Threshold — Studio by Evelyn is a boutique hair salon in Kettering, Ohio, founded by stylist Evelyn, who has spent 5 years perfecting her craft in her adopted hometown of Dayton. Specializing in custom highlights, balayage, color, cuts, and treatments, Threshold is built on a philosophy of healthy hair first — every service is tailored to your goals without compromising hair integrity. Evelyn uses only two carefully chosen, family-owned professional brands — Keune and Maria Nila — selected for their ability to transform hair without damage.
