What Vitamins Are Good for Hair Growth (and Why Gut Health Matters More Than You Think)

The Real Story Behind Hair Growth – and Why It Starts Deeper Than You Think

Walk down any beauty aisle or scroll through TikTok, and you’ll find thousands of products promising longer, thicker, shinier hair. Caffeine shampoos, biotin gummies, rosemary oil, scalp serums, you name it. But for many women, the struggle runs deeper. Hair loss, thinning, or breakage can quietly chip away at confidence, especially when it feels like nothing truly works.

That was exactly the reality for Carley Jones, a Manchester-based entrepreneur and co-founder of Boombiotics. After years of running successful beauty ventures and working alongside her wife, Ciara, a professional hair stylist, Carley faced something that no amount of salon expertise could prepare her for: postpartum and IVF-related hair loss.

“I’d always been confident about my hair,” Carley has said. “Then suddenly, after IVF and having my baby, I was dealing with thinning patches, dullness, and breakage. It sounds vain, but it really hit my self-esteem. I didn’t feel like myself anymore.”

As salon owners, Carley and Ciara weren’t strangers to the problem. They saw women every week, new mums, clients going through menopause, people recovering from illness, each asking the same question: “Why is my hair so thin, and how do I fix it?”

Carley’s experience, though deeply personal, was far from unique. It became the spark that started Boombiotics, a company that would go on to redefine the way we think about hair growth, not as a surface-level issue, but as something that begins within the body itself.

The Gut–Hair Connection Nobody Talks About

Most people associate hair growth with biotin or keratin. Those matter, of course, but there’s an often-overlooked player in the mix: the gut microbiome.

Emerging research shows that gut health plays a key role in how our bodies absorb nutrients, especially those essential for healthy hair, skin, and nails. When your gut is out of balance, it doesn’t matter how many vitamins you take. Your body simply can’t absorb them properly.

That’s where the Boombiotics philosophy began to take shape. Carley and Ciara spent years working with labs during the lockdown, testing and retesting formulations to find a way to support hair health from the inside out.

Their discovery was simple but groundbreaking:

“It’s pointless taking hair growth vitamins if your gut isn’t absorbing them.”

That understanding led to the creation of HELPGUT®, a proprietary blend of six probiotic strains designed specifically to support gut health and nutrient absorption, essential for hair growth. This became the foundation of the Boombiotics 5-Piece Hair Growth Kit, a complete system that targets every layer of the problem: scalp, strands, and the gut.

What Vitamins Actually Matter for Hair Growth

So, let’s get practical. If you’ve ever asked “What vitamins are good for hair growth?”, you’re not alone. Here’s what the science (and the Boombiotics formulation) tells us.

1. Biotin (Vitamin B7)

Biotin is probably the most well-known hair vitamin, and for good reason. It helps the body produce keratin, the protein that makes up hair. A deficiency can lead to brittle strands and thinning over time. Boombiotics includes biotin in their Advanced++ Hair Growth Vitamin, but importantly, it’s paired with probiotics to help the body actually use it.

2. Zinc

Zinc supports hair follicle health and helps balance hormones that can contribute to hair loss. It’s especially important for postpartum recovery, where hormonal shifts are intense.

3. Vitamin C and E

These antioxidants help protect hair follicles from oxidative stress and environmental damage. They also support collagen production, which strengthens the hair shaft and improves elasticity.

4. Vitamin D

Low Vitamin D levels are linked with hair loss, particularly in women. Boombiotics’ internal formula ensures this key vitamin is delivered in a way that’s easily absorbed and gut-friendly.

5. Probiotics (HELPGUT® blend)

This is where Boombiotics stands apart. The six carefully chosen probiotic strains in Boombiotics Advanced++ Hair Growth Supplement help maintain a healthy gut microbiome, ensuring better absorption of all the above nutrients.

Because here’s the truth: you can have the best vitamins in the world, but if your gut isn’t healthy, your hair won’t see the benefits.

The Science Behind the Shine

Boombiotics didn’t stop at supplements. Their 5-piece system combines internal and external care, something most brands overlook. Each step plays a role in the bigger picture:

• Hair Growth Shampoo: Gently cleanses and stimulates the scalp without sulfates or silicones.
  

• Conditioner: Uses proteins from rice and wheat to repair and strengthen.
  

• Hair Mask: Deeply nourishes and restores moisture.
  

