Spirulina is a blue-green micro-algae that is full of nutrients beneficial to health, including hair health. It is increasingly popular as a dietary supplement due to its many benefits for the body. In this article, we’ll explore the connection between spirulina and hair health in detail, highlighting the key nutrients found in this algae and reviewing the scientific evidence that supports its effects on hair.
What is spirulina?
Spirulina is an edible cyanobacteria that thrives in alkaline and brackish waters. It is widely recognized for its exceptional nutritional density. The Aztecs already used it as a food source centuries ago due to its richness in protein, vitamins (especially vitamin B12) and essential minerals like iron and magnesium.
Key nutrients for hair health
Proteins
Protein is essential for hair growth and repair. Spirulina is approximately 60-70% protein, making it an excellent source for promoting hair strength and vitality.
B vitamins
B vitamins , such as vitamin B12, folate (vitamin B9), and biotin (vitamin B7), found abundantly in spirulina, are crucial for maintaining healthy hair. Biotin, in particular, is known to stimulate hair growth and prevent brittleness.
Iron
Iron is essential for transporting oxygen to hair follicles. Iron deficiency can lead to hair loss. Spirulina, rich in bioavailable iron, helps maintain healthy levels of this vital element.
Amino acids
Spirulina contains all the essential amino acids , including cysteine, methionine and lysine. These amino acids promote hair growth by strengthening follicles and improving hair structure.
The effects of spirulina on hair
Several scientific studies have explored the potential effects of spirulina on hair health. A study published in the Journal of Clinical and Diagnostic Research found that spirulina supplementation improved hair density and reduced hair loss in subjects with alopecia.
Another research, published in the Journal of Applied Phycology, showed that spirulina extracts had a protective effect on hair against free radical and UV damage.
How to integrate spirulina into your hair routine
To benefit from the benefits of spirulina on your hair, you can incorporate it into your diet in the form of powder, tablets or capsules. It is recommended to consult a healthcare professional before starting any supplementation.
Additionally, you can also use hair products containing spirulina. Many shampoos and hair masks use spirulina for its nourishing and conditioning properties.
To conclude, spirulina has many benefits for hair health due to its richness in protein, B vitamins, iron and amino acids. Studies show that spirulina can promote hair growth, reduce hair loss, and protect against environmental damage. By incorporating spirulina into your diet and hair routine, you can contribute to stronger, thicker, healthier hair.
