As Gen Z TikTok creators challenge beauty norms with “propaganda I’m not falling for” videos, one question keeps bubbling up in comment sections: Is expensive shampoo really worth the price—or is drugstore shampoo just as good? In an age of budget-conscious beauty and viral Pantene shoutouts, the debate between prestige vs. practicality is gaining traction.
So, is that $10 bottle from the drugstore just as effective as the $40 luxury one? According to cosmetic chemists and hair experts, the answer may surprise you.
What Does Shampoo Actually Do?
Despite flashy marketing, the primary function of shampoo hasn’t changed: to clean your hair and scalp. And it’s not just about looking fresh. “Styling product buildup can clog follicles and slow hair growth,” says David Adams, a certified trichologist and co-owner of FourteenJay Salon. “Removing that gunk is essential for stronger, thicker hair.”
A clean scalp also sets the stage for better styling and conditioning, making shampoo a critical first step in any hair care routine.
What’s Really in Your Shampoo?
Here’s a secret: most shampoos—regardless of price—share the same basic blueprint. According to cosmetic chemist Perry Romanowski, shampoo is about 80% water and 15% detergent, with the rest being conditioning agents, preservatives, and fragrance.
The detergents (often sulfates) are responsible for removing oil, dirt, and buildup. While sulfates like sodium lauryl sulfate have gotten a bad rap for being harsh, they aren’t inherently bad. “Sulfates are not the enemy—they’re just misunderstood,” says cosmetic chemist Krupa Koestline, founder of KKT Labs. Well-formulated shampoos balance cleansing agents with moisturizers to avoid stripping natural oils.
More expensive formulas may include fancy ingredients like peptides or biotech botanicals, but these often make up a tiny percentage of the overall formula and don’t always translate into dramatic results.
Why the Price Difference?
The truth is, a higher price doesn’t always mean better performance. Much of what you’re paying for in luxury shampoos is the branding, packaging, and marketing—sometimes up to 40% of the total cost.
Big beauty corporations like Unilever or P&G have massive R&D budgets and can afford to make high-quality, affordable products at scale. In many cases, their drugstore shampoos perform just as well—if not better—than boutique brands.
“There’s also a psychological component,” Romanowski notes. “Fragrance, packaging, and brand perception can influence how we think a product works.”
When It Might Be Worth Spending More
That said, some hair types or concerns can benefit from more tailored formulas. You might consider upgrading if:
You have frizz: Look for shampoos with low pH, humectants like glycerin, and anti-static agents.
You need volume: Choose lightweight, protein-rich formulas with minimal conditioners.
You have color-treated hair: Look for UV filters and gentle surfactants. But remember, water is the real culprit behind color fading.
You have a sensitive scalp: Seek out formulas with minimal fragrance and no harsh preservatives—but be ready to test a few.
Even then, some of the best options for these concerns are available in drugstores.
Final Verdict: Save or Splurge?
You don’t need to spend big to get clean, healthy hair. A $10 shampoo can deliver excellent results if it’s well-formulated and suits your hair needs.
That said, if you love the scent, packaging, or feel of a luxury product, there’s no harm in the occasional splurge. Just know that great hair doesn’t come from price tags alone.
“Shampoo is a starting point,” Adams says. “But healthy habits—like limiting heat styling, avoiding rough towel drying, and using the right tools—matter just as much.”
A good shampoo doesn’t have to be expensive. The best formula is the one that works for your hair type, fits your budget, and makes you feel confident. Everything else? Marketing.
