Why hair, skin & nails change

Six root causes this formula supports

Hair, skin, and nails don't change for one reason. They change because several systems shift at once. This formula was built around the six that matter most.

Estrogen, thyroid, and cortisol shift across your life — and your hair follicles feel every change. This formula supports the nutrient pathways those hormones rely on.
Biotin, zinc, vitamin D, and selenium build new hair, skin, and nail cells every day. Modern diets miss the mark more often than people realize. All six included.
UV light and free radicals damage cells. Vitamin C, vitamin E, and selenium support your body's antioxidant defense — protecting hair and skin cells.
After 30, your body produces about 1% less collagen each year. Hydrolyzed collagen peptides plus vitamin C supply the building blocks your body uses to rebuild it.
Every hair moves through growth, rest, and shed phases — driven by signals at the follicle. Vitamin D, zinc, and pumpkin seed extract support the signaling pathways your body uses to keep that cycle steady.
Hair and nails are built almost entirely from keratin — a protein assembled from sulfur amino acids. L-cysteine, MSM, and bamboo silica supply the raw materials your body uses to build it.

The Formula

Eleven research-backed actives.

Selected by our physician for their role in supporting hair, skin, and nail health.

Hero shot placeholder
Hydrolyzed Collagen
Hydrolyzed Collagen Peptides 350 MG
Bovine source · bioactive peptides

Provides amino acids — especially glycine, proline, and hydroxyproline — that your body uses to build collagen, the structural scaffold in skin dermis, hair follicles, and nail matrices.*

Collagen peptides have been studied in randomized trials for their role in supporting skin elasticity, hair density, and nail growth as part of consistent daily intake.
Hero shot placeholder
MSM
MSM 50 MG
Methylsulfonylmethane · bioavailable sulfur

An organic sulfur compound your body uses to cross-link collagen and form the disulfide bonds in keratin — the structural framework of hair and nails.*

Clinically studied at 1–3g/day for hair and skin condition over 12 weeks or longer. Dose-dependent effects documented in randomized supplementation studies.
Hero shot placeholder
Bamboo Silica
Bamboo Silica 15 MG
Bambusa arundinacea extract · bioavailable silicon

Silicon cross-links collagen fibers and supports the mineralization of hair and nail matrices. Bamboo is one of the most bioavailable natural sources of silica your body can absorb.*

Silicon supplementation has been studied in randomized trials for hair strand thickness, tensile strength, and nail resilience — commonly in combination with other nutrients.
Hero shot placeholder
Pumpkin Seed Extract
Pumpkin Seed Extract 50 MG
Cucurbita pepo · standardized phytosterols

Contains plant compounds, including phytosterols and lignans, studied for supporting 5-alpha reductase modulation — the enzyme pathway that converts testosterone to DHT, a hormone linked to pattern hair changes.*

Pumpkin seed has been studied in a 24-week randomized trial for its effect on hair count in men with pattern hair changes.
Hero shot placeholder
L-Cysteine
L-Cysteine 10 MG
Sulfur-containing amino acid

An amino acid your body uses to form the disulfide bonds in keratin — the chemical links that give hair its tensile strength. Roughly 10–15% of keratin is composed of cysteine residues.*

Clinically tested at 500–1,000mg/day in combination with keratin hydrolysate. Studies show improvements in hair density and tensile strength in cases of telogen effluvium over 8–12 weeks.
Hero shot placeholder
Biotin
Biotin 10,000 MCG
Vitamin B7 · keratin synthesis cofactor

An essential cofactor your body uses in keratin synthesis — the structural protein in hair and nails. Biotin supports normal hair, skin, and nail formation when daily intake is adequate.*

Included to ensure adequate daily intake. Clinical benefit is strongest in cases of biotin insufficiency; daily supplementation supports normal keratin production.
Hero shot placeholder
Vitamin C
Vitamin C 30 MG
Ascorbic acid · collagen synthesis cofactor

A required cofactor for the enzymes that cross-link and stabilize collagen. Without adequate vitamin C, your body can't properly assemble the collagen scaffolds that give skin its elasticity and hair follicles their structural support.*

Pairs synergistically with collagen peptides. Combination studies of collagen + vitamin C show greater effects on hair density and skin parameters than collagen alone.
Hero shot placeholder
Vitamin D3
Vitamin D3 35 MCG
Cholecalciferol · fat-soluble vitamin

Hair follicles express vitamin D receptors. D3 supports normal follicle cycling between growth and resting phases and helps modulate inflammatory signaling pathways linked to hair shedding.*

Mechanism documented in 2024 research on NLRP3 and HIF-1α pathways. Clinical evidence is strongest in individuals with vitamin D-associated telogen effluvium.
Hero shot placeholder
Vitamin E
Vitamin E 6 MG
Tocopherol · fat-soluble antioxidant