• Scalp Oil: Enriched with rosemary and argan oil to promote circulation and hydration.
  

• HELPGUT® Hair Growth Vitamin: Supports the internal foundation for healthy growth.
  

The result is what Carley calls “360° haircare, powered by your gut.”

Boombiotics uses natural alternatives to harsh chemicals, Lauryl Glucoside instead of Sodium Lauryl Sulfate, for example, proving that clean formulations don’t have to compromise on performance. The products are vegan, cruelty-free, and made with over 95% naturally derived ingredients.

FAQs: 

1. Why is my hair thinning, and how do I know if it’s from stress, hormones, or nutrition?

Hair thinning can happen for a mix of reasons, which is why it’s often so frustrating. For many women, it’s a combination of hormonal changes (like postpartum or menopause), stress, and nutritional deficiencies that affect the hair growth cycle. When the body is under stress, physical or emotional, it prioritises essential functions over hair growth.

What makes this worse is that stress and hormones also disrupt the gut microbiome, where nutrients are absorbed. If your gut is inflamed or imbalanced, even a healthy diet might not be enough to feed your follicles.

This is exactly why Boombiotics focuses on the gut–hair connection. The brand’s probiotic-powered HELPGUT® blend helps restore the gut environment, so the vitamins you take actually reach the hair follicles where they’re needed.

If your hair feels thin or fragile and you’re also dealing with bloating, fatigue, or skin issues, it’s a sign your body might need internal support as well as topical care.

2. What vitamins should I actually take for hair growth?

It’s tempting to throw every “hair vitamin” on the shelf into your routine, but balance matters more than quantity. According to research and Boombiotics’ own formulations, the most effective nutrients for hair growth include:

• Biotin (Vitamin B7): Promotes keratin production, which strengthens hair strands.
  

• Zinc: Supports scalp health and regulates oil glands.
  

• Vitamin D: Encourages the activation of hair follicles.
  

• Vitamin C & E: Protect against oxidative stress and environmental damage.
  

• Probiotics: Help your gut absorb all the above efficiently.
  

The Boombiotics Advanced++ Hair Growth Vitamin combines these essentials with the HELPGUT® probiotic blend, ensuring you’re not just taking vitamins, you’re absorbing them.

3. How long does it take to see results from hair growth vitamins?

Hair growth is a slow biological process. Even under perfect conditions, hair only grows about 1 cm per month, so expecting visible results in a few weeks is unrealistic.

Most Boombiotics customers report noticing changes in 8 to 12 weeks, starting with reduced shedding and stronger texture, followed by new baby hairs and thicker strands.

Carley Jones, Boombiotics’ founder, is upfront about this:

“We don’t promise overnight miracles. Hair growth takes consistency, patience, and internal balance. The goal is to build a foundation that lasts.”

To get the best results, Boombiotics recommends committing to a 90-day routine using the full 5-Piece Hair Growth Kit, which supports the scalp, strands, and gut together.

4. I’ve tried biotin before and it didn’t work. What makes Boombiotics different?

This is one of the most common frustrations. Biotin is a fantastic nutrient, but it only helps if your body can absorb and utilise it. If your gut is out of balance, because of stress, antibiotics, or diet, your system may not process biotin efficiently, meaning your hair doesn’t get the benefit.

Boombiotics tackles that head-on with HELPGUT® probiotics, which improve nutrient absorption and support healthy digestion. The brand’s approach is 360° haircare, so you’re not just treating symptoms at the scalp level, you’re solving the root cause internally.

That’s what sets Boombiotics apart from the typical single-ingredient biotin supplements or caffeine shampoos that don’t address gut health.

5. Can Boombiotics help with postpartum hair loss?

A post shared by Boombiotics LTD (@boombiotics)

Yes, and that’s actually how Boombiotics began. Carley Jones experienced postpartum and IVF-related hair loss herself, and the products were formulated with this in mind.

Postpartum hair shedding happens because estrogen levels drop sharply after childbirth. The follicles shift from the growth phase (anagen) to the shedding phase (telogen), and the result is sudden thinning, especially around the hairline.

The Boombiotics routine supports recovery on multiple fronts:

• The HELPGUT® probiotics rebalance digestion and hormone metabolism.
  

• The Hair Growth Vitamin provides biotin, zinc, and D3 for healthy follicle function.
  

• The Scalp Oil and Shampoo help re-energise the scalp and stimulate regrowth.
  

