I’m not one to throw money at every shiny new hair product, but Olaplex No. 4 Bond Maintenance Shampoo has earned its spot in my shower.
This isn’t just another shampoo—it’s a game-changer for anyone battling dry, damaged, or frizzy hair.
Whether you’re dealing with color-treated locks or just want healthier, shinier strands, this cruelty-free, bond-repairing formula delivers.
It’s pricey, sure, but a little goes a long way, and the results? Worth every penny. Trust me, your hair will thank you.
My Journey with Olaplex No. 4: A Personal Experience
I’ll be honest—my hair and I have been through it. Years of coloring, from bold blondes to rich browns, left my fine, shoulder-length strands feeling like straw.
I’d cringe every time I ran a brush through, only to hear that awful snap of breaking hair.
My highlights were history, but even a gentler root touch-up every six weeks was enough to keep my hair fragile and flyaway-prone.
I needed something to bring it back to life, and that’s when my hairdresser introduced me to Olaplex No. 4 Bond Maintenance Shampoo.
The first time I used it, I was skeptical. The bottle’s sleek, minimalist design screamed “expensive,” and I braced myself for disappointment.
But the moment I worked a dime-sized amount into my wet hair, I was hooked. It lathered up like a dream—rich, foamy, and satisfying—without that squeaky-clean, stripped feeling I’d gotten from other shampoos.
The scent? Subtle, almost gingery, but clean and pleasant, not overpowering like some floral bombs I’ve tried.
After rinsing, my hair felt softer, like it was already starting to forgive me for years of chemical torture.
Over the next few weeks, I noticed real changes. My hair wasn’t just cleaner; it was stronger, smoother, and shinier.
The flyaways that used to haunt me in humid weather? Tamed. The breakage that left little hairs all over my sink?
Slashed. I started pairing it with Olaplex No. 5 Conditioner, and the duo was like a superhero team for my strands.
Even on days when I skipped heat styling, my hair had a natural bounce I hadn’t seen in years.
It wasn’t an overnight miracle, but by week six, I was getting compliments—something my brittle hair hadn’t earned in ages.
Now, I’m careful not to overuse it, but every wash feels like a mini spa day for my scalp.
What Makes Olaplex No. 4 Special?
You’re probably wondering what’s so magical about this shampoo. At its core, Olaplex No. 4 is built on the brand’s patented Bond Building Technology, featuring Bis-Aminopropyl Diglycol Dimaleate.
Sounds like a mouthful, I know, but this ingredient works on a molecular level to repair broken disulfide bonds in your hair.
These bonds get wrecked by coloring, heat styling, or even daily wear and tear, leaving your hair weak and prone to breakage.
By relinking them, Olaplex strengthens your strands from the inside out, making every wash a step toward healthier hair.
It’s also sulfate-free and color-safe, so it won’t strip your dye job or leave your scalp feeling parched.
The formula is highly concentrated, meaning you only need a tiny amount to get that luxurious lather.
It’s cruelty-free, too, which is a big win for those of us who care about ethical beauty.
Whether your hair is fine, curly, coily, or straight, this shampoo claims to work for all types, and from my experience, it lives up to that promise.
Maintenance Tips for Getting the Most Out of Olaplex No. 4
- Use a Small Amount and Emulsify: You don’t need to glob this shampoo on. Start with a dime-sized amount, rub it between your palms to emulsify, and then work it into your wet hair. This ensures even distribution and maximizes the lather without wasting product. If your hair is longer or thicker, add a bit more as needed, but don’t go overboard.
- Let It Sit for a Minute: Don’t rush the rinse. After massaging the shampoo into your scalp and strands, let it sit for about a minute. This gives the bond-repairing ingredients time to work their magic, especially on damaged areas like your ends.
- Pair with Olaplex No. 5 Conditioner: For the full effect, follow up with Olaplex No. 5 Conditioner. Apply it from mid-lengths to ends, let it sit for three minutes, and rinse thoroughly. This duo amplifies the repair and hydration, leaving your hair silky and strong.
- Limit Heat Styling: Olaplex No. 4 can’t undo all the damage if you’re frying your hair daily with a flat iron. Try air-drying when possible or use a heat protectant like Olaplex No. 7 Bonding Oil if you must style. Cutting back on heat helped my hair recover faster.
- Wash Less Frequently: Overwashing can strip your hair, even with a gentle shampoo. I wash twice a week, which lets my natural oils nourish my strands while still benefiting from Olaplex’s repair. If you have oily hair, aim for every other day to avoid drying out your scalp.
My Results and Reflections
After three months of using Olaplex No. 4, my hair is in a better place than it’s been in years.
The breakage that used to plague me is down significantly—my brush is no longer a graveyard of snapped strands.
My hair feels thicker, not in a fake, coated way, but like it’s genuinely stronger from within.
The shine is another big win; even on days when I air-dry, my strands catch the light in a way they never did before.
Frizz is still a battle, especially in humid weather, but it’s much more manageable, and my ends look less frazzled.
That said, it’s not a cure-all. My ends still need regular trims, and I’ve learned that Olaplex works best as part of a system.
Using it with No. 5 Conditioner and occasionally No. 3 Hair Perfector has amplified the results, but it’s meant rethinking my budget.
I’ve also had to adjust my washing habits—less frequent washes and minimal heat styling have helped the shampoo work its magic.
For me, the results outweigh the cost, but I get why some might hesitate.
If your hair is healthy, you might not need this level of repair, but for anyone with damaged strands, it’s a worthy splurge.
Pros and Cons of Olaplex No. 4 Bond Maintenance Shampoo
Pros:
- Strengthens and Repairs Damaged Hair: If your hair’s been through the wringer like mine, this shampoo is a lifesaver. The bond-repairing technology actually works, reducing breakage and making my strands feel stronger after just a few washes. After about two months, I noticed a 70% drop in those pesky broken hairs on my brush.
- Tames Frizz and Flyaways: Humidity used to be my hair’s worst enemy, with flyaways making me look like I’d stuck my finger in a socket. Olaplex No. 4 smooths things out, leaving my hair sleek and manageable, even on muggy days. It’s not a total frizz-killer, but it’s the best I’ve tried.
- Luxurious Lather with Minimal Product: A little goes a long way. I’m talking a coin-sized dollop for a full head of foamy, satisfying lather. This makes the high price tag sting a bit less, as one bottle lasts me months with weekly use.
- Color-Safe and Gentle: As someone who colors their hair regularly, I love that this shampoo doesn’t fade my medium brown dye. It’s gentle on my scalp, too—no itchiness or flaking, which I’ve struggled with using harsher formulas.
- Subtle, Pleasant Scent: The gingery, clean scent is a refreshing change from overpowering floral shampoos. It’s barely noticeable after rinsing, so it won’t clash with your perfume or styling products.
Cons:
- Steep Price Tag: Let’s not sugarcoat it—this stuff is expensive. At around $30 for 8.5 ounces, it’s a splurge compared to drugstore options. If you’re on a tight budget, it might feel like a luxury you can’t justify, even if it lasts a while.
- Not Ideal for Very Healthy Hair: If your hair is already in great shape, Olaplex No. 4 might be overkill. Too much protein can make healthy hair brittle, so you might not need its intense repair unless your strands are damaged.
- Requires Companion Products for Best Results: While the shampoo is great on its own, you’ll see the best results when paired with Olaplex No. 5 Conditioner or other products like No. 3 Hair Perfector. This can add to the cost and complexity of your routine.
- Subtle Scent May Disappoint: If you love a strong, lingering fragrance in your hair, the mild scent might let you down. I like it, but I’ve heard others wish it had more punch, like a minty or tropical vibe.