A fat-soluble antioxidant that protects the lipid membranes of skin cells and hair follicles from UV and environmental free radical damage. Works synergistically with selenium as part of the body's antioxidant defense system.*

50+ years of dermatological research supports vitamin E's role in photoprotection and protection of follicle cells from oxidative stress.
Hero shot placeholder
Zinc
Zinc 5 MG
Essential trace mineral · 300+ enzyme cofactor

Your body uses approximately 20mg of zinc daily to maintain hair follicle cycling. Zinc supports keratin synthesis, follicle stem cell signaling, and the antioxidant enzymes that protect dermal papilla cells.*

Cross-sectional research links zinc status to hair density. Daily replenishment supports normal follicle function and immune tolerance at the hair follicle.
Hero shot placeholder
Selenium
Selenium 25 MCG
Trace mineral · selenoprotein precursor

Incorporated into glutathione peroxidase — your scalp's master antioxidant enzyme that protects hair follicle stem cells from oxidative damage. Also supports thyroid hormone conversion, which regulates hair growth cycles.*

Dosed within the narrow therapeutic window (RDA 55µg, UL 400µg). Adequate intake supports selenoprotein synthesis and indirect thyroid-mediated hair cycling.
Dr. Renanit E. Barron, MD

When patients come to me with thinning hair, the conversation almost always leads back to their hormones — thyroid, cortisol, estrogen, and the nutrients those systems depend on. So I built the gummy I’d hand to my own patients.

What to expect over time

Hair, skin, and nail changes follow your body's natural cycles — nails respond faster than hair.

1 MONTH
Working at the cellular level
Formula absorbs and begins working at the cellular level. Most users don't notice visible changes yet. Consistency matters more than duration at this stage.
2–3 MONTHS
Early signs in nails
Some users begin noticing changes in nail texture or strength. Hair changes typically take longer due to follicle cycling timelines.
3+ MONTHS
Compounding hair & skin changes
Hair and skin changes become more noticeable as the formula compounds over successive growth cycles.
Taking the Hair, Skin & Nails Gummies as part of a daily routine

Two gummies, once a day.
That’s the routine.

1.Eat two gummies each morning, with or without food.
2.Anchor it to something you already do — coffee, brushing your teeth, your morning vitamins. Consistency is what makes the formula work.
3.Continue daily for at least 90 days. Hair and skin changes follow your body’s natural cycles.

Transparency you can actually see.

Most gummies hide behind proprietary blends or sprinkle in a few trendy ingredients. I liked that every ingredient and dose is clearly listed, and the formula actually feels intentional instead of packed with random extras.

FAQs

How long before I see results?+
Hair, skin, and nail support takes time because it follows your body's natural growth cycles. Most users notice changes in nail texture or strength within 2–3 months. Visible changes in hair density typically take 3–6 months of consistent daily use, since hair follicles cycle over months, not weeks. Give the formula at least 3 months before judging results.
Will this work for my type of thinning?+
DR BARRON is designed for thinning hair from common, non-genetic causes — stress, postpartum changes, perimenopause and menopause, hormonal shifts, post-illness recovery, and age-related thinning. It is not designed for genetic hair loss (androgenic alopecia / male- or female-pattern), alopecia areata, or thinning caused by underlying medical conditions. If your thinning runs in your family or you've experienced rapid or patchy loss, we recommend seeing a board-certified dermatologist.
What's the difference between the gummies and the serum?+
The Gummies work from the inside — providing nutrients your body uses to support hair, skin, and nail health (biotin, collagen peptides, zinc, selenium, vitamin D, and more). The Serum works at the surface — a topical formula with copper peptides, rosemary leaf extract, and caffeine, designed to support scalp health and follicle activity. Designed to work together, but each can be used on its own.
How does the subscription work?+
Two subscription options: a Quarterly plan ships every 90 days (save 30%) and a Monthly plan ships every 30 days (save 20%). Pause, skip, or cancel anytime from your account — no fees, no obligation.
What is your money-back guarantee?+
The Quarterly subscription is backed by a 90-day money-back guarantee. The Monthly subscription and one-time purchases are backed by a 30-day money-back guarantee. Either way, contact our team for a full refund — no return required on opened bottles.
Can I take this with other supplements or medications?+
The formula uses food-grade vitamins, minerals, and standard botanicals at doses within established daily intake ranges. It's designed to be compatible with most supplement routines. If you take prescription medications, are pregnant or nursing, or have a thyroid or hormonal condition, check with your physician before starting any new supplement, including this one.

