Many shoppers ask whether expensive shampoos and conditioners deliver results that justify the higher price, and dermatologists interviewed by The Associated Press said the decision often comes down to ingredients and individual needs rather than branding.
The experts said affordable shampoo and conditioner products sold in grocery stores and pharmacies can do the job for many people, and they advised consumers to evaluate ingredient lists, their own scalp and hair concerns, and their broader hair-care routine. Some premium brands can work well, they said, including products with active ingredients that cost more to manufacture, but the effectiveness still hinges on what is inside the formula.
Dr. Crystal Aguh, a dermatologist and director of the Ethnic Skin Program at Johns Hopkins School of Medicine, said she generally categorizes people into two hair types: damage-prone and damage-resistant. She described damage-prone hair as including very curly hair, chemically treated hair, and people who use hot tools to style their hair. She said damage-resistant attributes include oily hair and straight hair.
For people with damage-prone hair, Aguh said they should avoid shampoos that have sodium lauryl sulfate as the main ingredient, because it removes a lot of sebum, a natural oil that coats and protects hair. Without sebum, she said, hair could feel very dry and break easily.
Aguh also tied wash frequency to hair type and treatment history. For curly or dyed hair, she recommended washing less frequently to avoid removing too much sebum, saying people with tightly curled or coily hair should wash their hair once a week. She said people with wavy hair that is dyed might find it best to wash every two to three days, while damage-resistant hair that is oily and straight can be washed every day.
Beyond product choice, Aguh emphasized routine over purchase decisions, telling patients that “it’s not the products, it’s the process” that affects hair health the most, including how often hair is washed, dyed or treated with heat. She said consumers do not need to buy an entire line of expensive products, and she added that it is fine to mix high-end and mass market items.
Another dermatologist, Dr. Joe Tung of the University of Pittsburgh Medical Center, said people should think of shampoo as skincare for the scalp, not just a cosmetic product. He described the scalp as having an ecosystem beneath the surface that includes stem cells, immune cells, oil glands and nerve endings, and he said disruption can lead people to experience itching, flaking, excess oil, or hair loss.
Tung said shampoo choice should start with what the scalp needs, and conditioner should be chosen based on hair texture and damage level. He said dandruff and itchiness benefit from shampoos that address inflammation and microbial imbalance, while dry or chemically treated hair could benefit from a gentle cleanser paired with a rich conditioner.
On the question of whether luxury products earn their cost, Tung said expensive shampoos and conditioners are sometimes worth the price, but effectiveness is determined by active ingredients and not 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. He added that expensive products typically use more refined conditioning agents and soothing ingredients that can make frequent washing more comfortable, but some luxury formulas include fragrances or botanical extracts that can irritate sensitive skin, and simpler formulas are often better tolerated.
The AP story also included input from retail and sustainability-focused shopping. MOKO Organic Beauty Studio in Philadelphia sells organic shampoos and conditioners that cost from $24 to $45, owner Monique Mason said, describing the salon’s mission as providing products that are good for scalps and “the planet.” Mason said ingredients are the biggest factor influencing price and said organic products typically avoid inexpensive sulfates, synthetic fragrances and parabens widely used in personal care products.
Mason said she researches how the brands she sells manufacture their products so sustainability claims can be verified, and she said she gets to know whether brands are family-owned, how they farm, and how they source their ingredients.
