Excellent Shampoo
I was out of Olaplex shampoo and conditioner for about a month, maybe two, & noticed that my hair was unruly and falling out (splitting at the ends) faster than usual. I wash my hair daily and Olaplex is the only shampoo that I like to use since I wash it so frequently. My hair is now shiny and loo...

Low porosity/Coil/4C-ish hair girlies, stay AWAY!!
I will leave this review on all the products I used that caused HUGE CHUNKS of my hair to fall out on wash day after using them as instructed. I get a silk press about 2-3 times and year and before using their products my hair was mid-back length, thick, with voluminous layers. However, due to low...

Suds up beautifully
Hair Type Wavy Hair
I received Olaplex No.5 Bond Maintenance Shampoo for educational purposes in exchange for my honest review. The shampoo is very thick and concentrated, which I really appreciate. I have thick, curly hair and it instantly lathered up beautifully, the rich lather and suds make me feel like my hair is getting a deep clean. The scent is very light and almost unnoticeable, which I like, and after just one application my hair felt extremely clean. Unlike many other shampoos, this one left my hair feeling smooth, almost like I had used a conditioner. I also noticed an improvement in the look of my split ends, which is impressive considering how much my hair goes through with flat ironing and blow drying. I really love everything about Opaplex, but wish it was just a bit more cost effective. Overall, this is a product I will definitely purchase again and highly recommend to others.

I would like to try it always

Olaplex No. 4 Bond Maintenance shampoo
Hair Type Wavy Hair
As someone with an oily scalp and fine, easily tangled hair, I've tried countless shampoos that either stripped my hair or left it greasy within a day. Olaplex No. 4 has completely changed that. After just one week of use, I noticed a dramatic improvement: my hair, which typically became heavy with grease within two days, now stays soft, loose, and fresh until the next wash. The shampoo has a clean, pleasant scent—subtle enough not to overpower, yet refreshing during use. What truly sets it apart is how it treats fine strands: no matting, no tangling, just smooth, manageable hair straight out of the shower. It lathers beautifully and rinses clean without leaving residue or buildup. Olaplex's bond-building formula lives up to its reputation. My hair feels stronger, more resilient, and noticeably healthier with each wash. For anyone dealing with oily roots and delicate strands, this shampoo is a game-changer.

Great for color treated hair!
Hair Type Straight Hair
I received this product complimentary as part of a promotion, but all opinions are my own! I would definitely recommend this shampoo for anyone with color treated hair due to it's intense strengthening and repairing properties - it leaves my hair looking and feeling healthier! It adds moisture and shine while also leaving the hair smoother and with less frizz. It has nice simple packaging - it's clean and good for use in the shower! It's easy to dispense the product. It's $32 for 8.5oz which is on par with comparable brands. It smells nice and light - clean and fresh. It lathers well and are little bit of product goes a long way - I was pleasantly surprised at how little product I needed for my long, thick hair. Plus it left my hair very clean without stripping!

Underwhelmed
Hair Type Wavy Hair
Olaplex No. 4 Fine Bond Maintenance Shampoo is thick and when I applied it to my hair, it just concentrated on the area that I put the shampoo in. It does not do a great job distributing the product throughout the hair if not worked into a lather in your hands prior. I had to work it a little more than I'm used to, to make sure my entire hair was lathered. There were times where I had to apply more shampoo because it just wasn't enough to cover it. In my experience, it was easier to start to lather the shampoo in my hands, to a light lather, and then add it to my hair, making it easier to distribute the product evenly. It has a light fresh scent, doesn't linger and I cannot smell it throughout the day. With other products, there are some lingering scent but I did not get that with this product. It is not a shampoo that will cleanse your hair or scalp. "Received a s part of an educational promotion"
