Experts Say Expensive Shampoos Aren’t Necessarily Better

Consumers facing social media marketing for premium hair care products receive a clear message from dermatologists: affordable shampoos work as well as expensive ones, with effectiveness depending more on hair type and washing routine than price tag. “Instead of spending hundreds of dollars thinking, ‘If I just find the right shampoo, right conditioner, all of my troubles will go away,’ you also have to just look at what your process looks like … because that will often do the trick,” said Dr. Crystal Aguh, dermatologist and director of the Ethnic Skin Program at Johns Hopkins School of Medicine. Aguh categorizes people into two hair types: damage-prone and damage-resistant. Damage-prone includes those with very curly hair, people who chemically treat their hair, and those who use hot tools. Damage-resistant attributes include oily hair and straight hair. For curly or dyed hair, Aguh recommends washing less frequently to avoid removing too much sebum, a natural oil that coats and protects hair. People with tightly curled or coily hair should only wash their hair once a week, she said. Those with wavy, dyed hair might find it best to wash every two to three days. Damage-resistant hair that is oily and straight can be washed every day. Sodium lauryl sulfate, a common ingredient in many shampoos, should be avoided by people with damage-prone hair, Aguh advised. The chemical removes a lot of sebum, potentially leaving hair very dry and prone to breakage. Dr. Joe Tung, a dermatologist at the University of Pittsburgh Medical Center, echoed the sentiment that shampoo is skincare for the scalp, not just a cosmetic product. “Hair itself is biologically inactive once it grows out, but underneath the surface of the skin on the scalp is a full ecosystem with stem cells, immune cells, oil glands, nerve endings,” he explained. “When that ecosystem is balanced, the scalp feels comfortable and hair grows optimally; when it is disrupted, people can experience itching, flaking, excess oil, or hair loss.” Tung said people should consider what their scalp needs when choosing shampoo, while conditioner should be chosen based on hair texture and damage level. Dandruff and itchiness benefit from shampoos that address inflammation and microbial imbalance, whereas dry or chemically treated hair could benefit from a gentle cleanser with a rich conditioner. Both dermatologists emphasized that expensive shampoos and conditioners can work well, but affordable products often perform just as effectively. The key is active ingredients rather than branding. “An antifungal ingredient works because of its molecular activity, not because it comes in a luxury bottle or from a prestigious brand,” Tung said. Some luxury products contain fragrances or botanical extracts that can irritate sensitive skin, Tung noted. Simpler formulas are often better tolerated. Expensive shampoos typically rely on more refined conditioning agents and soothing ingredients that may make frequent hair washing more comfortable. Cost differences often reflect production factors rather than quality. “Some common brands are more affordable because they are made by large corporations that can achieve economies of scale,” Aguh said. “Sometimes expensive brands have a smaller team and lack the workforce and resources to reach those same cost advantages.” For consumers interested in sustainability, organic shampoos and conditioners offer an alternative. Monique Mason, owner of MOKO Organic Beauty Studio in Philadelphia, stocks organic products priced from $24 to $45. “Ingredients are the biggest of many factors influencing price,” Mason said. Organic products typically avoid inexpensive sulfates, synthetic fragrances, and parabens widely used in the personal care industry. Mason researches how the brands she sells manufacture their products to ensure their sustainability claims can be verified. “I get to know them, whether they’re family-owned, how they farm, how they source their ingredients,” she explained. The dermatologists’ consensus is clear: shampoo choice matters less than understanding your hair and scalp needs, maintaining a healthy washing routine, and not falling for marketing hype. Whether from a drugstore or a luxury boutique, the right product is the one that works for your specific biology—not the one with the highest price tag or prettiest packaging.
