Natural influences on hair growth
Hair growth is influenced by many natural factors. These include genetics, hormones and environmental influences. Let’s take a closer look at these influences.
Genetic basics
Genetics and hair growth are closely linked. Our genes determine how many hair follicles we have and how quickly they grow. On average, there are around 100,000 hair follicles on the scalp.
The growth rate varies between 0.3 and 0.5 millimeters per day. This means that hair grows between 1 and 1.5 centimeters per month.
Hormonal control
Hormones have a major influence on hair growth. Testosterone, for example, promotes growth. This is why men’s hair often grows faster than women’s hair.
Hormonal fluctuations can influence hair growth. They can even lead to hair loss. Stress can cause up to 70% of hair to fall out.
Seasons and daily rhythm
The seasons also play a role in hair growth. Hair tends to grow faster in summer. This is due to better nutrition and more sunlight.
The daily rhythm also influences hair growth. The growth phase, also known as the anagen phase, lasts between two and seven years.
| Factor | Influence on hair growth |
|---|---|
| Genetics | Determines the number of hair follicles and growth rate |
| Hormones | Testosterone promotes growth |
| Seasons | Faster growth in summer |
| Daily rhythm | Influences growth phases |
Optimal nutrient supply for healthy hair
A balanced diet is important for strong hair. Proteins, vitamins and minerals are crucial for hair health.
Hair is mainly made up of keratin, a protein. A diet rich in protein helps hair growth. Lean meat, fish, eggs and pulses are good sources.
Biotin, also known as vitamin B7, strengthens the hair follicles. It promotes healthy hair growth.
Vitamins for hair are very important. Vitamins A, C and E help the scalp. Iron is also important for transporting oxygen to the hair follicles.
Spinach, lentils and whole grain products are good sources of iron. Omega-3 fatty acids nourish the scalp and hair follicles. Oily fish, chia seeds and linseed are rich in omega-3.
Avoid too much sugar, processed foods and alcohol. They can interfere with hair growth.
Food supplements such as Glowwa provide important nutrients for hair. They contain vitamins, minerals and amino acids. These strengthen the hair follicles and protect against oxidative stress.
Care and protection of the scalp

Measures to promote blood circulation

Brushing with natural bristles stimulates the scalp. It distributes natural oils.
Correct cleansing and care routine

Rinse thoroughly and treat the lengths of your hair with a conditioner.
Natural care products
