Sissi M. - Founder, Ongi

Sissi Marie has spent over two decades engaged in the intimate work of transformation that takes place strand by strand, in the space between a client and her reflection. 

Trained as a full Cosmetologist, Sissi’s foundation is rooted in holistic beauty, considering the skin, scalp, and the body’s relationship to beauty. This holistic lens shapes everything she does at Ongi, from the way she assesses a scalp for optimal scalp health before a single snip, to the meticulous care she takes in selecting every product that enters the studio.

Her specialty lies in connection-whether through the scalp, the body, or color. Specifically, her gift is in the art of reading hair's history and returning it to its most luminous, intentional state. Whether working through years of damage with corrective color, guiding a client in her first sacred gray transition, or building dimension through the Obangsaek color philosophy, Sissi approaches every service as a ceremony rather than just a transaction.

Certified in Korean Hygee Scalp Massage, she brings rare technical precision to improving scalp health, treating the root as the foundation for everything that sprouts from it. For clients who desire their time in the chair to extend beyond the physical, she weaves in gentle attunements—creating a quiet recalibration of energy alongside the transformation of form.

At Ongi, Sissi has crafted something truly special: a studio where slowing down is the practice, where intention carries weight, and where your hair is examined before it is touched. The outcome is never ‘just’ a beautiful result, but a comprehensive beautiful experience of becoming.

To Sissi, every ritual is personal. Every client is a ceremony.
