Sunlight spills through Tei Salon's ornate, arched windows to illuminate stations where stylists work to restore each head of hair to a healthier texture and hue using nothing but their shears and keen aesthetic eyes. Well, not exactly nothing. The stylists also rely on a stock of haircare products from Bumble and bumble and L'Oréal Professional Series Expert, all of which are potent enough to nourish, smooth, and give hair the ability to swish over shoulders in cinematic slow motion. The salon, tucked within the Chestnut Village Shoppes, connects to its sister spa, where Tei Salon's Dermalogica-certified aesthetician focuses on curing skin of its every ill, from rejuvenating mature skin to purifying acned complexions to defuzzing bodies during specialized facials and a full complement of waxing services.
