good option. *I received this product as a gift in exchange of my honest review
I would buy this product again yes and yes

Gifted for promotional purposes — this review reflects my honest opinion. I've been using the No.4Fine Bond Maintenance Volumizing and Strengthening Shampoo, and I have to say I'm genuinely impressed. My hair tends to fall flat easily, but this shampoo gave it a noticeable lift without weighing it down. It has a lightweight formula that still feels nourishing and hydrating, which is great for my fine hair. What stood out the most is how strong and healthy my hair feels after just a few washes. It doesn't leave any residue, and the scent is clean and refreshing without being overpowering.

Bye bye limp hair
Hair Type Wavy Hair
From the first wash, I noticed a difference. My hair felt clean, but not stripped. It actually felt softer and less tangled even before I applied the conditioner. It smells so good too not too heavy or perfume but clean and nice. The conditioner, in particular, is where the magic really happens for me. It's rich and creamy, and a little goes a long way. After rinsing, my hair felt sooo silky and easy to comb through. The biggest benefits I noticed is the reduction in breakage, and the volume, and shine. It's soft and moisturized but not weighed down or oily looking. My hair used to shed quite a bit, especially when wet, but since consistently using Olaplex I've seen a noticeable decrease. It feels stronger, looks healthier, and it looks so shiny and fuller, more lively it was definitely lacking volume and shine before. While it's certainly an investment, the results speak for themselves. For anyone with damaged or color treated hair, or density loss looking to bring it back to life, this duo is absolutely worth it. I got this as a part of a promotion.

Lightweight Volume for Fine Hair
Hair Type Straight Hair
I have fine, color-treated hair that tends to fall flat. This shampoo added volume and softness without weighing it down. It lathers well, smells clean, and rinses easily. After a week, my hair feels fuller, stronger, and looks more vibrant.


Instant volume
Hair Type Wavy Hair
I recently started using the Olaplex No.4 FINE Bond Maintenance Shampoo, and I'm impressed. I have medium-length, shoulder-grazing hair, and just a small drop of this shampoo is enough. It lathers well without over-stripping, and though it doesn't leave that ultra-smooth, slippery feel some shampoos do, it actually makes my hair feel stronger—even after the first wash. Over time, I've noticed a real difference: my hair feels filled out, shiny, and healthy. The ends are no longer breaking as they used to, and I love the instant volume boost it gives. My hair looks fuller right after washing, which is exactly what I was looking for in a daily-use shampoo. If you have fine or medium hair and want both volume and strength without sacrificing hair health, I'd definitely recommend giving this one a try.
