Even when you’re not seeking it out, lavender has become hard to escape. A look around my own apartment revealed three bars of lavender bath soap; a lavender “relax” aromatherapy bar by Treestar; a vial of Ms. Wexstten’s Feel Good Potion; Sleep Well Therapy Balm by Scentered; Dr. Kerklaan Natural Sleep Cream with CBD extract and calming sensation citrus and lavender; a lavender-scented candle; a bouquet of dried lavender in a vase in the bathroom; and a small pillow stuffed with lavender to be placed under one’s nose at bedtime.

Many of these items are my wife’s. But lavender has entered the men’s grooming world too, in products like Jack Black post-shave cooling gel and overnight balm from the Art of Shaving. (And the bath soap was mine.)

Nature’s Chill Pill

If not a precious plant in modern times, lavender once carried the whiff of semi-luxury. If you stayed in a nice European hotel, your room had crisp linens scented with lavender. That bath soap would have been a special imported treat costing $15 a bar, not something I might have gotten at the corner CVS.

Lavender was a key ingredient in the bougie domestic fantasy sold by retailers like Williams Sonoma and L’Occitane en Provence. It wafted gently over the entire oeuvre of Peter Mayle, the author of “A Year in Provence,” among other books.

Now you can buy Downy Infusions Lavender Serenity fabric softener.

Linda G. Levy, the president of the Fragrance Foundation, an organization that promotes and supports the perfume industry, has noticed lavender as a highlighted ingredient in luxury fragrances like Libre, new from YSL, as well as popular perfumes like Ariana Grande’s Cloud, which features a top note of lavender and won the foundation’s fragrance of the year award this past June.

“Lavender is easy for consumers to translate,” Ms. Levy said. “It’s something they can understand without having to do a lot of research.”
