Women-owned Sia’s Eyebrow Threading in Point Loma has operated a walk-in threading studio at 1050 Rosecrans Street near Sunset Cliffs since 2016, building on a threading practice that dates to 2009. The service menu covers eyebrows, upper lip, chin, sideburns, and full-face threading in a single visit, using a cotton-thread technique that removes hair at the follicle without chemical contact — a precision method that pairs with the lash-lift and brow-lamination work at Aura by Ashley for clients building a full brow-and-lash routine. Threading pulls hair from the root without applying wax, cream, or chemical depilatory to the skin surface, making it the default method for clients managing rosacea, eczema, or retinoid sensitivity. Henna art services round out the studio’s offerings, adding temporary decorative body art as a second specialty that complements the brow-and-lash shaping at Glorious Lash & Brow PL nearby. Full-face threading sessions address every major facial zone — brows, forehead, cheeks, upper lip, chin, sideburns, and neck — in a single sitting without any skin-surface product application.
