The Best Nutrients for Lash Growth

So what does it really take to become an ultimate lash retention guardian for your clients? Killer isolation and lightning-fast adhesive are great allies but there is more to it. Spoiler alert: what’s happening beneath the lash line contributes to retention as well. Yup, we’re talking about lash health from the inside out.

Sometimes, you feel like you’re doing everything right, but the issue remains. Premature shedding gets on the way, natural lashes are weak, and your client is sad about being ghosted by extensions. (No crush can hurt us as much as our lashes). But here’s the tea: sometimes the root of the problem is literally at the root.

When clients understand what stimulates lash growth from within, they get better results, you get happier clients, and everyone wins. So let’s break down what is good for eyelash growth, which vitamins actually work, how to keep lashes healthy and how you can set your clients on the right track.

How Overall Health Affects Eyelash Growth

Just like the hair on the head, natural lashes go through a growth cycle:

· Anagen (growth phase) – the glow-up stage

· Catagen (transition phase) – the awkward middle school phase

· Telogen (resting/shedding phase) – the “I need a break” era

Thing is, if your client’s body is stressed, sleep-deprived, or running on microwave dinners and cold brew, that cycle can go totally out of control. Lashes may peace out early or take forever to grow back. Who would even want that?

That’s why taking care of lashes on a deep level is just as important as keeping them clean. When your client’s nutrition, mood, and overall health are on point, their lashes are more likely to grow strong, stay put, and hold those gorgeous extensions like champs.

What Vitamins Are Good For Eyelash Growth

So your client hits you with, “what vitamins help eyelashes grow?” Let’s get into your vitamin cheat sheet:

1. Biotin (Vitamin B7): The Lash World’s Ride-or-Die

Does biotin help with eyelash growth? Biotin is basically the A-list celebrity of the hair growth world. It’s essential for producing keratin, aka the protein that lashes are made of.

· It helps lashes grow thicker, stronger, and faster.

· Deficiency = weak, brittle lashes that bail early.

· Found in eggs, salmon, sweet potatoes, and supplement form.

Hot tip: If a client’s lashes are always snapping or falling out too soon, biotin for eyelashes might be the boost they need.

2. Vitamin E: The Bodyguard for Your Lash Follicles

Vitamin E is like the bouncer at the club — it protects lash follicles from the oxidative drama that can cause hair loss.

· Improves blood flow to the lash line.

· Keeps follicles hydrated and healthy.

· Found in almonds, sunflower seeds, spinach, and skincare products.

Want to give clients a quick win? Suggest a lash serum with Vitamin E for eyelashes or recommend they toss some avocados into their smoothies.

3. Vitamin C: The Collagen Queen

Vitamin C isn’t just for cold season — it plays a major role in keeping lashes lush by supporting collagen production.

· Collagen strengthens the skin and follicles around the lash line.

· Also fights off those pesky free radicals.

· Found in oranges, strawberries, bell peppers, and skincare serums.

Bonus points: Vitamin C makes other nutrients (like iron) work better, so it’s a total team player.

4. Vitamin A: The Growth Cycle Regulator

If lash growth had a CEO, it would be Vitamin A. It keeps skin cells regenerating and follicles functioning like a well-oiled machine.

· Helps maintain a healthy lash growth cycle.

· Prevents lash thinning and sluggish regrowth.

· Found in carrots, kale, sweet potatoes, and dairy.

Pro tip: too much vitamin A can actually backfire — so remind clients not to go overboard with supplements.

5. Iron & Zinc: The Dynamic Duo

These two don’t get the spotlight as much, but they’re major players in the hair game.

· Iron brings oxygen to hair follicles. Low iron = lash fallout.

· Zinc helps with cell repair and keeps oil glands in check so follicles don’t get clogged.

Pro tip: Iron deficiency is super common, especially in women — so if a client’s lashes keep ghosting early, it might be time to get those iron levels checked.

6. Omega-3 Fatty Acids: The Inflammation Fighters

Okay, not a vitamin, but still a lash essential. Omega-3s reduce inflammation and help create the perfect lash-growing environment.

· Found in fatty fish (like salmon), chia seeds, walnuts, and flaxseed oil.

· Can also help reduce lash line dryness and irritation.

Nutrition Meets Lash Care: A Double Threat

Healthy eyelashes aren’t just built in the kitchen — they need TLC on the outside, too. Here’s the glow-up combo your clients should be doing:

- Cleanse daily with a gentle lash-safe cleanser to remove makeup, oil, and buildup. No one wants crusty lashes.

- Use a lash serum with nourishing ingredients like peptides, biotin, or panthenol to strengthen and stimulate.

- Sleep on silk pillowcases to reduce lash friction. (Also, you’ll feel like a Disney princess, so it’s a win-win.)

- Ditch the oily products around the eyes — they break down lash adhesive like it’s their full-time job.

How Lash Artists Can Use This Info Like a Boss

If you’re a lash pro, here’s your cue to go full expert mode:

Educate your clients. When you notice breakage, retention issues, or thinning lashes, don’t just shrug. Talk about nutrition, stress, and self-care habits. Be the lash whisperer they didn’t know they needed.

Recommend smartly. If a client is open to supplements, suggest a high-quality biotin or hair/skin/nails blend — but remind them to check with a doctor first. You’re a lash artist, not a pharmacist.

Post it! Use your Stories or client aftercare cards to share lash health tips. Clients love value, and showing you care beyond the glue builds massive loyalty.

Be real. Sometimes client’s lashes aren’t ready for that mega volume set, and that’s okay. Frame it as a lash growth journey — you’ll get there together.

Wrapping It Up: Healthy Lashes, Happy Clients

At the end of the day, your sets are only as strong as the lashes they sit on. When you know what vitamins boost eyelash growth — and you pass that knowledge on to your clients — you’re not just doing lashes. You’re creating confident, informed beauty lovers who see you as their go-to lash guru.

Vitamins for eyelash growth actually help, these nutrients aren’t just buzzwords — they’re the secret sauce to longer retention, fuller lash lines, and clients who come back month after month.

So next time someone asks, “How do I get my lashes to grow?” don’t just recommend a lash serum for growth. Hand them the whole lash bible — and let them know it starts on the inside.

Because when lashes are healthy, retention is better. When retention is better, clients are happier. And when clients are happier… well, you just became closer to building a lash empire, babe.
