Why Does Hair Fall Out? The Role of Biotin and Gut Microflora

Shine, density, and strength of hair depend not only on shampoos and masks. The problem often starts from within — with an imbalance of vitamins and gut microflora.
This article explains why biotin and microflora play a crucial role in maintaining healthy hair and how Zafacol IQ from Vorwarts Pharma can help.

Biotin — the “Beauty Vitamin”

Biotin (vitamin B7) belongs to the B-complex group and participates in many metabolic processes. It’s often called the “beauty vitamin” because it:

• participates in keratin synthesis — the main hair protein;
• helps maintain elasticity and integrity of hair structure;
• supports a healthy scalp;
• helps reduce hair brittleness.

However, even if biotin intake is sufficient, hair may still remain weak. The reason lies in how well the vitamin is absorbed by the body.

Why the Body Might Not Absorb Biotin

Biotin is partially synthesized by beneficial gut bacteria. If the gut microflora is disrupted, the amount of “natural” biotin decreases. This can occur due to:

• prolonged use of antibiotics;
• unbalanced diet;
• frequent stress;
• chronic digestive disorders;
• hereditary metabolic features.

How Stress and Diet Affect Biotin

Stress weakens the intestinal barrier and alters the composition of microflora, while low-fiber diets deprive bacteria of the “fuel” they need to produce biotin.

Signs of Possible Biotin Deficiency

• increased hair loss or brittleness;
• dry or oily scalp;
• weak nails;
• fatigue and irritability;
• digestive issues.

If several of these symptoms are present, it’s important to pay attention to gut health — that’s where vitamin absorption begins.

How to Support Gut Microflora

For biotin to be effectively absorbed, it’s essential to restore the natural balance of microbiota. This can be achieved through a wholesome diet, sufficient fiber, and dietary supplements that help maintain gut health.

The Role of Probiotics and Prebiotics

A combination of probiotic cultures and nutrients for them (prebiotics) helps preserve beneficial bacteria essential for biotin synthesis.

Zafacol IQ — Support from Within

Zafacol IQ from Vorwarts Pharma is a dietary supplement for adults and children aged 12+, containing a combination of butyric acid, vitamin D₃, prebiotics, and probiotics that help:

• support normal gut function;
• balance the composition of microbiota;
• reduce intestinal discomfort;
• maintain regular bowel movements.

A balanced microflora helps the body better absorb nutrients such as biotin, zinc, and iron — key elements for healthy hair.

How to Reduce Hair Loss: Quick Checklist

• Balance your diet — include foods rich in B vitamins.
• Maintain gut microbiota balance.
• Avoid excessive stress.
• Get regular sleep and rest.
• Use gentle, high-quality hair care products.

FAQ

Does biotin help with hair loss?
Yes. Biotin participates in keratin synthesis — the protein that makes up hair. Adequate levels support healthy hair, though effectiveness depends on gut health.

How to naturally support gut microflora?
Follow a balanced diet, reduce sugar intake, and add more vegetables and fiber-rich foods.

When should you consider biotin supplements?
If your hair becomes brittle and your gut microflora is disrupted after antibiotics or stress, dietary supplements can help restore balance.

Hair condition reflects the body’s internal balance. When the gut works harmoniously, biotin and micronutrients are better absorbed, making hair strong and naturally shiny.