Olaplex No. 4 Vs. Other Shampoos
- Olaplex No. 4 Vs. Bumble and Bumble Bond-Building Repair Shampoo
I’ve tried Bumble and Bumble’s Bond-Building Repair Shampoo, and it’s a solid contender, but it doesn’t quite match Olaplex No. 4 for my needs.
Bumble and Bumble also focuses on bond repair with its proprietary blend, and it lathers beautifully, giving my hair a clean, bouncy feel. I noticed it added some resilience to my strands, especially after a few weeks of use.
However, it didn’t tackle frizz as effectively as Olaplex, and my ends still felt a bit parched after washing. Olaplex’s formula feels more nourishing, leaving my hair softer and shinier without weighing it down.
Bumble and Bumble is slightly cheaper, which is a plus, but I found myself using more product to get the same lather, so the cost evens out.
For color-treated, damaged hair like mine, Olaplex No. 4 edges out with its superior hydration and frizz control.
- Olaplex No. 4 Vs. Climaplex Strength and Volume Shampoo
Climaplex Strength and Volume Shampoo caught my eye because it promises both repair and volume, which is a big deal for my fine hair.
It uses bond-building ingredients similar to Olaplex and delivers a nice, foamy lather that makes my scalp feel squeaky clean.
I liked how it gave my roots a bit of lift, which Olaplex doesn’t do as well. But here’s the catch: Climaplex wasn’t as moisturizing, and my mid-lengths felt drier after a few washes.
It’s great for adding bounce, but it didn’t smooth out flyaways or reduce breakage as noticeably as Olaplex No. 4.
If your hair is less damaged and you’re after volume, Climaplex might be your pick. For me, Olaplex’s ability to repair and hydrate while keeping my hair manageable wins hands-down.
- Olaplex No. 4 Vs. Drugstore Sulfate-Free Shampoos
I used to be a drugstore shampoo loyalist, so I’ve tried plenty of sulfate-free options like L’Oréal EverPure or OGX.
These are budget-friendly and get the job done for basic cleansing, but they don’t hold a candle to Olaplex No. 4 when it comes to repair.
Drugstore shampoos often left my hair feeling clean but not nourished, and I’d notice more frizz and breakage over time.
Olaplex’s concentrated formula and bond-repairing tech make a tangible difference in strength and shine, something I never got from cheaper alternatives.
The downside is the price—drugstore brands are a fraction of the cost—but for damaged hair, Olaplex feels like an investment in long-term health.

Frequently Asked Questions (FAQs)
Yes, you can use Olaplex No. 4 daily if your hair needs it. It’s formulated for frequent use and is gentle enough not to strip your hair or scalp. That said, I find washing every other day or a couple of times a week works best for my fine, color-treated hair to avoid over-cleansing. If you have oily hair, daily use might be fine, but listen to your hair’s needs.
Olaplex No. 4 repairs broken bonds in your hair using its patented Bis-Aminopropyl Diglycol Dimaleate. It strengthens strands, reduces breakage, tames frizz, and adds shine while gently cleansing.

Olaplex No. 4 is designed for all hair types—straight, wavy, curly, or coily. Whether your hair is fine like mine, thick, or chemically treated, it works to repair damage and boost manageability.

For damaged hair, absolutely. The price stings, but the concentrated formula lasts ages, and the results—stronger, shinier, less frizzy hair—are undeniable for me. If your hair is healthy, you might not need it, but for anyone with breakage or dryness, it’s a game-changer. Try a mini size first if you’re on the fence.
