Achieving thicker and fuller hair is a common goal in today's beauty-conscious world. Many invest in hair products laden with chemicals, potentially harming your health. Fortunately, natural supplements can help you achieve the desired hair thickness and health. This guide combines insights from two articles to provide a comprehensive overview of the best hair growth supplements, focusing on biotin.

What is Biotin?

B7, also known as biotin, is a vitamin that supports various bodily functions. It helps convert carbohydrates into energy, supports healthy nerve function, and promotes average growth. Biotin is naturally present in foods like eggs, almonds, cauliflower, peanuts, and bananas. However, some individuals might need additional biotin supplements due to allergies, specific health conditions such as diabetes, or particular medication use.

Why Do Hair Growth Supplements Contain Biotin?

Hair growth supplements often contain biotin and vitamins like C, E, and folic acid. While biotin doesn't directly promote hair growth, it supports the process by increasing blood flow to the scalp. This enhanced blood flow is crucial for the growth of hair follicles. Thus, biotin supports overall hair health and can indirectly aid hair growth.

Benefits of Biotin for Hair Growth

Biotin supports hair growth by stimulating blood flow to the scalp (1). This is essential because each hair follicle requires adequate blood flow to grow. People with low blood flow to the scalp might notice slower hair growth. Therefore, biotin supplements can help improve this condition, promoting healthier hair growth.

Side Effects of Taking Biotin

Although biotin is generally safe, high doses may lead to adverse reactions like diarrhea, bloating, or ringing in the ears. It's crucial to consult a doctor before beginning a supplement program to determine the correct dosage (2). Typically, a daily dose of 100-300 micrograms is recommended. Additionally, ensure the biotin supplement is biologically active to benefit your body.

Other Essential Supplements for Thicker Hair

1. Eggs and Egg Whites:
   Eggs are a rich source of protein, healthy fats, and amino acids, all vital for hair growth. They also contain biotin, further supporting hair health (3).
2. Flaxseed Oil:
   Rich in omega-3 fatty acids and linolenic acid, flaxseed oil can substitute fish oil. It aids in hair growth and addresses scalp disorders like dandruff and psoriasis (4).
3. Green Tea:
   It's full of antioxidants and promotes hair growth. Drinking it hot can enhance its benefits, and adding honey or lemon can boost its health properties.
4. Hair Growth Shampoos:
   Products like Viviscal and Regrow Hair shampoos contain biotin, amino acids, and vitamins that strengthen hair strands and reduce shedding and breakage (5).
