The bottom line
Some of the best sources of biotin include legumes, egg yolks, organ meats, nuts, seeds, mushrooms, avocados, sweet potatoes, and yeast. Biotin supplements are available as well, but most people can get all of the biotin they need by eating a balanced diet.
Consuming foods rich in healthy vitamins and minerals will help with overall hair health. The best natural sources of biotin are meat, eggs, fish, seeds, nuts, and vegetables. These will help fortify your hair follicle by boosting your keratin, according to the National Institutes of Health.
Vitamin B7 is found in a number of foods, though in small amounts. This includes walnuts, peanuts, cereals, milk, and egg yolks. Other foods that contain this vitamin are whole meal bread, salmon, pork, sardines, mushroom and cauliflower. Fruits that contain biotin include avocados, bananas and raspberries.

In short, no. While biotin has proven benefits for hair growth in people with biotin deficiencies, it doesn't have any effect on male pattern baldness. MPB is hormonal and genetic, and biotin, as a vitamin, simply isn't involved in the male balding process.
There's no strong evidence to support using biotin for hair growth or to prevent hair loss in people without a deficiency. Because hair thinning and poor hair growth are sometimes associated with a biotin deficiency, correcting a deficiency can help restore hair growth in some people.
People at risk for biotin deficiency include people with BTD, chronic alcohol use, malnutrition, and IBD. Those who are pregnant and lactating as well as those who take certain medications are also at an increased risk.
The amount of biotin suggested for hair growth usually ranges between 100 - 1,000 micrograms (mcg) daily, but this number varies based on your body's reaction to biotin.

The short answer is yes, biotin can definitely help African American hair growth. This nutrient is essential for keratin production, which is the protein that makes up our hair, skin, and nails. Biotin deficiency can lead to dry, brittle hair that breaks easily something that nobody wants!
Carrots. Yes, they're a stellar source of biotin, but carrots have loads of other skin and hair benefits. “Beta-carotene [in carrots] works to counteract everything from dry skin, to dandruff, to wrinkle formation,” says Glassman.
Raspberries, blueberries, and blackberries, are all high in biotin. Not to mention, they're usually loaded with antioxidants for healthy, glowing skin. So if you have a sweet tooth, have a hand full of berries instead of a candy bar.
