Dry shampoo: how to read the label and compare cans, powders and bars

Formats

• Aerosol: a pressurized can that sprays a fine mist. Check the safety statements on the can about flammability and use in ventilated places.
• Pump or non-aerosol spray: no propellant, usually with a different texture.
• Powder: a shaker you tap onto roots. It can be messy but is simple.
• Tinted versions: made for darker or lighter hair. Check the shade chart.

Reading the ingredient list

Dry shampoos list ingredients in order of amount. Common types include starches or clays, which are powders; alcohol; and fragrance. This page does not say what any ingredient does to hair or skin. It helps you see the label.

• Fragrance or parfum: a general term. If you avoid fragrance, look for fragrance-free, and check that the product does not use a masking scent.
• Allergen names: some regions require certain scent ingredients to be listed by name.
• Talc: some products list it, others do not. Read the list.
• Natural, clean, gentle: marketing terms. Check the ingredients.

Using the label

1. Read the directions and warnings on the package.
2. Keep away from eyes and follow the first aid statements.
3. Keep aerosols away from heat and flames, as the can says.
4. Ask a dermatologist or doctor if you have questions about your scalp or skin.

Our angle: cost per use

Containers are listed by volume or weight, so compare by unit price: price divided by ounces or grams. Then estimate how many uses a container gives you. A larger can with a low unit price is only a bargain if you finish it. Powders and bars can last differently from aerosols, and we do not state how many uses any product provides.

• Check size per can in multipacks.
• Travel sizes cost more per ounce.
• Compare fragrance-free and scented versions separately.
