Avocados. Avocados are best known as a good source of folate and unsaturated fats, but they're also rich in biotin ( 17 ). A medium avocado (200 grams) contains at least 1.85 mcg of biotin, or 6% of the DV ( 8 ).
Foods that contain the most biotin include organ meats, eggs, fish, meat, seeds, nuts, and certain vegetables (such as sweet potatoes) [2,12].
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.
Sweet potatoes
They are also one of the best vegetable sources of biotin. There are 2.4 mcg (8% of the recommended daily value) of biotin per 1/2 cup of cooked sweet potato. Along with the vitamin A in sweet potatoes, which is also good for the eyes and skin, the biotin makes sweet potatoes a superfood for skin health.
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.
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.
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.
While biotin is added to some shampoos that claim to reduce hair loss, there is no evidence that this works. Consuming foods rich in healthy vitamins and minerals will help with overall hair health.
One of the most versatile and common foods, tomatoes are also a rich source of biotin. Including only one big tomato in your daily diet can supply your body with plenty of nutrients. This will ensure your body stays healthy and gets its required dose of biotin on a regular basis.
Excessive ingestion of raw eggs may also cause biotin deficiency because the protein avidin in egg white binds biotin, decreasing its absorption.
Biotin is found naturally in foods such as meat, fish, eggs, seeds, nuts and certain vegetables, such as sweet potatoes, spinach, and broccoli.
So which supports hair growth more: collagen or biotin? Based on scientific studies, it seems that collagen has a better claim to improving the condition of your hair. However, both can actually be used together for well-rounded nutrition and countless health benefits, aside from promoting hair regrowth.
These include hair loss (alopecia) and periorificial dermatitis; scaly, red rash around the orifices, i.e., eyes, nose, and mouth (also called “biotin-deficient face”). The rash is similar to that of zinc deficiency. Patients may also develop conjunctivitis and skin infections.
If no home remedies work for your hair loss, use a daily biotin supplement for at least 6 months to start seeing results.
Answer: No Vitamins are better or worse for hair growth.
There are no vitamins that target hair growth.
Biotin also promotes hair growth and regrowth in those who are experiencing hair thinning, hair loss, or are having it hard to grow out their hair. This process can take time with consuming the supplement daily for a period of 4-6 weeks minimum to a few months for optimal hair growth.
Eggs are full of B vitamins, protein, iron, and phosphorus. The yolk is an especially rich source of biotin ( 5 ). A whole, cooked egg (50 grams) provides approximately 10 mcg of biotin, or approximately 33% of the DV ( 4 ).
Here's the truth: You can't change the size of your hair follicles. If you were born with fine hair, it's genetics, and no product will completely alter that. Of course, there are ways to maintain your hair health, add volume, and keep it from getting any thinner.
"There are specific juices that can be beneficial for the health of your hair and scalp, including aloe vera juice, kiwi juice and cucumber juice." According to Synder, spinach is highly concentrated with vitamin B, which restores shine and promotes hair growth.
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.