Women using the Boombiotics Hair Growth Kit often describe it as “getting their confidence back, one wash at a time.”

6. Does Boombiotics help men with thinning hair too?

Absolutely. While Boombiotics was founded by women and designed with female hair cycles in mind, the underlying science, gut health, nutrient absorption, and follicle stimulation, applies to everyone.

Many men use Boombiotics products for early-stage thinning or to support hair thickening around the crown and hairline. The brand’s Hair Growth Vitamin and Scalp Oil are unisex and formulated without synthetic fragrance or heavy silicones, making them safe for sensitive skin and daily use.

For men experiencing stress-related shedding or nutrition gaps, the probiotic element can make a significant difference over time.

7. Are Boombiotics products safe for sensitive scalps or coloured hair?

Yes. All Boombiotics products are dermatologically tested, vegan, and cruelty-free, made with over 95% naturally derived ingredients.

The formulations avoid harsh sulfates and silicones that can strip or coat the hair. Instead, they use gentle cleansers like Lauryl Glucoside and hydrating botanicals like rosemary, castor, and argan oils, which help soothe irritation and improve scalp health.

Coloured and chemically treated hair benefits too, since these ingredients strengthen the hair fibre without fading colour or weighing it down.

8. Can I use Boombiotics alongside my existing hair routine or medical treatments?

In most cases, yes. Boombiotics products are designed to complement, not compete with, other treatments. If you’re using a prescription medication or topical like minoxidil, you can still incorporate Boombiotics for internal and scalp support.

That said, if you’re dealing with a medical condition such as alopecia areata or thyroid-related hair loss, it’s always best to consult your GP or dermatologist before making major changes.

The key idea is synergy: the better your gut and scalp environment, the more effectively other treatments can work.

9. How does gut health actually affect hair? It sounds a bit far-fetched.

It might sound new, but the science is solid. Your gut is where most nutrient absorption takes place. If the microbiome is unbalanced, say, from antibiotics, poor diet, or chronic stress, it can lead to inflammation that blocks nutrient uptake.

Essential hair vitamins like biotin, zinc, and vitamin D rely on gut health to be processed and delivered to hair follicles. A damaged gut lining can mean your hair simply isn’t getting what it needs, no matter how many supplements you take.

The probiotics in Boombiotics’ HELPGUT® blend were chosen specifically for this purpose. They help restore a healthy gut barrier, improve digestion, and ensure that the nutrients in your food and supplements are absorbed efficiently.

So yes, it’s not just a marketing line. It’s biology.

10. What’s the best way to start with Boombiotics if I’ve never tried hair growth products before?

If you’re new to hair growth routines, start simple and consistent:

1. Begin with the Boombiotics 5-Piece Hair Growth Kit – this gives you everything you need in one system (shampoo, conditioner, hair mask, scalp oil, and HELPGUT® Hair Growth Vitamin).
   

2. Use the shampoo and conditioner 2–3 times a week.
   

3. Apply the scalp oil a few hours before washing, or leave overnight for deep nourishment.
   

4. Take the vitamin daily with food.
   

5. Track your progress for 90 days.
   

It’s about creating a ritual, not a quick fix. Hair growth is cumulative, each wash, each dose builds on the last.

11. Are natural oils like rosemary or castor oil really effective for hair growth?

Yes, when used correctly. Both rosemary and castor oil have been shown to support circulation and nourish the scalp. Boombiotics includes these in their Hair Growth Oil, but the key is balance.

Pure oils can sometimes clog follicles if used too heavily. The Boombiotics formulation blends these oils with lighter carriers and scalp-friendly ingredients to make them effective without greasiness or buildup.

It’s one of the most popular products in the range, especially for edges and thinning patches, an area where many people see early results.

12. What makes Boombiotics worth the investment compared to cheaper hair vitamins?

The short answer is: science, synergy, and transparency.

Boombiotics isn’t just a supplement or a shampoo, it’s a complete ecosystem for hair health. The products were built to work together, internally and externally, using ingredients that are clinically researched and ethically sourced.

Cheaper products might contain high doses of biotin or caffeine but lack the probiotic support needed to make those nutrients effective. Boombiotics bridges that gap with the HELPGUT® blend, high-quality vitamins, and clean formulations that are safe for long-term use.

As Carley puts it:

“We built Boombiotics out of frustration. I wanted something that actually worked, not something that looked good on a shelf.”
