Are expensive shampoos really worth the splurge?

Ornate bottles, glossy campaigns and persuasive testimonials often position premium shampoos as transformative fixes for every hair concern. But dermatologists say the reality is more measured: in many cases, affordable shampoos found in supermarkets and pharmacies can perform just as well as luxury alternatives.

Do premium shampoos outperform affordable favourites?

The key, experts explain, lies less in branding and more in ingredients, scalp needs and overall haircare habits. Understanding your hair type, frequency of washing and styling practices can make a greater difference than upgrading to a higher price point.

Dr Crystal Aguh, dermatologist and director of the Ethnic Skin Program at Johns Hopkins School of Medicine, categorises hair broadly into two groups: damage-prone and damage-resistant.

Damage-prone hair includes tightly curled or coily textures, chemically treated strands and hair frequently styled with hot tools. Damage-resistant hair typically refers to straight, oily hair types that tolerate more frequent washing.

For those in the damage-prone category, Aguh advises caution with shampoos where sodium lauryl sulfate is a primary ingredient. This cleansing agent removes sebum — the natural oil that coats and protects hair — which can leave strands feeling dry and more susceptible to breakage. She recommends washing tightly curled or coily hair once a week, while dyed wavy hair may benefit from cleansing every two to three days. Oily, straight hair, by contrast, can usually be washed daily without significant harm.

Aguh emphasises that “it’s not the products, it’s the process” that most affects hair health. Overwashing, frequent colouring and excessive heat styling can compromise hair regardless of how expensive a shampoo may be. She encourages patients to focus on technique and consistency rather than assuming a higher price guarantees better results. Mixing high-end and mass-market products is perfectly acceptable, she adds.

Cost differences often reflect business scale. Larger corporations can manufacture at volume and lower prices, while smaller brands may lack the infrastructure to achieve the same efficiencies. In some cases, premium products also incorporate costlier active ingredients or invest in organic sourcing and sustainable packaging.

Dr Joe Tung, dermatologist at University of Pittsburgh Medical Center, suggests reframing shampoo as skincare for the scalp. While hair fibres themselves are biologically inactive once they emerge, the scalp contains oil glands, immune cells and stem cells that influence comfort and hair growth.

“When that ecosystem is balanced, the scalp feels comfortable and hair grows optimally,” he explains. Disruption can lead to itching, flaking, excess oil or even hair loss.

Tung advises selecting shampoo based on scalp concerns — such as dandruff or inflammation — and choosing conditioner according to hair texture and damage level. Active ingredients, not packaging, determine efficacy. An antifungal compound, for example, works because of its molecular action, not because it sits in a luxury bottle.

Premium shampoos may contain refined conditioning agents that make frequent washing more comfortable. However, added fragrances and botanical extracts in some luxury formulas can irritate sensitive skin. Simpler formulations are often better tolerated.

Sustainability can also influence price. Monique Mason, owner of MOKO Organic Beauty Studio in Philadelphia, says organic products often avoid inexpensive sulfates, synthetic fragrances and parabens. Smaller, family-owned brands may also invest more heavily in traceable sourcing and environmentally conscious manufacturing.

Ultimately, experts agree that price alone is not a reliable indicator of performance. Choosing the right shampoo requires understanding your scalp, hair type and routine — and, when concerns persist, consulting a medical professional.
