CONFESSION TIME: I’M incredibly picky when it comes to testing new beauty products. But in the oversaturated world of beauty releases, my skepticism benefits you because I know firsthand what it’s like to spend your hard-earned money on hyped-up products. As our beauty editor, I test hundreds of new launches each year, but Joico Defy Damage Detox Shampoo remains my holy-grail shampoo. Even when testing other items for work, I always compare them to Joico because it consistently outperforms both drugstore staples and pricier alternatives. Here’s why it’s a standout part of my routine for the past year:

What I Like

Impressive Ingredients

Effective ingredients, like a chelating agent and activated charcoal, remove product buildup and hard water deposits. According to double-board-certified dermatologist Dr. Brendan Camp, MD,chelating shampoo like Joico removes metal buildup from inside the hair shaft and mineral buildup that has accumulated over time. So if you’re a swimmer like me or have dyed strands, this is a must-have for you because it leaves my hair super clean, bouncy, and hydrated.

While these ingredients do an excellent job of detoxing my hair and scalp, Joico also contains moringa oil to help prevent overstripping my strands when used once a week. Just be sure to follow up with the matching Defy Damage conditioner and hair mask to help further soften and protect your strands.

It’s Compatible With All Hair Types

Joico genuinely works on all hair types, ranging from straight to coily. No, really. My mom has naturally straight, highlighted hair, while my strands are tighter curls in the front and coils in the back. We’re both huge fans of Joico. She finds the color-safe shampoo helps prolong her balayage, while the cleansing agents remove the hard water from her shower. For my hair type, it shines the most when removing excess product buildup, oil, and flakes without leaving my hair brittle. Gentle on the scalp and hair, it’s truly worth the investment, whether your hair is similar to ours or somewhere in between.

A Little Goes a Long Way

The quality of this shampoo truly shines. It’s highly concentrated, so I only need a dime-sized amount of shampoo for my mid-length hair. A 10.1 fl. oz bottle lasted me about eight months with use once or twice a week before I needed to repurchase. The slate grey shampoo has a creamy consistency that lathers into a rich foam, unlike cheaper alternatives. I can get a satisfying salon-fresh feeling while it removes hard water minerals.

What I Don’t Like

So this detox shampoo is excellent all-around. However, Joico recommends using it only once a week, which isn’t exactly realistic for me in the summer, when I like to swim as often as possible. Increasing the frequency leaves my hair a tad dry.

My hack is to spritz my hair with a leave-in conditioner before jumping into the pool. After shampooing, I leave the Defy Damage conditioner on for a few minutes, then follow up with the matching hair mask. If I’m feeling extra self-indulgent, I’ll pop on a shower cap, crank up the heat on my Dyson Supersonic hairdryer, and let its powerful airflow help the mask penetrate deeper. It’s a few extra steps that take 15 minutes but pay off by keeping my natural hair healthy and soft.

The Bottom Line: Is the Joico Defy Damage Detox Shampoo Worth It?

If you have color-treated strands or swim in the summer, consider investing in this Joico shampoo. It’s compatible with all hair types and works if you live in an area with hard water that leaves mineral buildup—like calcium and magnesium—that damages your tresses. These ingredients typically leave my tresses dry, frizzy, and brittle, so removing them with Defy Damage Detox Shampoo is especially helpful since I don’t own a showerhead filter.

Best for Volume

I’ve used this shampoo on and off for years, and the formula remains excellent. It contains a honey-derived conditioner for ample hydration, softening brittle strands, and a detangling agent—making Design Essentials an MVP on wash day.

I also can’t get enough of Ouai, the hair care line by celebrity hairstylist Jen Atkin. This shampoo uses chia seed oil to help create a bouncy, voluminous effect without overstripping my strands. Meanwhile, biotin minimizes breakage and hydrolyzed keratin to smooth and boost shine.

Best for an Itchy Scalp

Nizoral Anti-Dandruff Shampoo

Dealing with an influx of white flakes on your clothing? Same here, especially in the summer when I wear a baseball cap during outdoor workouts. I opt for this drugstore shampoo since it contains 1% ketoconazole, an ingredient found in prescription anti-dandruff shampoos. It helps treat fungus or yeast that causes dandruff, making Nizoral a must-have for reducing embarrassing flakes and soothing scalp irritation.
