Olaplex Nº. 4 Bond Maintenance Shampoo: Reduces Breakage & Strengthens Hair | Hydrates, Smooths & Detangles | For Coily, Curly, Straight, and Wavy, 1000 mL / 33.8 Fl Oz

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! 🧴💧

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.

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.

Was skeptical at first when I received. Seemed so tiny BUT a little goes a long way, amazing lather. I have medium length, wavy hair. My hair felt so soft, and so clean after shampooing. I think this bottle could last 5-6 months. I shampoo 2 times weakly. I'm sold!!°

Olaplex is a great! This is the genuine product and leaves my hair looking soft and shiny. the shipping was fast, only downside it that it is expensive but you get what you pay for!

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!

This is the holy grail of hair products. I am in my late 40s and have thin, dry, color damaged hair. My hair has been frizzy and I could only wear a ponytail and even in that it would become a tangled rat mess. I have tried 100s of dollars in products from Keratin hair treatments, Aveda products, Nexus, Pantene, Its a 10, blowouts EVERYTHING under the sun and nothing was working. I was ready to shave my head and start over. Then I found this and read soooo many reviews and said shoot all I have to lose is more money. So for my fine, thin, color/highlighted damaged hair I got the 4/5 shampoo and conditioner, weightless nourishing mask,#3 Bond building hair and the #9 Bond Protector. My hair is now SOOOFFFTTT, not frizzy even when it is humid out (I live in the desert) so not many humid days until recently. This is all in just 3 days!!! Day one I used the Shampoo and Hair mask with already noticeable difference, Day 2 and 3 I used only the shampoo and conditioner. I started with the small bottles at $30 each and I am so far very pleased and plan on once I run out getting the larger bottles. I will tell you that you need a very very small amount of shampoo, it goes a LONG ways. The conditioner maybe a nickel size amount as it also goes a long ways. When I first used this and was done rinsing my hair, it did not feel soft and I was thinking okay I am going to not have fun brushing my wet hair and it was going to be a waste of money. Boy I was fooled. even though my hair did not feel soft and slick after conditioning, the wet brush I use as always just glided thru my hair with such ease. I was like oh okay and then once I dried it I was completely shocked at the difference the first wash alone had made. There were no tangles and the entire day my hair has been smooth, soft and manageable! I say take your chance and get this product, I hope you are as happy as I am with this. I plan on tossing every other hair product away now that this is the only thing that genuinely works for my hair in a way that I have never experienced with a hair product before.

My hair looks so thick and shiny now! This product is worth its weight in gold!

I love olaplex, I always get compliments on my hair that it looks so healthy

Olaplex is perfect product range and I bought it because I had serious damage to my long hair. I bought this product and a couple of others from the range. My hair condition quickly improved. I think the at home treatments work out value for money compared to regular in salon treatments. I recommend Olaplex range especially when you have damaged or coloured/dry hair.

Mi esposa siempre usa esta marca, Le encantan se nota la buena calidad

Olaplex is the best in hair care. This shampoo is no different. It cleans thoroughly without leaving my hair dry, it has a pleasant smell, and nourishes at the same time.

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 🫶
