Das kann Biotin für deine Haare tun

What biotin can do for your hair

by Pia Wolter on Jul 30 2025

The German word "Haarpracht" (luxurious hair) says it all: The importance of healthy hair should not be underestimated. Our hair has a great influence on our self-perception and how we are perceived by others. Self-confidence is important, but hair also reflects your general state of health and your diet.

An adequate supply of certain vitamins and nutrients influences the appearance of the hair, which absorbs everything through your scalp. The hair follicles, from which the hair root emerges, grow for two to six years in the anagen phase of hair regeneration until they reach their maximum possible length. When the hair then falls out, the hair follicle regenerates and new hair grows.

During this growth phase, the hair root can be effectively nourished through the scalp, but some nutrient deficiencies can also negatively affect the hairstyle. Especially with a biotin deficiency, certain hair problems can occur. You can easily recognize biotin deficiency by brittle strands or noticeable hair loss.

Hair Loss

Hair loss is a widespread problem that can have many causes and is also divided into different types. These include genetically caused hair loss, but also circular hair loss (alopecia areata) and diffuse hair loss (alopecia diffusa).

Possible reasons if you suddenly lose hair out of nowhere can be:

  • Hormonal changes
  • Everyday stress
  • Unbalanced diet
  • Medication and illnesses

In the event of certain nutrient deficiencies, you can stimulate hair growth by supporting your body with certain building blocks like biotin to counteract biotin deficiency.

Thin Hair

Thin hair can be natural for you or develop over time. Common causes here are also hormonal changes, genetic predisposition, or nutrient deficiencies. Sometimes a shampoo can make hair drier and thus lead to breakage.

Environmental factors and frequent hair treatments such as coloring or heat styling can particularly weaken the hair structure. At this point, good heat protection and reducing strenuous hair treatments help.

The disadvantages are obvious: Thin hair often looks lifeless and dull, is more prone to breakage, and is harder to style due to a lack of volume. Especially with fine strands, the impression of hair loss or thinning areas can arise. Here you will find four hairstyles for thin hair - if you want denser, full growth, you can effectively promote your volume with a hair serum that contains biotin, for example.

What is Biotin?

The importance of this active ingredient is already revealed in its name: The name biotin is derived from the Greek word "bios" (life). Biotin is also known as vitamin B7 or vitamin H (when discovered by Steinitz, the H stood for skin). It is an important nutrient for skin, nails, and hair. The vitamin ensures the conversion of nutrients into energy in our body and is an important building block for the body's own production of keratin.

Biotin-Containing Products

A balanced nutrient intake is crucial for beautiful hair growth. Biotin plays a central role in this. It supports the formation of keratin, the main component of hair, and thus promotes hair strength and health.

Dietary supplements containing biotin can help strengthen the structure and reduce hair loss – especially if it is caused by nutrient deficiencies. Regular intake of biotin can help support hair growth and make it more resistant to external influences. This way, the foundation for nourished hair can be laid naturally.

Biotin in Foods

Biotin is found in many foods, but usually only in the single-digit microgram range. Animal products such as offal like beef liver, but also egg yolk and many dairy products, are particularly rich in biotin. Bananas, vegetables like spinach, and chanterelles also contain biotin. In addition, foods like yeast, many plant-based products like whole grain rice, oatmeal, walnuts, and soybeans contain biotin, which are also good for skin and nails.

Hair Serum

A friend recently asked me if a serum is actually effective. The effectiveness of products like hair serum usually lies in the regularity of application and the dosage of the ingredients: With regular use, a good, highly concentrated serum like the FullHair Serum from Dr. Massing can promote hair growth and thicken bald spots on the scalp. At the same time, serums can intensely nourish your scalp and prevent it from becoming dry.

The hair serum contains growth agents, zinc, and caffeine in addition to biotin. These ingredients give the serum its strengthening and growth-promoting effect. Additionally, the keratin in the serum ensures an improved hair structure. If a serum is not enough for you, you can also take capsules in addition to the hair serum.

How Hair Capsules Can Help

The effectiveness of creams or shampoos containing biotin can be doubted, as the body can hardly absorb biotin externally, and a hair serum is only effective due to its high dosage. Our FullHair Hair Capsules: beautiful hair with biotin and vitamins provide support from within with additional biotin. In contrast to biotin-containing foods, the content of the ingredient in a capsule is high enough to cover the daily requirement. This strengthens the effect of biotin, so you can feel and see the difference in your hair after just a few weeks. In addition to biotin, each capsule contains zinc, selenium, and copper.

Dr. Massing's Recommendation

Biotin-supported hair growth is less prone to damage and split ends, and those who pay attention to proper care do something good for their hair and at the same time feel better.

Stronger hair reflects your general state of health and influences self-confidence. For radiant, full hair, a good supply of vitamins and nutrients is crucial. Nutrient deficiencies – especially biotin deficiency – can lead to dry strands, split ends, and hair loss.

Biotin is essential for the production of keratin, the main component of hair. It promotes hair strength and helps reduce hair problems. Biotin supplements can improve growth and health, primarily in cases of nutrient deficiency.

Because biotin can only be absorbed to a limited extent through cream or shampoo, dietary supplements remain an effective solution for strengthening hair from within. Full hair thanks to effective biotin absorption works wonders. As an alternative, a high-quality hair serum promises good results - you can recognize the quality of the serum by the biotin dosage. But whether hair serum or hair capsules, it is important to supply your body with the necessary nutrients to strengthen skin, hair, and nails.

Now you know how important biotin is!

All the best,
