Product analysis

58 out of 100

Heavenly Hair Tropical Citrus may help hair shedding caused by low biotin intake. Support for brittle nails is less certain, and its biotin is relatively costly for the amount provided.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality48

The biotin is clearly identified as the biologically active D form. Other ingredients are less clearly described, and the silica and horsetail details do not establish the silicon preparation used in the relevant cosmetic research.

Ingredient Transparency72

Ingredient amounts are disclosed and some forms are identified. Unspecified forms still limit like-for-like comparisons.

Value For Money45

Biotin is relatively costly, while the keratin and silicon comparisons are more favorable. Several other ingredient comparisons remain uncertain, so the price advantage is uneven across the formula.

Customer Satisfaction70

Customer feedback is strongly positive. The relatively small review pool limits how representative that feedback may be.

Product Focus67

Biotin provides the clearest connection to hair shedding from low intake, with more limited support for brittle nails. The other small or incompletely characterized ingredients do not establish added cosmetic benefits, and the large biotin amount does not imply better results.

Silicon · 21 mgBiotin · 3000 mcgHorsetail · 25 mgKeratin · 25 mg

Biotin is the main nail-related ingredient here, with limited support from small brittle-nail studies and a short-term growth study. Its 3000 mcg per serving receives full amount credit, without establishing repeated daily exposure or durable benefit. Keratin is below the inclusion threshold and does not establish equivalence to the studied feather keratin preparation. Silica and horsetail do not establish the elemental silicon exposure used in the relevant nail study.

How this product is rated for Nail Health

Ingredient fit82

Biotin is the sole credited ingredient, alongside other ingredients outside its supported nail role.
Goal fit
Biotin is the sole credited ingredient, alongside other ingredients outside its supported nail role.
Dose adequacy
Biotin reaches the upper comparison range; keratin, horsetail and zinc fall below inclusion thresholds.

Pathways70

Coverage is concentrated in nutrient cofactors involved in forming nail keratin; structural protein and silicon-related coverage remain absent.
Depth
Biotin leads the assigned coverage of nutrient cofactors for nail keratin formation.
Breadth
Only nutrient cofactors reach the coverage threshold; structural protein and silicon-related support do not.

Evidence100

Biotin carries the strongest assigned evidence weight, but the relevant studies are small and provide limited certainty about lasting nail improvement.
Evidence strength
Biotin has the strongest assigned evidence weight, with limited controlled evidence for durable nail improvement.
Studied preparation
The credited preparations are recognized in the saved findings; this does not establish a lasting nail benefit.

Formulation logic100

Credited ingredients have no missing required partner, and no configured ingredient conflict was identified.
Partner coverage
Every credited ingredient works independently or has its required partner; this does not establish an added combination benefit.
Conflicts
No configured ingredient conflict was identified.
Effective doses
All credited ingredients meet the comparison's amount threshold; smaller or unresolved quantities are not included.

Biotin · 3000 mcgZinc · 5.5 mgKeratin · 25 mg

Biotin can help address diffuse shedding caused by inadequate intake, without established regrowth benefit when intake is adequate. The smaller keratin and zinc declarations are not counted in the saved findings. Generic keratin does not establish equivalence to the reviewed hair-gloss preparation, while silica and horsetail do not establish the elemental silicon preparation used for hair-shaft strength and thickness.

How this product is rated for Hair Health

Ingredient fit79

Vitamin B7 (Biotin) is a principal counted ingredient. Keratin, Horsetail, Zinc is not counted at the declared amount.
Goal fit
The counted hair-related ingredients sit within a broader formula that also serves other purposes.
Dose adequacy
Vitamin B7 (Biotin)'s counted amount fully matches the saved comparison range, without establishing an effective hair-growth dose.

Pathways0

The counted nutrient contributions do not extend to the reviewed androgen, hair-fibre, follicle-antioxidant or stress-related routes.
Depth
No contribution is assigned to the reviewed hair-specific routes.
Breadth
No hair-specific route reaches the saved threshold for substantial coverage.

Evidence80

Vitamin B7 (Biotin) leads the saved evidence contribution. Preparation-specific findings and nutrient functions do not establish routine regrowth in every adult.
Evidence strength
Vitamin B7 (Biotin) provides the leading evidence contribution in the saved findings; its supplied limitations still govern the hair benefits that can be expected.
Studied preparation
The counted preparations are recognized in the saved findings; this does not establish routine regrowth or interchangeable botanical preparations.

Formulation logic100

The counted ingredients have no unmet partner requirement or configured conflict. Amount eligibility is considered separately from demonstrated hair benefit.
Partner coverage
The counted ingredients have no unmet partner requirement; combining them does not establish added hair benefit.
Conflicts
No configured ingredient conflict is identified in the saved findings.
Effective doses
All counted ingredients clear the saved minimum amount comparison; this is not a proven effective hair-growth dose.

Zinc · 5.5 mgSilicon · 21 mg

Biotin and zinc support normal skin functions, particularly when nutritional needs are unmet. The 3,000 mcg biotin amount is much higher than ordinary nutritional needs and does not imply additional cosmetic benefit.

The supplied silicon amount and preparation are unresolved, so horsetail material cannot be compared directly with the reviewed elemental-silicon preparation. Keratin and fruit-source mass likewise offer limited support for a specific skin outcome.
