The Thickening Treatment That “Grew Back” Sharon Stone’s Lost Hair Is on Rare Sale

As a beauty editor, I’ve heard every complaint and compliment you could think of. But the one thing I’ve never heard anyone say is that their hair is thick enough, luscious enough, or doesn’t shed at all (all of which would be a dream!). It’s one of the seemingly few universal beauty qualms. From DIY remedies to professional treatments, there are thousands of options, but one that seems especially promising is Augustinus Bader’s The Leave-In Treatment, which is currently on rare sale at Dermstore with the code CHEERS.

The very luxe and expensive brand came out of the gates with a laundry list of celebrity fans, especially for its The Cream moisturizer. But Sharon Stone is a fan of its (relatively) under-the-radar hair care line after she told Byrdie that The Leave-In Treatment (alongside The Shampoo and The Conditioner) “grew back” the hair she had lost following a stroke.

The hero ingredient of The Leave-In Treatment’s formula is the crux of the entire brand; it’s a proprietary innovation called TFC8 that can supposedly hone in on, address, and heal your hair’s individual and unique issues. There’s also anti-inflammatory neem extract that improves follicle health and prevents hair loss. Castor oil makes an appearance, too—a smart inclusion considering it stimulates blood circulation, which can speed up hair growth.

As for the shopper consensus? The most common rating is five stars. One reviewer said their “over processed hair… stopped shedding” after using this. Plus, “it makes hair so shiny and moisturized,” they said. And although expensive, it lasts a long time because you “don’t need very much” to cover your strands.

Another reviewer on the Augustinus Bader website said they noticed “thicker” hair after using The Leave-In Treatment just three times. A final reviewer called this a “game changer” that improved their hair length and stopped it from “coming out in clumps.”
