Biotin rich foods and supplements are frequently cited as an excellent way to improve hair health and increase hair growth. Biotin is not only great for your hair, it’s also extremely beneficial in other areas of health and in fact crucial for some key biological processes in the human body. Increasing your in take of biotin may be the key step needed to improve your hair health.
Biotin is a type of B-vitamin produced naturally by “good” gastrointestinal bacteria. It is also known as “vitamin H” and has numerous health benefits. While biotin deficiency is quite rare as this nutrient is produced by your body, increasing your biotin intake by including supplements in your diet can help you grow hair faster.
Biotin interacts with certain enzymes and helps produce amino acids. Amino acids build up to form different types of protein including keratin, the most important protein involved in hair growth.

How does biotin increase hair growth and improve hair health?

Biotin plays an important part in nutrient breakdown and synthesis, i.e. in transforming carbohydrates and fats into energy. Sulphur, one of the active components of biotin is involved in the synthesis of collagen, responsible for healthy hair, skin and nails. Moreover, biotin speeds up metabolism and facilitates the proper nourishment of the hair follicle (more nutrients reach the hair follicle through the blood stream).
With that in mind I’ve compiled a useful list of supplements and foods that are high in biotin.

Biotin Dosage for Hair Growth

A normal daily diet should provide you with 30 micrograms of biotin. When now taking biotin specifically for hair growth, then doctors tend to recommend a dosage between 500 and 700 micrograms of biotin per day. Biotin is readily available as capsules or in liquid form. The best time frame to stick to in order to see results is at least 6 months.
Biotin deficiency cases are more common among pregnant women and are easily treatable with proper nutrition or biotin supplements, such as the above.
Biotin does not stimulate hair growth, rather it regenerates and renews hair follicles and hair roots that are already growing and helps to reduce the effects of alopecia. By doing this, hair becomes thicker, looks fuller and is much healthier. Biotin will cause noticeable improvements for those suffering from mild alopecia but is not likely to cause improvements for those who have been suffering from long term baldness.

Conclusion

Biotin-rich foods and supplements have been described as “miraculous” for hair growth, are all natural and therefore totally worth a try. While supplements work in different ways depending on each person, you will certainly notice improvements – don’t forget that a healthy diet and lifestyle are also essential!
