Shampoo vs. Conditioner: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on December 28, 2023
Shampoo is a hair care product designed to clean the scalp and hair, removing dirt and oil, while conditioner is used after shampooing to moisturize, detangle, and improve the manageability of hair.

Key Differences

Shampoo is primarily formulated to cleanse the scalp and hair, removing sweat, oil, dirt, and environmental pollutants. Conditioner, in contrast, is designed to restore moisture, enhance hair's texture, and smooth the hair cuticles.
Shampoo is applied to wet hair and worked into a lather to clean, and then rinsed out. Conditioner is applied mainly to the lengths of the hair, not the scalp, and it works by smoothing and detangling hair fibers.
Shampoos often contain surfactants and detergents to effectively cleanse. Conditioners are formulated with ingredients like oils, emollients, and silicones to moisturize and protect the hair.
Regular use of shampoo is essential for maintaining scalp hygiene, but overuse can strip hair of its natural oils. Using a conditioner helps to replenish moisture and protect hair from damage.
Both shampoo and conditioner come in various formulations to cater to different hair types and concerns, such as volumizing, moisturizing, or color-protecting.
