Drugstore shampoos are popular again, but are they better? We asked experts.

If it seems like there's been a resurgence of beloved drugstore shampoos, there has been, just ask TikTok. If you search "drugstore shampoos" on the social media platform, you'll see tons of videos (with hundreds of thousands of views) showing that these affordable brands have revived their hair with softness and shine. And that's not all, the rise in search for drugstore shampoo reached an all-time high in the past 90 days on Google Trends.

And we must say drugstore shampoos have come a long way since the '90s and early '00s. If you've been looking for ways to cut down on budget, your hair care could be a place to start. That's why we tapped the experts to explain the differences and if a good old-fashioned drugstore shampoo will deliver the same results as its much pricier counterpart. While most of the experts agree some have a difference in formulation, the real question is: Is one better than the other?

Experts tell us the main difference between drugstore and salon shampoo is the quality and use of active ingredients for certain hair concerns. Cosmetic chemist and BeautyStat founder Ron Robinson, says the main differential factor is that many salon brands have patented and proprietary technology. However, he notes that "drugstore brands are quickly catching up" in that area. For example, L'Oreal has launched an entire bonding system in recent years.

Going further into the ingredient quality, cosmetic chemist Esther Olu explains that while both types of shampoos "fundamentally have similar ingredients," some salon quality brands may use milder surfactants aka cleaning agents. However, she explains that doesn't mean they will clean or perform better.

"Drugstore shampoos are formulated for mass production and affordability, while luxury brands focus on branding, sensorial experience and perceived exclusivity," says Olu. "Overall, I wouldn't say there is a huge difference between them. The effectiveness of a shampoo depends on the formula's surfactants, conditioning agents, and compatibility with an individual's hair type rather than the price tag."

When it comes to picking out the right formula, hairstylists say the biggest thing to take into consideration is your hair type and whether if it's color-treated or not. "If your hair is damaged and needs to be strengthened, I would suggest looking for ingredients such as keratin and amino acid," says celebrity hairstylist Marc Ballance. "For dry hair that needs moisture, check for products that include ingredients like glycerin and some oils like coconut, etc."

Celebrity hairstylist Angela Calisti adds some more healthy and hair-friendly ingredients to look out for such as hyaluronic acid as a hydrating agent and amino acids for bond repair. She also shares ingredients you should dodge: "Avoid sulfates if you want to maintain healthy hair, prevent dryness, and preserve color or treatments such as hair botox or hair keratin," says Cailisti. "It can strip moisture from your hair or fade color-treated hair faster and clog pores."

However, you don't want to swear off sulfates entirely says New York-based hairstylist Megan Robinson, she explains you'll just want to avoid Sodium Laurel Sulfate, which is a chemical sulfate that can be irritating for dry scalps. "Don't be scared of a sulfate -- just make sure it's plant-derived!" she explains. "Sulfates are what make shampoo foam. Look for ALS (ammonium lauryl sulfate), derived from coconuts. This will provide a luxurious clean without stripping or causing irritation."

With that being said, Olu will always recommend patch testing first. "Ultimately, the best approach is to find what works for your specific hair needs rather than strictly avoiding ingredients based on trends and/or misinformation," she explains.
