Game-Changer for My Hair!
I can’t say enough good things about this shampoo! I’ve been using it for a few weeks now, and the difference in my hair is incredible. It has transformed from dry, dull, and lifeless to shiny, smooth, and healthy-looking.The first thing I noticed was how gentle it is on my scalp—it lathers beautifully, and it has a pleasant, light fragrance that isn’t overpowering. After just the first wash, my hair felt softer and more hydrated, but over the course of the past few weeks, the changes have been dramatic.My hair feels significantly stronger and looks so much shinier without being greasy. I used to struggle with split ends and frizz, but now my hair feels nourished and less prone to breakage. It’s like I’ve had a mini hair revival. It’s so much easier to manage, and I can finally go a few extra days between washes without my hair looking flat or greasy.I’ve tried so many shampoos in the past that promised results but never delivered, but this one is the real deal. My hair feels healthier than it has in years, and I’m so happy I found it. Definitely a must-try if you’re looking to give your hair some love and restore its natural shine!

Fantastic Shampoo That Restores and Strengthens Hair
This Olaplex shampoo is one of the best hair products I have ever used. From the first washes, I noticed my hair felt softer, stronger, and much healthier. It really helps repair damage and leaves my hair smooth and shiny without weighing it down.The formula is gentle but very effective, and a little bit goes a long way, so the bottle lasts longer than expected. I also appreciate that it doesn’t have a strong or unpleasant scent, and it works well even on color-treated hair.Overall, this shampoo is worth every penny. It has truly improved the look and feel of my hair, and I highly recommend it to anyone who wants healthier, stronger, and more beautiful hair.

Love this shampoo!
This is pretty much the best shampoo you can get. My stylist recommends this shampoo only, and it’s awesome for my hair, which has to be chemically straightened due to its extreme frizzyness. I follow up with “It’s a 10” leave-in conditioner (“miracle leave-in product”). Perfect combo.

Clean, Soft & Strong Hair Every Wash! 💆♀️✨
This Olaplex No. 4 Bond Maintenance Shampoo is legit — it cleans my hair really well without stripping moisture, and leaves it feeling noticeably softer and stronger after each wash. It lathers nicely and rinses out easily, and over time I’ve seen way less breakage and frizz. Perfect if you’re coloring or heat‑styling often and want a shampoo that helps repair and protect your strands. Great everyday pick that actually makes a difference! 🧴💧

Best product!
I have heavily treated hair. Been coloring, perm, bleach, hot irons, etc for past 35 yrs. My hair can be dry, and frizzy. Now my hair seems quenched, and healthy.I use this product every 2-3 days. One small bottle lasts for 13 months. My hair is thick, and past my shoulders. A dab size of a nickel, them emulsify it in your hands vigorously till it covers your hands in a layer of white creaminess. Apply to hair and you will notice how much it covers. I leave it in my hair for a good 10+ minutes while I shave. I never need to use conditioner when using this product. I do use a leave in spray conditioner after I towel dry. My hair has never been healthier.

Works great on frizz but does contain a lot of chemicals
I’ve been using Olaplex No. 4 Bond Maintenance Shampoo for a few months (based on the recommendation of my hair stylist), and the results have been great! It has completely eliminated frizz, leaving my hair soft, smooth, and with a beautiful shine. I don’t usually need to use a conditioner.That said, it’s worth noting that this shampoo does contain a LOT of ingredients, which might be a concern for some. Hence the 4 stars. Although upon further research I read ” OLAPLEX is colour-safe, vegan, PH balanced and completely free from cruelty, DEA, aldehydes, formaldehyde, silicone, parabens, sulphates, phosphates, gluten and nuts.” While it has worked wonders for my hair, those who prefer all-natural products might want to look elsewhere. I rotate it with a more natural shampoo.It’s also definitely on the pricey side, but a little goes a long way—you only need a very small amount so the bottle lasts much longer than expected. For me, the results have been worth every penny, and I’ll keep buying it. If you’re looking for a product that can tackle frizz and leave your hair looking its best, this one is worth trying!

Great shampoo highly recommended
Excellent shampoo for over processed hair. My hair stylist uses this shampoo in her salon. So I now use to maintain my hair. I color my hair every 8 weeks so this shampoo is a must. This shampoo will not strip your color. Also keeps my hair from drying out or feeling like straw. I highly recommend this product also I use the conditioner to add more softness and protection when applying products and blow drying my hair.

Das Olaplex 4 ist ein sehr angenehmes Shampoo, eine kleine Menge reicht, also wesentlich ergiebiger als andere Shampoos. Daher steht bei uns immer eine große Flasche mit Pumpdosierer in der Dusche. Wir hatten zuvor immer direkt bestellt, aber nach dem Preisvergleich bestellen wir nun hier.

So I’ve had this weird scalp condition where I shower with the most gentle of shampoos and most moisturizing of conditioners, my hair drys, and my scalp gets tight and itchy and then second day my hair is greasy and I have dandruff. Super weird. Been happening for the better part of two years, and have tried all the dandruff shampoos which made it a million times worse, then I tried all of the moisturizing shampoos and even the no poo-shampoos. Nothing worked.I decided to buy this shampoo because I had bleached half my hair from the ends to about the middle of my medium length, thin hair, and it was starting to look… Sad. Thought if this could at least fix some of the damage of the bleached parts, I’d be happy.This not only added moisture and shine and life to my hair, it completely fixed my scalp condition?! Like. If I had known it would moisturize my scalp without making it greasy, and completely stop the itching… I would have bought this years ago. It’s a small bottle, but you only need a little bit and … No more itching…. I’ll never buy anything else ever again. So impressed and happy. Also it smells great. Worth every penny.

Hands down, this is the best hair product on the market. The UAE water had damaged my hair making it fragile and snap easy ( snapping off by the handful every day). Even with a water filter, it still wasn’t enough. After spending thousands of dirhams on other various products trying to make my hair stronger, I should have started with Olaplex from the very beginning. It took around 3 treatments to feel significant strength return to my hair. There is now a normal amount of loss. Even my hairdresser noticed the difference (and she uses 1 and 2 as part of my colour treatment when I get my hair done). I use 0 and 3 together as well as Olaplex Shampoo and Conditioner. It’s a small price to pay for big results. Very happy with this purchase and can’t recommend this product enough. A personal recommendation from me to you 🫶
