10 Best shampoos 2026 in the United States

Head & Shoulders Dandruff Shampoo is a well-regarded choice for those dealing with dandruff, especially for individuals looking to maintain a healthy scalp. Its clinically proven formula promises up to 100% protection against visible flakes with regular use, making it effective for many users. As America's #1 dandruff shampoo brand, it carries a strong reputation, which can be reassuring for first-time buyers or anyone struggling with scalp issues.

The shampoo is suitable for all hair types, which is a plus, as it simplifies selection for diverse consumers. The fresh green apple scent is an enjoyable feature, providing a pleasant bathing experience. Additionally, being paraben-free makes it a safer option for those concerned about harmful ingredients in their hair products. While the formula is effective for dandruff, some users may find it a bit harsh if they have very sensitive or dry scalps. The shampoo is designed for regular use, but frequent application could potentially lead to dryness for some individuals.

Head & Shoulders 2-in-1 Classic Clean Anti-Dandruff Shampoo & Conditioner is designed to cater to those struggling with dandruff issues. One of its notable strengths is its clinically proven formula providing 72-hour dandruff protection, making it very effective for frequent dandruff sufferers.

Additionally, being a 2-in-1 product, it simplifies the hair care routine by combining shampoo and conditioner, which is convenient for users who prefer a quicker hair care process. It's also paraben-free and safe for color-treated hair, which is beneficial for users concerned about harsh chemicals and maintaining their hair color. The fresh scent is an added bonus, ensuring hair smells clean and refreshed.

However, while it is suitable for all hair types, its primary focus is dandruff treatment, so users without dandruff might not see significant benefits. The inclusion of conditioning properties might not be enough for those with particularly dry or damaged hair who may need a more intensive conditioner. Nevertheless, its reputation as America's #1 dandruff shampoo brand and the trust of millions underline its effectiveness for its intended purpose.

The Biolage Color Last Shampoo is designed specifically for color-treated hair but can also be used on natural hair. Its key selling point is its ability to help protect and maintain vibrant hair color, making it an excellent choice for those who frequently dye their hair.

This shampoo features a low pH formula that gently cleanses the hair without stripping away its color, which is particularly beneficial for maintaining the depth, tone, and shine of color-treated hair for up to nine weeks when used as part of the complete Color Last system. It's also paraben and silicone-free, making it a good option for those looking for a more natural hair care product.

Additionally, it's vegan and cruelty-free, appealing to environmentally conscious consumers. The shampoo is suitable for adults and is scented with Biolage AromaScience™ fragrance, which adds a pleasant aroma to the hair-washing experience. The Biolage Color Last Shampoo is ideal for those with color-treated hair looking to maintain their hair's vibrancy and shine while also preferring a product free from harsh chemicals.
