【Background of Implementation】

"for Style" is a new product series that enhances styling power in addition to LaSana's hair repair capabilities. The popular Korean K-POP girl group "SAY MY NAME" has been appointed as the muse.

This campaign was initiated from a shared desire between the brand and SAY MY NAME, born from their experiences as muses for for Style, to "create projects together with the fans." This project is a "co-creation project" where items are developed together with the fans. The fans' votes will shape actual merchandise, and those items will accompany someone's daily life – delivering an experience that allows them to feel the connection between the brand, SAY MY NAME, and the fans. The production process is scheduled to be released as video content.

【for Style Concept】

"for Style" is a new product series that enhances styling power in addition to LaSana's hair repair capabilities.

Enjoying your current hair as it is, and the beauty of your future self, both are important.

To always love yourself. Damage care and styling.

for Style Official Site: https://www.lasana.net/products/series-forstyle/

【Common Features of the for Style Series】

Focuses on protein bonds inside damaged hair. Adopts "Bond Hair Formula" (※3)

When hair is damaged by coloring, perms, or UV rays, the bonds that support the strength inside the hair loosen and do not return naturally. "for Style" not only provides styling function but also supports the loosened bonds, which was previously difficult. It repairs the inside of the hair and leads to its natural strength (※4).

For those who dislike oils. Three items to choose from based on your desired look.

For those who dislike the stickiness and unique scent of oils but want to try trendy styling. Enjoy wet hair and shiny hair without stickiness. You can choose the product that best suits your desired look.

Multi-protects hair and cares for damage.

Our surroundings are full of damage factors such as dry outdoor air, direct sunlight, and friction. It can be used on both dry and wet hair and cares for all types of damage, including "heat, humidity, dryness, UV rays, static electricity, friction, and pollutants."

"White Freesia Scent" with a transparent feel.

Contains two types of natural essential oils (※5): "Bergamot essential oil" and "Jasmine essential oil." It has a fresh and transparent scent with delicate freesia, leaving a gentle lingering scent of powdery musk and jasmine.
