10 Best shampoos 2025 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.

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.

The Biolage Hydra Source Shampoo is designed specifically for dry hair, making it a good choice if your hair feels rough, dull, or thirsty for moisture. It gently cleanses without harsh sulfates, which helps prevent stripping natural oils, an important factor if you have a sensitive or dry scalp. The formula includes fermented aloe and micro-filtered hyaluronic acid, both known for their hydrating properties, aiming to restore softness and shine while reducing frizz.

This shampoo is vegan and free from parabens, which is a plus if you prefer cleaner, plant-based ingredients. It's best used regularly to maintain moisture balance but is gentle enough for everyday use. However, if you have oily or fine hair, this shampoo might feel a bit heavy or weigh your hair down. Also, while it’s formulated to be mild, those with very sensitive scalps should patch test first to ensure no irritation occurs.

It is well suited for adults looking to nourish dry hair with a moisturizing shampoo that adds softness and gloss without harsh chemicals.
