TESTED FOR HORMONE SAFETY98% NEW BABY HAIRS¹

The first step for hair that's thinning as hormones shift.

 

Have you noticed a less defined hairline? More hair in the drain after every wash? When hormones shift, and estrogen falls in particular, hair spends less time growing and more time shedding. Density Shampoo is the first step of a routine made for exactly that.

 

Your hormones are already changing. Your hair care shouldn't add to it. Every formula is Tested for Hormone Safety.

 

A gentle shampoo with Capilia Longa, a turmeric stem cell extract that boosts hair density and thickness, and coconut-based cleansers that gently cleanse and nourish the scalp.

 

Through every stage

 

  • Perimenopause: when shedding first starts to pick up.

  • Menopause: when thinning starts to show.

  • Postmenopause: when hair grows back finer.

 

For the best results, use it with Density Conditioner and Density Drops, or get all three in the Density Kit.

Signature scent

Our signature scent took 1.5 years to develop with a sustainable perfumer in Paris, built around three goals: it had to smell incredible, contain zero endocrine-disrupting ingredients, and work on sensitive skin. It’s a blend of natural and synthetic molecules, each tested by toxicologists for hormone safety and dermatologists for sensitive skin, chosen for both human and environmental safety. Most brands hide behind the word “parfum” so they never have to disclose what’s actually in the bottle. We do the opposite: full ingredient disclosure is on our website, because we’re proud of the work that went into this formula.

Every ingredient, fully disclosed. Not "parfum."
