Biotin has become one of the most talked-about nutrients in the world of hair and beauty. From social media influencers to supermarket shelves, it's often promoted as the secret to faster-growing, thicker and healthier hair.
But is it really that simple?
The truth is that biotin has an important role to play in maintaining healthy hair, yet many of the claims made about it go far beyond what the science supports.
At Laura Simmons, we believe in giving you honest, evidence-informed advice so you can make confident decisions about your hair and scalp.
Let's separate the facts from the myths.
What Is Biotin?
Biotin, also known as Vitamin B7, is a water-soluble B vitamin that helps the body convert food into energy.
It also plays an important role in maintaining healthy skin and hair.
Unlike fat-soluble vitamins, biotin isn't stored in large amounts within the body. Any excess is naturally excreted, which is why regular dietary intake is important.
One of the reasons biotin is so well known is because it has an authorised UK health claim.
Biotin contributes to the maintenance of normal hair and skin.
This claim is supported by scientific evidence and approved for use on food supplements within the UK.
However, it's important to understand exactly what that statement means—and just as importantly, what it doesn't.
Did You Know?
Biotin is also known as Vitamin B7 and was once referred to as Vitamin H, with the "H" coming from the German words Haar (hair) and Haut (skin). Today, Vitamin B7 is the name most commonly used in healthcare and nutrition.
Myth 1: Biotin Makes Your Hair Grow Faster
This is probably the biggest misconception surrounding biotin.
The evidence does not show that biotin makes healthy hair grow faster.
Instead, biotin contributes to the maintenance of normal hair.
Think of biotin as one of the nutrients your body needs to support normal hair health. If your body already has everything it needs, taking extra biotin won't necessarily make your hair grow more quickly.
Hair growth is influenced by many different factors, including:
- Genetics.
- Hormones.
- Overall nutrition.
- Stress.
- General health.
- The condition of your scalp.
Biotin is just one part of a much bigger picture.
Myth 2: Everyone Should Take Biotin
Not necessarily.
Most people obtain biotin naturally through a balanced diet.
Foods such as eggs, nuts, seeds, salmon, sweet potatoes and certain vegetables all contribute to your daily intake.
True biotin deficiency is relatively uncommon.
However, there are times when additional nutritional support may be beneficial.
Some people may choose to include biotin as part of their routine during periods such as:
- Menopause.
- Postpartum recovery.
- Times of prolonged physical or emotional stress.
- Restrictive or plant-based diets.
- Periods of illness or recovery.
It's important to remember that supplements are designed to complement a healthy diet—not replace it.
Myth 3: More Biotin Means Better Results
It's easy to assume that if some biotin is good, taking much more must be even better.
In reality, that's not how nutrition works.
Many hair supplements contain extremely high doses of biotin, often far above the amount most people require.
Current evidence doesn't show that taking increasingly larger doses leads to healthier or faster-growing hair in people who already have adequate biotin intake.
At Laura Simmons, we've chosen a carefully considered dose of 2,000 micrograms of biotin per daily serving.
Rather than chasing trends or promoting unnecessary megadoses, we've focused on creating a balanced formulation designed to complement a healthy lifestyle.
Myth 4: Biotin Can Cure Hair Loss
Hair loss is rarely caused by one single factor.
Although nutrition can influence hair health, there are many possible reasons why someone may experience increased shedding or thinning.
These can include:
- Hormonal changes.
- Iron deficiency or other nutritional deficiencies.
- Thyroid disorders.
- Significant emotional or physical stress.
- Certain medications.
- Illness or surgery.
- Scalp conditions.
- Genetics.
This is why it's so important not to self-diagnose.
If you've noticed sudden, excessive or persistent hair loss, it's always advisable to seek professional advice.
Your GP can investigate possible underlying medical causes and arrange blood tests where appropriate.
You may also benefit from consulting a qualified trichologist. Trichologists specialise in the health of the hair and scalp and can assess factors such as your scalp condition, hair growth patterns, lifestyle and nutritional influences.
A qualified trichologist can also work alongside your GP or other healthcare professionals where appropriate, helping to build a clearer picture of what may be contributing to your hair concerns and advising on the most suitable course of action.
Understanding the underlying cause is often the first step towards finding the right solution.
Myth 5: Biotin Works Overnight
Healthy hair takes time.
Hair grows in cycles, and the hair you see today actually began developing beneath your scalp several weeks—or even months—ago.
For that reason, nutritional changes aren't reflected immediately.
Whether you're improving your diet or introducing a supplement, consistency is far more important than expecting quick results.
Healthy habits, repeated over time, often have the greatest impact.
The Thinking Behind Our Hair Gummies
When I developed the Laura Simmons Hair Gummies, I wanted to create something that reflected the same philosophy as the rest of my range.
Not exaggerated promises.
Not miracle claims.
Just thoughtful nutritional support, backed by evidence.
Alongside biotin, our formula contains carefully selected vitamins including Vitamins A, B5, B6, B12, C, D, E, K1 and folic acid, each chosen to complement overall wellbeing and support healthy hair and skin as part of a balanced diet.
Just as importantly, I wanted to create something people would genuinely enjoy taking every day, because healthy habits are far easier to maintain when they become part of your routine rather than another task on your to-do list.
Healthy hair is built through consistency, not quick fixes.
An Important Note About Blood Tests
If you're taking any supplement containing biotin, it's important to know that biotin may temporarily interfere with certain laboratory blood tests, including some used to assess thyroid function and heart health.
Although this doesn't affect the safety of biotin itself, it can influence the accuracy of some test results.
If you're due to have blood tests, always let your healthcare professional know you're taking a supplement containing biotin.
Depending on the test being carried out, they may recommend stopping your supplement for around 48–72 hours beforehand.
Final Thoughts
Biotin is an important nutrient that contributes to the maintenance of normal hair and skin, but it's often misunderstood.
It isn't a miracle ingredient.
It won't instantly transform your hair or solve every hair concern.
Instead, it forms one part of a much bigger picture that includes good nutrition, overall health, hormones, genetics, lifestyle and, of course, the condition of your scalp.
At Laura Simmons, we believe that understanding your hair is just as important as caring for it.
Healthy hair is never about just one thing.
It's about supporting your body, caring for your scalp and making informed choices that work for you.
Because healthy hair starts with a healthy scalp.
