Great product
a day ago
I have really super fine hair and I’ve used this product a couple of times and I can already tell a huge difference in how my hair looks and feels. I’m entering my 50s and my hair seems to be getting thinner so this product has really helped bring the life back into my hair.

I received this free for my thoughts. This has a nice thick texture that has a really nice lather that smells nice. With the first use, I could feel that my thin strands felt a little thicker with less breakage and frizz.

Does not weigh your hair down
a day ago
Product was received as part of an educational promotion - Incentivized. The consistency is thin enough to do the job of shampooing my hair, ridding my scalp of the residual products, the first time without multiple washing. It left my hair feeling very soft and clean. It cleans my hair without weighing it down or stripping it of my natural oils. I have yet to find a shampoo that combats the dryness of my hair and the fine texture simultaneously. I use a lot of products to lift my hair, providing texture and volume. That includes gels, texturizers, volumizers and the like. This builds up the hair texture, giving it a sticky and tacky residue that is hard to get rid of. That is until I found Olaplex shampoo. It just cleaned my hair, going down to the roots of the hair leaving it clean.

Best shampoo I've ever used

I've used Olaplex products for 2 years and my hair has never looked better. They may seem costly but they are very concentrated so you use very little product.

Incredible breakage control, and shine.

Even though this was an incentivized review, I can honestly say I was floored by the results. After just one use, my hair felt dramatically stronger—dryness and brittle breakage came to an almost complete halt. My hair looked shinier, healthier, and fuller, and I started getting compliments at work, which hasn’t happened in a long time. It also gave my fine hair volume without weighing it down, and the clean, fresh scent is a bonus. Highly recommend this for anyone looking for serious breakage repair and beautiful shine!

I’ve been using the Olaplex Nº4 shampoo for fine hair, and honestly, it’s one of the best shampoos I’ve tried! From the very first wash, I could feel a difference in how clean and refreshed my hair felt — but without that dry or squeaky feeling. It lathers beautifully even with a small amount, and it doesn’t weigh my hair down at all, which is super important for fine strands.
Over the past few days, my hair has felt stronger, softer, and looks visibly shinier. I’ve noticed less breakage when I brush, and it even helped reduce frizz, which is always a win. It also has a light, pleasant scent that makes washing my hair feel like a treat. I feel like it preps my hair perfectly for the conditioner. Definitely a new favorite in my routine!

Since I started using this Strengthening and Volumizing Shampoo from Olaplex, I’ve noticed BIG changes in my hair quality! It styles better, and also feels fuller. Definitely more manageable, with tons of shine! It looks gorgeous when I straighten it, very sleek and I appreciate the scent of the shampoo as well! It’s not an overpowering scent, more subtle I’d say. My hair feels stronger from root tip! My absolute favorite thing about this shampoo is that it doesn’t weigh my hair down! I have super fine hair, it gets tangled so easily! And I have a lot of hair too, to my waist to be exact! This shampoo literally is maintenance in a bottle! With hair to my waist, you can imagine how it is to maintain it! Finding a shampoo that not only nourishes my hair, adds shine, and strengthens it, And all without weighing it down is almost too good to be true! I love this shampoo and all it has to offer! All the fine hair girlies need to get you some #4 Bond maintenance, strengthening and volumizing shampoo from Olaplex like today! Don’t sleep on Olaplex & and all the hair care essentials! I’m quite literally sold, cuz girl!, my hair is hair’ing! I Highly recommend! I received this product complimentary, in exchange for my honest review.