Why hair, skin & nails change

Six root causes this formula supports

Hair, skin, and nails don't change for one reason. They change because several systems shift at once. This formula was built around the six that matter most.

Hormones

Estrogen, thyroid, and cortisol shift across your life — and your hair follicles feel every change. Perimenopause, postpartum, GLP-1 weight loss, and chronic stress can all disrupt the follicle cycle. This formula supports the nutrient pathways those hormones rely on.

Nutrient gaps

Your body uses biotin, zinc, vitamin D, and selenium to build new hair, skin, and nail cells every day. Modern diets miss the mark on these more often than people realize. All six included as part of your daily nutrient intake.

Oxidative stress

UV light and environmental free radicals damage the cells that hold your follicles and skin together. Vitamin C, vitamin E, and selenium support your body's natural antioxidant defense — protecting the structural integrity of hair and skin cells.

Collagen decline

After 30, your body produces about 1% less collagen each year. That structural protein gives skin its bounce and anchors every follicle to the dermis. Hydrolyzed collagen peptides plus vitamin C supply the amino acids and cofactors your body uses to rebuild it.

Follicle cycling

Every hair moves through a growth phase, a rest phase, and a shedding phase — driven by signals at the follicle. Vitamin D, zinc, and pumpkin seed extract support the signaling pathways your body uses to keep that cycle steady.

Keratin synthesis

Hair and nails are built almost entirely from keratin — a protein your body assembles from sulfur amino acids like cysteine. L-cysteine, MSM, and bamboo silica supply the raw materials your body uses to build keratin from the ground up.

Pumpkin Seed Extract
Pumpkin Seed Extract 50 MG
Cucurbita pepo · standardized phytosterols

Contains plant compounds, including phytosterols and lignans, that have been studied for their role in supporting 5-alpha reductase modulation — the enzyme pathway that converts testosterone to DHT, a hormone linked to pattern hair changes.*

Pumpkin seed has been studied in a 24-week randomized trial for its effect on hair count in men with pattern hair changes.
Hero shot placeholder
L-Cysteine
L-Cysteine 10 MG
Sulfur-containing amino acid

An amino acid your body uses to form the disulfide bonds in keratin — the chemical links that give hair its tensile strength. Roughly 10–15% of keratin is composed of cysteine residues. Also serves as a precursor to glutathione, an antioxidant active at the hair follicle.*

Clinically tested at 500–1,000mg/day in combination with keratin hydrolysate. Studies show improvements in hair density and tensile strength in cases of telogen effluvium over 8–12 weeks.
Hero shot placeholder
Biotin
Biotin 10,000 MCG
Vitamin B7 · keratin synthesis cofactor

An essential cofactor your body uses in keratin synthesis — the structural protein in hair and nails. Biotin supports normal hair, skin, and nail formation when daily intake is adequate.*

Included to ensure adequate daily intake. Clinical benefit is strongest in cases of biotin insufficiency; daily supplementation supports normal keratin production.
Hero shot placeholder
Vitamin C
Vitamin C 30 MG
Ascorbic acid · collagen synthesis cofactor

A required cofactor for the enzymes that cross-link and stabilize collagen. Without adequate vitamin C, your body can't properly assemble the collagen scaffolds that give skin its elasticity and hair follicles their structural support.*

Pairs synergistically with collagen peptides. Combination studies of collagen + vitamin C show greater effects on hair density and skin parameters than collagen alone.
Hero shot placeholder
Vitamin D3
Vitamin D3 35 MCG
Cholecalciferol · fat-soluble vitamin

Hair follicles express vitamin D receptors. D3 supports normal follicle cycling between growth and resting phases and helps modulate inflammatory signaling pathways linked to hair shedding.*

Mechanism documented in 2024 research on NLRP3 and HIF-1α pathways. Clinical evidence is strongest in individuals with vitamin D-associated telogen effluvium.
Hero shot placeholder
Vitamin E
Vitamin E 6 MG
Tocopherol · fat-soluble antioxidant

A fat-soluble antioxidant that protects the lipid membranes of skin cells and hair follicles from UV and environmental free radical damage. Works synergistically with selenium as part of the body's antioxidant defense system.*

50+ years of dermatological research supports vitamin E's role in photoprotection and protection of follicle cells from oxidative stress.
Hero shot placeholder
Zinc
Zinc 5 MG
Essential trace mineral · 300+ enzyme cofactor

Your body uses approximately 20mg of zinc daily to maintain hair follicle cycling. Zinc supports keratin synthesis, follicle stem cell signaling, and the antioxidant enzymes that protect dermal papilla cells.*

Cross-sectional research links zinc status to hair density. Daily replenishment supports normal follicle function and immune tolerance at the hair follicle.
Hero shot placeholder
Selenium
Selenium 25 MCG
Trace mineral · selenoprotein precursor

