Hair Loss & Brittle Nails? Your Body Is Sending a Warning

What two droppers actually delivers

The nutrients your
follicles have been waiting for.

You can't eat your way to this much biotin and zinc every day. A capsule delivers half of it. Two droppers of HOLSTC delivers nearly all of it.

🍳

10 eggs

Worth of Biotin. The reason your biotin capsule didn't move your nails: the dose your follicles received was never enough. This finally crosses the threshold.

~700 calories

🐟

200 servings of tuna

Worth of B12. Hair follicles need cellular energy to grow — chronic under-dosing of B12 starves the process before it starts.

28,000+ calories

🌻

A handful of seeds daily

Worth of Zinc. Zinc regulates the hair growth cycle and repairs follicle tissue — often the first mineral to fall short when absorption is poor.

~160 calories

🥣

3 cups of Greek yogurt

Worth of Iodine. Your thyroid drives hair growth cycles — and iodine deficiency quietly slows follicle production without obvious symptoms.

~400 calories

Two droppers of HOLSTC delivers all of this — plus Copper, Vitamin A, Vitamin C, and 17 more nutrients. Zero prep. No capsule required.

HOLSTC Vitality Drops — liquid vs capsules

The upgrade

Liquid goes where
capsules can't.

HOLSTC Vitality Drops absorb directly under your tongue, straight into your bloodstream. Your digestive system doesn't touch it. Neither does the coating. Neither does the filler.

A biotin capsule absorbs at 40–50% — often less if you take it on an empty stomach. That means 100 mcg on the label delivers roughly 40–50 mcg to your cells. Liquid held under your tongue absorbs at ~90%. The follicle threshold is finally met. The follicle can finally respond.

Everything your follicles
need — finally at the right dose.

Brittle nails and hair shedding aren't a single-nutrient problem. These are the 23 nutrients your body needs to repair, grow, and hold on. You've tried some of them in capsule form. Here's what changes when the dose actually gets through.

Key Nutrient

Biotin (B7)

100 mcg

The primary nail nutrient — and the one most people are chronically under-dosing. Capsule biotin delivers 40–50% of the label dose. Often not enough to hit the threshold your nail bed needs to stop breaking.

Zinc

5 mg

Regulates keratin synthesis and nail matrix cell production. Often the first mineral to fall short when absorption is inefficient — and one biotin capsules rarely include.

Copper

1 mg

Works with zinc to build structural integrity in the nail plate. Low copper is frequently the hidden reason nails remain brittle even with biotin supplementation.

Selenium

100 mcg

Shields nail matrix cells from oxidative stress — the kind that accelerates brittleness and prevents the nail from growing out intact.

Vitamin C

100 mg

Drives collagen production that binds the nail layers together and strengthens the cuticle — deficiency is one of the fastest routes to peeling and cracking.

Manganese

2 mg

Activates the enzymes required for keratin synthesis — the structural protein your nails are made of. Manganese deficiency slows nail growth at the cellular level.

Vitamin A

900 mcg RAE

Regulates sebum production that nourishes the scalp and keeps follicles anchored. Without sufficient Vitamin A, follicles become dry and fragile — shedding accelerates.

Vitamin E

15 mg

Antioxidant protection for follicle cells. Oxidative stress at the follicle level is one of the primary drivers of shedding — Vitamin E neutralizes it before damage sets in.

Vitamin D

25 mcg

Directly activates hair follicle cycling. Research links Vitamin D deficiency to alopecia and thinning — and most supplementation stays in the deficient range because capsule absorption is incomplete.

Vitamin K

100 mcg

Supports scalp microcirculation — the blood flow that delivers nutrients to the base of each follicle. Poor circulation means even fully absorbed nutrients struggle to reach their target.

Iodine

150 mcg

Thyroid hormones regulate every phase of the hair growth cycle. Iodine deficiency quietly disrupts that cycle — shedding increases before any thyroid panel flags it.

Folate

400 mcg folate (as methylfolate)

Required for rapid cell division — follicles divide faster than almost any other cell in the body. Low folate slows that process and contributes to slower, weaker regrowth.

Boron

1 mg

Supports mineral balance at the follicle and improves how the body uses other hair nutrients — particularly magnesium and Vitamin D. A trace mineral most hair formulas skip.

Vitamin B12

500 mcg

Follicles are metabolically active — they need cellular energy to grow continuously. B12 deficiency starves that process. At 500 mcg absorbed at ~90%, the energy gap closes fast.

Riboflavin (B2)

3 mg

Powers the mitochondria in follicle cells — the cellular engines that keep hair actively in the growth phase rather than triggering premature shedding.

Niacin (B3)

10 mg NE

Drives blood flow to the scalp and supports ATP production in follicle cells. Poor scalp circulation is a major contributor to follicle miniaturization and thinning.

Thiamin (B1)

3 mg

Converts food into usable fuel at the cellular level — the energy source follicles run on throughout the hair growth cycle.

Pantothenic Acid (B5)

5 mg

Metabolic bridge between nutrients and cellular energy. B5 deficiency has been directly linked to hair loss in clinical research — it's rarely included in standalone biotin products.

