A letter from Lovisa

I lost my period for over a year.

My doctor blamed hormones. My mom blamed my haircare.

She wasn't wrong.

So my mother Christina and I built a brand that does something about it. Every formula independently tested by toxicologists, verified free from hormone-disrupting ingredients.

Don't let life, toxins, or your beauty routine get Under Your Skin.

Questions you are probably asking.

  • Question: Is this actually different from other clean brands?

    Answer: Most clean brands have a banned list. Ours has over 2,100 ingredients on it, more than any regulatory standard requires anywhere in the world. And then we go further than any list can. Every finished formula is independently tested by toxicologists at Sweden's national research institute for endocrine disruption, carcinogens, bioaccumulation, and biodegradability. That second step is what no other haircare brand has done.

  • Question: Will it actually work on my hair?

    Answer: We have a 150-day external clinical study showing 89% reduction in hair loss and a consumer study of 50 subjects showing 98% noticed new baby hairs in 60 days. Hair loss has many causes and results vary. But these numbers are real, the ingredients are clinically proven, and 200,000 women have made the switch.

  • Question: Is it worth the price?

    The Density Kit replaces three products you are probably already buying separately. And it is the only haircare you will own that has been independently verified hormone-conscious. For most of our customers that is not a luxury. It is the baseline.