Incorporated into glutathione peroxidase — your scalp's master antioxidant enzyme that protects hair follicle stem cells from oxidative damage. Also supports thyroid hormone conversion, which regulates hair growth cycles.*

Dosed within the narrow therapeutic window (RDA 55µg, UL 400µg). Adequate intake supports selenoprotein synthesis and indirect thyroid-mediated hair cycling.
Dr. Renanit E. Barron, MD

When patients come to me with thinning hair, the conversation almost always leads back to their hormones — thyroid, cortisol, estrogen, and the nutrients those systems depend on. So I built the gummy I'd hand to my own patients. Eleven actives my team selected for hair, skin, and nail support — including a bamboo silica and biotin combination studied in a 2025 randomized trial for hair shedding and nail health.

What to expect over time

Hair, skin, and nail changes follow your body's natural cycles — nails respond faster than hair.

1 MONTH
Working at the cellular level
Formula absorbs and begins working at the cellular level. Most users don't notice visible changes yet. Consistency matters more than duration at this stage.
2–3 MONTHS
Early signs in nails
Some users begin noticing changes in nail texture or strength. Hair changes typically take longer due to follicle cycling timelines.
3+ MONTHS
Compounding hair & skin changes
Hair and skin changes become more noticeable as the formula compounds over successive growth cycles.
Taking the Hair, Skin & Nails Gummies as part of a daily routine

Two gummies, once a day.
That’s the routine.

1.Eat two gummies each morning, with or without food.
2.Anchor it to something you already do — coffee, brushing your teeth, your morning vitamins. Consistency is what makes the formula work.
3.Continue daily for at least 90 days. Hair and skin changes follow your body’s natural cycles.

★★★★★ Rachel R.
Transparency you can actually see.

Most gummies hide behind proprietary blends or sprinkle in a few trendy ingredients. I liked that every ingredient and dose is clearly listed, and the formula actually feels intentional instead of packed with random extras.

Finally replaced my whole supplement shelf.

I was tired of juggling powders, capsules, and drinks every morning. These made everything way simpler, and they’re honestly the first wellness gummies I’ve stayed consistent with.

★★★★★ Joey E.
Way better than I expected them to taste.

Usually gummies with this many ingredients taste overly sweet or artificial, but these actually taste clean. They’ve become part of my daily routine without even thinking about it.

The convenience is what hooked me.

I travel a lot and wanted something easy to throw in my bag without dealing with shaker bottles or powders. These made staying consistent ridiculously easy.

★★★★★ Michelle L.
They actually feel premium.

A lot of wellness gummies feel gimmicky or candy-like. These don’t. The ingredients feel thoughtfully chosen, the taste is great, and the whole experience feels much higher quality.

FAQs

How long before I see results?+
Hair, skin, and nail support takes time because it follows your body's natural growth cycles. Most users notice changes in nail texture or strength within 2–3 months. Visible changes in hair density typically take 3–6 months of consistent daily use, since hair follicles cycle over months, not weeks. Give the formula at least 3 months before judging results.
Will this work for my type of thinning?+
DR BARRON is designed for thinning hair from common, non-genetic causes — stress, postpartum changes, perimenopause and menopause, hormonal shifts, post-illness recovery, and age-related thinning. It is not designed for genetic hair loss (androgenic alopecia / male- or female-pattern), alopecia areata, or thinning caused by underlying medical conditions. If your thinning runs in your family or you've experienced rapid or patchy loss, we recommend seeing a board-certified dermatologist.
What's the difference between the gummies and the serum?+
The Gummies work from the inside — providing nutrients your body uses to support hair, skin, and nail health (biotin, collagen peptides, zinc, selenium, vitamin D, and more). The Serum works at the surface — a topical formula with copper peptides, rosemary leaf extract, and caffeine, designed to support scalp health and follicle activity. Designed to work together, but each can be used on its own.
How does the subscription work?+
Two subscription options: a Quarterly plan ships every 90 days (save 30%) and a Monthly plan ships every 30 days (save 20%). Pause, skip, or cancel anytime from your account — no fees, no obligation.
What is your money-back guarantee?+
The Quarterly subscription is backed by a 90-day money-back guarantee. The Monthly subscription and one-time purchases are backed by a 30-day money-back guarantee. Either way, contact our team for a full refund — no return required on opened bottles.
Can I take this with other supplements or medications?+
The formula uses food-grade vitamins, minerals, and standard botanicals at doses within established daily intake ranges. It's designed to be compatible with most supplement routines. If you take prescription medications, are pregnant or nursing, or have a thyroid or hormonal condition, check with your physician before starting any new supplement, including this one.
