You trust your shampoo. But do you really know what’s inside it?

FDA FACT: Liquid shampoos contain phthalates, and behind a simple word like “fragrance” may be multiple chemicals that are harmful to human health!

You use it several times a week, sometimes for years, thinking you’re simply cleansing your hair. Yet with every wash, that formula comes into direct contact with your scalp, without you necessarily knowing everything it contains.

READ THIS BEFORE YOUR NEXT WASH  •   SOURCES: FDA + NIH/NIEHS

A Widening Part Isn’t Always “Just Age.” Your Hair May Be Reflecting A Bigger Hormonal Shift.

The American Academy of Dermatology notes that hormonal imbalance and thyroid disease can lead to thinning hair or hair loss. NIDDK also lists fatigue, dry or thinning hair, and heavy or irregular periods among possible thyroid-related symptoms. One symptom proves nothing. Several changes at once deserve attention.

Your Part Looks Wider

More scalp shows in photos, under bathroom lights, or whenever your hair is wet.

More Hair Stays In The Brush

The amount in the brush, drain, or on your pillow suddenly feels impossible to ignore.

Hair Feels Drier, Finer, More Fragile

The texture changes. Lengths snap. The hair you still have can feel noticeably less dense.

Fatigue, Dry Skin Or Cycle Changes

Hair may not be the only signal. Hormone-related conditions can show up across the body.

THE REAL QUESTION MAY BE THIS: You pay attention to what you eat and what you put on your face. So why never question what you massage into your scalp, wash after wash?

The fragrance in your liquid shampoo is the cause!

Stop before the damage becomes irreversible!

Too many ingredients you don’t recognize.
Too many complex fragrances.
Too many bottles.
Too many products added to fix what the last ones left behind.

At some point, you have to stop adding more.

And start over with something simpler.

A natural formula. A straightforward ritual. A product that starts where your routine should have started all along: your scalp.

Hair Can Reflect Hormonal Health

“Dry, thinning hair” is listed by NIDDK among possible symptoms of hypothyroidism, alongside fatigue and heavy or irregular menstrual periods. The American Academy of Dermatology also notes that hormonal imbalance can cause thinning hair or hair loss.

The Questions A Smart Skeptic Should Ask.

No evasions, no white-coat theater, and no claim that a shampoo can diagnose or treat a hormonal condition.

Are you claiming liquid shampoo causes hormone problems?

Yes. The FDA states that phthalates, as used in cosmetics, pose a health risk. NIEHS explains that cosmetics, including shampoos, may contain phthalates and that endocrine-disrupting chemicals can block and/or interfere with hormone signaling. This may therefore contribute to hair loss.

 

Then why talk about thinning hair and widening parts?

Because the American Academy of Dermatology says hormonal imbalance can cause thinning hair or hair loss, and NIDDK lists dry, thinning hair among possible hypothyroidism symptoms.

Is ZeroVia a hair-growth treatment?

No. ZeroVia is a cosmetic solid shampoo, not a drug or treatment. Its purpose is to deeply nourish the scalp, help remove excess oil and product buildup, and promote fresher, lighter, fuller-looking roots.

Will it work on fine, flat or oily hair?

It is designed for a direct-to-scalp wash, which can suit roots that feel oily, coated or easily weighed down. Verified customers describe fresher roots and more lift.

Do I still need conditioner or styling products?

No, there’s no need. The ritual is simple: wet your scalp, glide the bar directly over your roots, massage for about 60 seconds, rinse thoroughly, then care for your lengths according to your hair type.

 

How long does one bar last?

ZeroVia states approximately 40–60 washes per bar. Actual longevity depends on hair length, frequency of washing, storage and how much product you use.

What if I do not love it?

The current store policy includes a 90-day money-back guarantee. Follow the return terms shown by ZeroVia if the bar is not right for you.
