Product analysis
Hair Skin & Nails offers a broad mix aimed at hair, skin and nail care, including biotin in a form the body can use. The collagen is costly for the amount provided, which matters if collagen is your main reason for buying.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality43
The biologically active biotin is a useful feature, while the silicon form is less favorable for absorption. Several other ingredient forms, including collagen, are not specified, leaving parts of the mixture harder to compare.
Ingredient Transparency70
Amounts are stated throughout the label, making quantity comparisons straightforward. Several forms and the proportions of the vitamin A mixture remain unclear.
Value For Money40
Value is mixed: the biotin is more reasonably priced, but the collagen is expensive for the amount provided. A favorable serving price for silicon does not resolve value for the rest of the mixture.
Customer Satisfaction87
Customer ratings are positive across a large body of feedback. The breadth of feedback supports a clearer picture of satisfaction, but does not prove results for hair, skin or nails.
Product Focus44
The formula appears reasonably aligned with its hair, skin and nail aims. Its long ingredient list makes it less concentrated on a small set of ingredients.

Biotin and zinc can help address low intake or deficiency associated with hair changes, but extra amounts do not establish regrowth when intake is adequate. The silicon is silicon dioxide, which cannot inherit the fine-hair findings for choline-stabilized orthosilicic acid. Collagen is present at only 60 mg per serving, far below the preparation-specific hair-condition study exposure, and received no contribution.
How this product is rated for Hair Health
Ingredient fit77
The formula’s hair relevance and usable amounts determine this finding. Smaller or unresolved amounts limit the contribution.
Goal fit
Hair-related ingredients sit within a broader formula, so some of the formula serves other purposes.
Dose adequacy
The recognized amounts contribute unevenly, with smaller or unresolved amounts limiting the finding.
Pathways0
No contribution was recorded for the four specific hair mechanisms considered here.
Depth
No contribution was recorded for the four specific hair mechanisms considered here.
Breadth
None of the specific mechanisms reached the required coverage level.
Evidence98
Zinc leads the saved evidence finding, with hair benefits still limited by its specific nutritional or preparation context.
Evidence strength
Zinc leads the saved evidence finding, with hair benefits still limited by its specific nutritional or preparation context.
Studied preparation
The contributing preparations matched those recognized in the saved result; this does not establish a trial of the complete product.
Formulation logic100
No required partner or configured conflict reduced the contributions. All counted amounts reached the minimum comparison threshold.
Partner coverage
No missing required partner reduced the recognized contributions; this does not demonstrate added benefit from combining ingredients.
Conflicts
No configured ingredient conflict was identified in the supplied calculation.
Effective doses
All counted ingredients reached the minimum amount threshold used in the saved result; that threshold is not a proven hair-growth dose.

Silicon · 30 mgCollagen · 60 mgBiotin · 5000 mcgHorsetail · 3 mg
Biotin has limited findings for brittle nails and nail growth from small, mostly uncontrolled studies. Higher amounts have not established greater or more durable benefit. Collagen’s nail findings come from a small uncontrolled VERISOL study, so generic collagen does not establish the same effect. Zinc may help address low intake associated with brittle or abnormal nails, without established extra benefit when intake is adequate.
How this product is rated for Nail Health
Ingredient fit67
Some amounts only partly match the supplied comparison range, limiting the amount-based contribution.
Goal fit
Several ingredients serve other nutritional purposes, giving the formula a broader focus than nail health.
Dose adequacy
Some amounts only partly match the supplied comparison range, limiting the amount-based contribution.
Pathways70
The saved findings emphasize nutrients involved in keratinization, without proving faster growth or reduced brittleness. One nail-related route reaches the supplied coverage threshold, limiting breadth.
Depth
The saved findings emphasize nutrients involved in keratinization, without proving faster growth or reduced brittleness.
Breadth

Evidence100
Biotin provides the leading saved evidence finding, but the nail studies are small and mostly uncontrolled.
Evidence strength
Biotin provides the leading saved evidence finding, but the nail studies are small and mostly uncontrolled.
Studied preparation
The saved findings recognize the included preparations; this does not strengthen the underlying study designs.
Formulation logic100
No required partner or matched conflict was identified. All retained ingredients pass the minimum amount comparison; this threshold is not a proven effective dose.

Vitamin C, zinc and several B vitamins have skin roles when intake is low, while biotin does not establish extra benefits with adequate nutrition. Collagen at 60 mg and hyaluronic acid at 1 mg per serving fell below the saved amount criteria. The silica source does not establish a studied elemental silicon preparation. Vitamin A supplied limited saved collagen-related coverage, but nutritional vitamin A cannot inherit prescription retinoid effects.
How this product is rated for Skin Health
Ingredient fit64
The formula contains relevant nutrients alongside small collagen and hyaluronic acid amounts.
Goal fit
The formula contains relevant nutrients alongside small collagen and hyaluronic acid amounts.
Dose adequacy
Amounts received partial recognition; silicon lacked a usable amount and several ingredients fell below the saved criteria.
Pathways40
Only collagen-related coverage reached the saved criterion, driven by vitamin A rather than a meaningful collagen peptide amount.

Only collagen-related coverage reached the saved criterion, driven by vitamin A rather than a meaningful collagen peptide amount.
Breadth
Only collagen-related coverage reached the saved criterion, driven by vitamin A rather than a meaningful collagen peptide amount.
Evidence83
Zinc drove the saved evidence finding; its clearest practical skin role concerns low intake.