Magnesium

25 mg

Activates ATP in every follicle cell and is required for protein synthesis including keratin. Without adequate magnesium, all other B-vitamins can't fully do their job.

Vitamin B6

2 mg

Regulates hormone signaling that affects the hair growth cycle — particularly androgen sensitivity. B6 deficiency can amplify hair loss in people already sensitive to hormonal shifts.

Chromium

100 mcg

Stabilizes blood sugar and insulin sensitivity. Blood sugar swings reduce the nutrients available to follicle cells — chromium smooths that delivery curve throughout the day.

Molybdenum

50 mcg

Powers the detox enzyme system that clears waste from cells — including follicle cells. When cellular cleanup stalls, follicle function degrades quietly over time.

Vanadium

10 mcg

Supports insulin-like activity at the cellular level, helping follicles maintain stable nutrient uptake between doses instead of cycling through peaks and valleys.

Other Ingredients: Distilled Water, Vegetable Glycerin, Citric Acid, Sunflower Lecithin, Xanthan Gum, Natural Flavor, Potassium Sorbate.

What to expect

Here's what changes,
and when.

Follicle repair doesn't happen overnight — but it does happen once the daily dose is finally getting through. Here's the typical progression.

Days 1–7

Energy and cuticle hydration improve

Most people notice energy first — B12 and B-vitamins respond quickly once the dose gets through. Cuticles begin to soften as cellular hydration improves. Small shift, but noticeable if you're paying attention.

Weeks 2–3

Nail bed begins to strengthen

New nail growth at the base starts coming in harder. The peeling at the corners begins to decrease. Hair in the shower starts pulling less. These are early signs the threshold is being met.

Month 2

Nails stop breaking — the first clear marker

For most people this is the moment it becomes real. You go to snap a nail and it doesn't. Hair shedding measurably slows. The follicles are finally receiving what they need to hold on.

Month 3+

Visible new growth — nails and hair

Nails growing past the fingertip for the first time in years. Noticeably less fill in the shower drain. This is what it looks like when consistent nutrition at the right absorption rate finally accumulates.

Results vary. Not satisfied in 30 days? Full refund — no questions.

Real customers, real names

They tried biotin before.
It didn't work either.

If your biotin didn't move the needle, that's a format problem — not a you problem. Here's what happened when the format changed.

"By month two I stopped breaking nails for the first time in years. I'd tried three different biotin brands. I didn't realize the issue was how my body was absorbing them."

Bella H.

Nails stopped breaking — month 2

"The hair shedding slowed noticeably by week six. I'd been treating it like a scalp problem for years. It was a nutrient problem the whole time — I just wasn't absorbing enough."

Melis K.

Shedding slowed by week 6

"I was convinced biotin just didn't work on me. I'd tried it four times. Switched to this and my nails started coming in harder after three weeks. The capsule was the problem, not the biotin."

Felicia J.

Harder nails in 3 weeks

"I noticed less in the shower first. Then the nails. Then a friend pointed out my hair looked fuller. None of that happened with any of the capsule vitamins I'd been taking."

Still on the fence?

What people ask
after biotin failed them.

I tried biotin before and it didn't work — what's actually different here?

The biotin itself isn't different — the form is. When biotin is in a capsule, it absorbs at 40–50%. That means 100 mcg on the label delivers roughly 40–50 mcg to your cells. When biotin is held under your tongue in liquid form, absorption reaches ~90%. The amount your follicles actually receive nearly doubles. That's the threshold most biotin capsules never cross — even with consistent daily use.

How long before I see a difference in my nails or hair?

Most people notice nail bed changes around weeks 2–3 — new growth coming in harder, less peeling at the cuticle. Nails stopping breaking entirely is usually around month 2. Hair shedding typically slows in the same window. The timeline depends on how depleted you are going in — the bigger the gap your body needs to close, the more time it takes. The 30-day guarantee covers the earliest visible window.

Is biotin the only thing in this, or is it a full multivitamin?

It's a full multivitamin — 23 nutrients total. Biotin alone addresses part of the problem, but brittle nails and hair shedding are typically multi-nutrient deficiencies. Zinc regulates the growth cycle. Copper builds structural integrity. Selenium protects follicle cells from oxidative stress. Vitamin C produces the collagen that anchors nails and hair. HOLSTC includes all of them at full absorption — which is why it works when standalone biotin capsules didn't.

Can I take this if I'm already taking a biotin supplement?

You can, but most people discontinue their standalone biotin once they switch. There's no conflict — biotin is water-soluble, so excess is excreted. But there's also no reason to double up. Two droppers of HOLSTC delivers 100 mcg of biotin at ~90% absorption, which exceeds what most capsule supplements are actually delivering to your cells even at higher label doses.

What does it taste like?

Strawberry Lemonade. It was formulated to be genuinely pleasant — because you need to take this every morning to see results, and that requires something you actually want to take. Most people mix it into water or take it straight. Either way, 30 seconds and you're done.
