Biotin is the best-known hair vitamin, and vitamin C helps your body absorb iron and build collagen. The Hair Love Duo puts both in one fully vegan routine. Here's what each does, and what's realistic to expect.

Do biotin and vitamin C help hair?
Biotin is essential for healthy hair, and low biotin can cause thinning, but studies show the clearest benefit in people who are actually deficient[1][2]. Vitamin C supports collagen formation and helps your body absorb iron from plant foods[3], which matters because low iron is a common factor in hair shedding. Together they make a simple vegan routine, not a guaranteed growth treatment.

What's inside
- Biotin Gummies 5,000mcg, Vegan, 40ct: 5,000mcg biotin per two-gummy serving.
- Vegan Vitamin C Gummies 250mg, 60ct: a full 250mg serving of vitamin C.
Both are plant-based, with no animal-sourced collagen or gelatin.
What biotin does (and doesn't do)
Biotin is a B vitamin your body uses to turn food into energy, and it plays a role in keratin, the protein that makes up hair and nails. Biotin deficiency can cause hair thinning and brittle nails[1]. A 2017 review found that the cases where biotin improved hair or nails almost all involved people with an underlying deficiency or condition[2]. In other words, biotin fills a gap well. It isn't proven to supercharge hair that's already well-nourished.
Important: high-dose biotin can interfere with some lab tests, including thyroid and heart tests[1]. Always tell your doctor you take it before bloodwork.
Where vitamin C fits
Vitamin C helps your body build collagen, a structural protein in skin and around hair follicles, and it improves absorption of non-heme iron, the kind found in plant foods[3]. That's especially useful on a vegan or vegetarian diet. If you're noticing more shedding than usual, it's worth asking your doctor to check your iron levels, too.
The honest summary
- Biotin helps most when you're low in it.
- Vitamin C supports collagen and iron absorption from plant foods.
- Hair grows slowly, so expect a few months before judging any routine.

Frequently asked questions
Is 5,000mcg of biotin too much?
It's well above the 30mcg daily need, but no upper limit has been set because biotin hasn't been shown to cause toxicity[1]. The main concern is lab test interference, so tell your doctor you take it.
Is this bundle vegan?
Yes, both gummies are vegan.
How long until I see results?
Hair grows about half an inch a month, so give it at least three months of daily use.
