Myth-Busting Supplement: Unlock Your Radiant Hair

Biotin - Vitamin B7

Biotin—also known as vitamin B7—is a B-vitamin that helps your body turn food into energy and plays a key role in healthy cell growth. You’ll find it in foods like eggs, dairy, mushrooms, and cauliflower, and it’s often hyped as the go-to vitamin for hair growth.

It sounds like a dream: stronger strands, thicker volume, faster growth, and fewer split ends. And while yes—biotin is super important for your overall health (and deficiency can cause hair thinning), there’s a catch...

❌ Busted: Biotin ≠ Instant Mermaid Hair

Unless you're biotin-deficient (which is actually pretty rare), popping biotin supplements won’t make your hair grow faster or thicker overnight. Multiple studies have found that biotin supplements don’t significantly impact hair growth in healthy individuals. So while it won’t hurt you—and it's still a great nutrient—it’s not a miracle hair vitamin.

If you’re eating a balanced diet, you’re probably already getting enough biotin. So before spending big on those trendy gummies, you might want to focus on ingredients with stronger research behind them (spoiler: we’ve got a few coming up!).

Omega-3

Omega-3 and Omega-6 are essential fatty acids—meaning your body needs them but can’t make them on its own. You’ll find these healthy fats in foods like flaxseeds, chia seeds, walnuts, and fatty fish (hello, salmon!).

They’ve earned a reputation for being do-it-all nutrients: supporting brain function, muscle performance, immune health, and yep—potentially even hair growth.

You can boost your intake by eating more omega-rich foods or taking supplements (like fish oil or algae oil). But what about the hair hype?

✅ Confirmed: Omegas Can Help Your Hair—But They’re Not Magic

There’s growing research showing that omega-3 and omega-6 may help reduce hair shedding, increase density, and even improve scalp health by reducing inflammation. One study found that women who took an omega supplement for 6 months had significantly thicker hair and less hair loss compared to a control group.

So yes—these fats do have hair benefits, especially if your diet is low in healthy oils. Just remember: results won’t be instant, and omegas work best when paired with a balanced diet and good hair habits (no 5-day dry shampoo streaks, please).

Collagen

Collagen is the most abundant protein in your body, holding together everything from your skin and bones to your joints and ligaments. Naturally, collagen supplements—usually in powder, capsule, or drink form—promise to boost all the glow: skin, joints, nails, and hair.

Most collagen supplements contain hydrolyzed collagen (a.k.a. collagen peptides), which are broken down into tiny bits your body can absorb more easily. These peptides are often sourced from bovine (cow), marine (fish), or poultry (chicken) collagen.

So do they help your hair?

❌ Busted: Great for Skin, Not So Much for Hair Growth

Let’s be clear: Collagen is amazing for skin. Several studies show that collagen peptides can improve skin elasticity, hydration, and even reduce wrinkles over time. It’s also helpful for joint health and may support bone density.

But when it comes to hair growth? The evidence just isn’t there. There are currently no strong clinical studies proving that collagen supplements directly promote hair growth. While collagen provides amino acids that could support the structure of hair, it’s not the magic solution it’s often hyped up to be.

So yes—glow up your skin game with collagen if you love it, but don’t count on it to give you Rapunzel hair.

Vitamin D

You can get vitamin D from sunlight, certain foods (like salmon, egg yolks, and fortified milk), or supplements. But what about hair growth?

✅ Confirmed: Vitamin D Can Help Hair—Especially If You’re Low

Recent studies show that vitamin D plays a role in hair follicle cycling, particularly in kickstarting the anagen (growth) phase of the hair cycle. When your body doesn’t have enough of it, things can go sideways—deficiency has been linked to hair loss conditions like androgenetic alopecia and alopecia areata.

In fact, people with low vitamin D levels are more likely to experience thinning, shedding, or slowed growth. Supplementing can help, especially if you're deficient. Some studies even show that topical forms (like calcipotriol) might improve certain types of hair loss.

The science is still evolving, but one thing’s clear: if your levels are low, bringing them back to normal could help bring your hair back, too.

Your Hair Deserves Facts, Not Fads:

Here’s the deal: some ingredients (like vitamin D and omegas) do have science-backed benefits for hair growth—especially if your body’s missing them. Others (like collagen and biotin) are great for overall wellness, but won’t magically fix your hair if there’s no real deficiency.

So before you fill your cart with buzzwords, take a deep breath and remember: the best glow-up comes from a mix of good nutrition, smart habits, and knowing your body.
