HelloPharmacist Scorecard of Hairfluence Watermelon by ZHOU

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Partial disclosure
Ingredient Transparency · database check
Partial

Most active ingredients list an amount, but at least one is hidden in a blend or missing.

Why this rating?
  • The label discloses an exact amount for 2 of its 3 active ingredients.
  • “Hairfluence Blend” is a proprietary blend — the label gives one combined amount (23 mg) without saying how much of each component you get.
  • “Bamboo stem extract” is listed as a grouped ingredient — the label gives one combined amount (23 mg) without saying how much of each component you get.

Hairfluence Watermelon is a liquid supplement with 3 active ingredients. Silica (a form of silicon) is included for bone and connective tissue support.

Biotin is a B vitamin that helps cells convert food into energy and plays a role in hair, skin, and nail health. Keratin is a structural protein that forms the core of hair strands.

The product also contains inactive ingredients — purified water, natural watermelon flavor, citric acid, stevia leaf extract, vegetable juice concentrate, potassium sorbate, and acacia gum — which serve as the liquid base, flavor, sweetener, and preservatives.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: longer, stronger, healthier hair growth.
  • We looked for evidence on: Androgenic alopecia, Alopecia areata, Brittle nails, Biotin deficiency, hair thinning, hair loss — and 1 related terms.
  • The strongest evidence on file: Biotin is rated "Likely Effective" for Biotin deficiency (Natural Medicines).
  • Also on file: Biotin is rated "Insufficient Reliable Evidence To Rate" for Alopecia areata, Brittle nails.
  • Also on file: Silicon is rated "Insufficient Reliable Evidence To Rate" for Androgenic alopecia.

Silica shows possibly effective evidence for osteoporosis support, though the evidence for hair loss (androgenic alopecia) is insufficient to rate. Biotin is likely effective for true biotin deficiency, but shows possibly ineffective ratings for multiple sclerosis and seborrheic dermatitis; evidence for alopecia areata is insufficient.

We don't have effectiveness data on file for keratin in this product. The evidence for how well this supplement works to promote hair health specifically is not established in the data we hold.

The evidence, ingredient by ingredient Biotin Bamboo

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Silica from food and supplements is generally well tolerated at typical doses, though long-term high-dose safety hasn't been thoroughly studied. The safety data advises against silica during pregnancy and breastfeeding.

Biotin is generally considered safe and well tolerated, even at fairly high doses, since excess amounts are cleared through urine; a small number of people taking high-dose biotin have reported mild diarrhea. Biotin is likely safe in pregnancy and breastfeeding at normal dietary and supplement amounts, though check with your doctor about high-dose products.

Pregnancy and breastfeeding safety data for keratin is not on file.

Side effects, ingredient by ingredient Biotin Bamboo

Antithyroid Drugs

Theoretically, long-term bamboo use might increase the effects and adverse effects of antithyroid drugs, possibly leading to hypothyroidism.
Animal research suggests that long-term consumption of bamboo shoot can decrease thyroid peroxidase activity, as well as levels of thyroxine (T4) and triiodothyronine (T3). This effect has not yet been reported in humans.

Hairfluence Watermelon by ZHOU: Common Questions

Does Hairfluence Watermelon by ZHOU interact with any medications?
Yes. Based on its ingredients, Hairfluence Watermelon has a known interaction with 5 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Hairfluence Watermelon contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is this safe during pregnancy?
Silica safety data advises against it during pregnancy. Biotin is likely safe at normal dietary amounts, but you should talk with your doctor or pharmacist before taking supplements during pregnancy, as safety data for keratin is not on file.
Is this safe while breastfeeding?
Silica safety data advises against it while breastfeeding. Biotin is likely safe at normal amounts, but check with your doctor or pharmacist about this product while nursing, since we don't have breastfeeding safety data for keratin.
Will this help with hair loss?
Biotin has insufficient evidence for alopecia areata, and silica's evidence for androgenic alopecia (male or female pattern hair loss) is also insufficient to rate. The effectiveness of this supplement for hair loss specifically is not well established in the data we hold.
What does biotin do?
Biotin is a B vitamin that helps your cells turn food into energy and plays a role in hair, skin, and nail health. It's likely effective if you have a true biotin deficiency, though that's rare in people eating a typical diet.
Why is silica in this product?
Silica (a form of silicon) is included because it shows possibly effective evidence for osteoporosis support. It's generally well tolerated at typical supplement doses, though long-term safety at high doses hasn't been well studied.
What side effects might I experience?
Both silica and biotin are generally well tolerated. High-dose biotin has rarely caused mild diarrhea in a small number of people. Silica from food and supplements at normal amounts is not associated with adverse effects.
