Hiusseerumia

Hiusseerumia is a Finnish term that translates to "hair serum." It refers to a cosmetic product applied to the hair, typically after washing and conditioning, to improve its appearance and manageability. Hair serums are formulated with various ingredients, including silicones, oils, and vitamins, which coat the hair shaft. This coating can help to reduce frizz, add shine, detangle strands, and protect hair from heat styling and environmental damage.

The primary functions of hair serum include smoothing the hair cuticle, which is responsible for shine and preventing frizz. Silicones are common ingredients that create a protective barrier, reflecting light and making hair appear smoother and glossier. Other ingredients like argan oil, coconut oil, or jojoba oil can provide moisture and nourishment, leaving hair feeling softer. Many serums also offer heat protection, forming a shield that helps prevent damage from blow dryers, straighteners, and curling irons.

Application of hair serum usually involves dispensing a small amount onto the palms and then distributing it evenly through damp or dry hair, focusing on the mid-lengths and ends. It is generally not recommended to apply serum directly to the scalp, as this can lead to greasiness. The specific benefits and ingredients vary widely among different products, catering to diverse hair types and concerns, such as dry, damaged, color-treated, or fine hair.
