San Diego Hair Extensions Boutique Del Mar is a hair extensions specialist at 1555 Camino Del Mar #203, Del Mar, CA 92014, inside the Salon Republic building at the Del Mar Plaza. The boutique focuses on hair extension installation, replacement, and maintenance, positioning itself as a dedicated extensions destination rather than a general-purpose salon. Customer service is available seven days a week by phone or text at (858) 205-0801, with appointment hours running as early as 6 AM on Fridays and Saturdays and extending until 9 PM most days. The studio is LGBTQ+-friendly and designated as a transgender-safe space, and it welcomes kids. Complimentary beverages are offered during appointments, and the suite includes Wi-Fi, wheelchair accessibility, and free parking in the plaza garage. Salt & Sand Lash Boutique operates out of Suite #10 in the same building, so clients can pair new extensions with a fresh set of lashes in a single trip. Booking in advance is required, and consultations are available for first-time clients deciding on extension type, length, and color match. Sunday hours are limited to 9 AM through 4 PM. Grabbing a post-appointment bite is effortless when Pacifica Breeze Cafe is right inside the Del Mar Plaza complex.
