What is biotin?

biotin vs minoxidil

Biotin, vitamin B7 or vitamin H, is a water-soluble vitamin crucial in converting certain nutrients into energy. It's also essential for the health of your hair, skin, and nails.

Biotin is vital for maintaining healthy hair and skin, as it plays a significant role in keratin production, a protein that makes up these structures. 

Its rare deficiency can lead to hair loss, leading to the widespread use of biotin supplements to improve hair health. 

However, the effectiveness of biotin in hair growth is more pronounced in individuals with a deficiency. 

Its effectiveness remains controversial for those without a deficiency and varies from person to person. 

It's found naturally in foods like eggs, almonds, cauliflower, cheese, mushrooms, sweet potatoes, and spinach. 

Biotin supplements are also widely available for those who need more through their diet. However, before starting any supplement regimen, it's recommended to consult a healthcare provider.

How does biotin work?

Biotin helps with hair loss by playing a vital role in producing keratin, the primary protein that makes up hair. When you have enough biotin in your body, it can support the health and strength of your hair, potentially preventing it from falling out or breaking. 

However, biotin's effectiveness in treating hair loss is more evident in individuals with biotin deficiency. 

It's important to note that while biotin can support hair health, it's not a cure-all for all types of hair loss, especially those caused by genetic factors or other underlying health conditions.

Benefits of biotin

Here are the benefits of Biotin:

  • Promotes hair growth: Biotin is often associated with increased hair growth and thickness, making it a popular supplement for those with thinning hair.
  • Strengthens nails: It helps enhance nail strength, reducing brittleness and breakage.
  • Improves skin health: Biotin supports healthy skin by aiding in the metabolism of fats, proteins, and carbohydrates, improving skin texture and appearance.
  • Boosts metabolism: It plays a vital role in the metabolism of proteins, fats, and carbohydrates, aiding overall energy production.
  • Supports nervous system: Biotin is involved in neurotransmitter function, which helps to maintain proper nervous system functioning.
  • Aids in pregnancy and nreastfeeding: Essential for embryonic growth, biotin supplementation is often recommended during pregnancy and breastfeeding.
  • Helps in blood sugar regulation: Some studies suggest that biotin may help regulate blood sugar levels, particularly in diabetics.
  • Enhances cognitive function: It may support cognitive function by playing a part in synthesizing fatty acids essential for brain health.
  • Easily accessible: Found naturally in a wide range of foods like eggs, nuts, and whole grains, making it easy to incorporate into your diet.

Side effects of biotin

Biotin can have side effects like any supplement, although they are relatively rare. Not everyone experiences these side effects, typically associated with high doses. 

Here are some possible side effects to be aware of:

  • Skin rashes: Some people may experience skin rashes, particularly on the face and body.
  • Digestive issues: Biotin can cause stomach cramps, diarrhoea, or nausea in some individuals.
  • Potential interaction with lab tests: High doses of biotin can interfere with specific laboratory tests, leading to falsely high or low results. These include tests for heart problems, thyroid disorders, and iron deficiency anaemia.
  • Allergic reactions: Although rare, some individuals may experience an allergic reaction to biotin, resulting in symptoms like itching, swelling, and respiratory problems.

What is Minoxidil?

biotin vs minoxidil

Minoxidil or Rogaine is a topical treatment widely used to combat hair loss and promote hair regrowth. Initially developed as a medication for high blood pressure, it was discovered that one of its side effects was unexpected hair growth. 

Today, it's one of the most popular over-the-counter products for addressing hair loss, available in different strengths, and used by millions worldwide.

Minoxidil works by prolonging the growth phase of hair follicles, thus promoting the growth of more hair strands and slowing down hair loss. 

It is applied directly to the scalp, typically twice a day, and has shown effectiveness for both men and women. 

While it doesn't cure baldness, it has been proven to help slow its progression and even regrow some hair in some instances.

How does minoxidil work?

Minoxidil, or Rogaine, works by helping to increase blood flow to the areas of application, typically the scalp. This is believed to extend the hair follicle cycle's anagen phase (or growth phase), leading to longer, thicker hair strands. Additionally, it may increase the hair follicle's size, resulting in thicker hair. 

By stimulating these changes, minoxidil helps slow or stop hair loss and can promote hair regrowth in individuals suffering from pattern baldness or thinning hair.

Benefits of minoxidil

Here are the benefits of Minoxidil, presented in bullet points:

  • Stimulates hair growth: Minoxidil is clinically proven to stimulate hair growth, particularly in individuals with pattern baldness.
  • Slows hair loss: It can significantly slow the process of hair thinning and loss by prolonging the growth phase of hair follicles.
  • Works for both men and women: Minoxidil is available in formulations suitable for men and women, catering to different needs and hair types.
  • Easy to apply: Minoxidil is typically easy to apply to the scalp in topical solutions like foam or liquid.
  • Over-the-counter availability: Minoxidil can be purchased without a prescription in many places, unlike some hair growth treatments.
  • May improve hair density: Regular use can increase hair density and fullness, improving the overall appearance of the hair.
  • Fast-acting: Users often report seeing positive changes in hair growth within a few months of consistent use.
  • Can be used with other hair treatments: Minoxidil can be used with other hair care products or treatments, enhancing its effectiveness.
  • Proven track record: Minoxidil has a well-established reputation in the hair care industry, with decades of use and research backing its effectiveness.

Side effects of minoxidil

Here are a few side effects of Minoxidil, irrespective of its brand name. 

  • Local irritation: This is one of the most common side effects, resulting in itching, redness, flaking, or a burning/tingling sensation at the application site. The tingling might result from increased blood flow due to the medication.
  • Allergic contact dermatitis: Some users may experience an allergic reaction, which can cause similar symptoms to local irritation, including itching, redness, and flaking.
  • Anaphylaxis: This is a rare but severe allergic reaction that can cause symptoms like hives, a full-body rash, nausea, vomiting, and swelling of the lips, tongue, throat, or mouth. If these symptoms occur, stopping using the product and seeking emergency medical care immediately is crucial.
  • Increased shedding: Often experienced when starting treatment, this is sometimes referred to as 'minoxidil shedding' or 'dread shed.' This phenomenon occurs as inactive hair follicles shed their existing hair for new, healthier growth.

Biotin vs minoxidil: What are the differences?

Biotin and Minoxidil are prominent solutions in hair care, but they operate in distinct ways and cater to different needs.

The differences between these two can be outlined in more detail as follows:

Source and composition

Biotin is a natural B vitamin found in various food items and supplements, whereas Minoxidil is a synthesized medication primarily designed to treat hair loss.

Primary function

Mode of application

Biotin vs Minoxidil: Which one is better for you?
