Shampoo
Shampoo is a functional hair care product with one primary and essential purpose: to cleanse. Its job is to effectively remove excess oil, sweat, dead skin cells, product buildup, and environmental pollutants from both the scalp and the hair. Think of it as the foundational reset for your hair care routine, creating a clean slate that allows conditioners and styling products to work their best.
The cleansing power of shampoo comes from ingredients called surfactants. These molecules work by trapping oil and dirt, allowing them to be rinsed away with water. The type and concentration of these surfactants determine the shampoo’s strength, ranging from powerful clarifying formulas designed for a deep clean to gentle, sulfate-free options ideal for daily use on dry or color-treated hair.
The key to an effective wash is to focus the shampoo where it’s needed most: the scalp. This is where the majority of oil and buildup accumulate. Concentrate your application on the roots, massaging gently with your fingertips to cleanse the scalp thoroughly. The lather that rinses down the lengths of your hair is typically all that’s needed to clean them without causing unnecessary dryness. At sylvaia, we believe choosing the right shampoo for your scalp type is the first step to healthy hair.
