A practice, not a salon.

We do not sell appointments. We sell hours of attention.

One designer, one guest, one hour — kept private, kept slow.

Sigma began as a single chair in a Williamsburg loft. Seven years later we hold four, by appointment only. Each booking is a private sitting. There is no second hand to be done in the corner, no walk-in to interrupt the conversation.

We work in the Russian dry technique — no soaking, no nipping that shouldn't be done. The finish is sculpted, glazed, and engineered to hold for three weeks.

What we do, simply.

Pricing is fixed. Add-ons are honest. Designers may quote a small variance for custom art.

Four hands, four signatures.

Each designer keeps a waitlist. New guests are matched by Sora after a short note.

From guests.

Posted unedited. Three from the last two months.
The most considered hour I spend on myself. Sora reads what I want before I can describe it.

Russian manicure here is what changed my mind about nails entirely. Skin looks healed, not buffed.

My bridal trial felt like sitting for a portrait. Ari paints with a calmness I have not seen elsewhere.

Daily-ish. Mostly hands, occasionally the cat.

Brooklyn,
by appointment.

A quiet room above a bookshop. Coffee or tea. A chair that reclines.
