Biotin is generally considered safe for most people when taken in appropriate doses.

It is a water-soluble vitamin, which means that excess biotin is usually excreted through urine.

However, there are a few medications and substances that may interact with biotin.

These include:

Anti-seizure medications:

Certain anti-seizure medications, such as carbamazepine (Tegretol), phenobarbital, and phenytoin (Dilantin), may decrease biotin levels in the body.

Antibiotics:

Long-term use of certain antibiotics, such as sulfa antibiotics, may impair the absorption of biotin.

Anticonvulsant medications:

Valproic acid (Depakene, Depakote), used for seizure disorders and bipolar disorder, may lower biotin levels in the body.

Raw egg whites:

Consuming raw egg whites regularly may interfere with biotin absorption. Raw egg whites contain a protein called avidin, which binds to biotin and prevents its absorption. Cooking egg whites denatures avidin and eliminates this issue.

Question and answer

Does brand matter with biotin?

When it comes to biotin shampoos or any hair care products, the brand can play a role in terms of the quality and formulation of the product. Different brands may use different concentrations of biotin and other ingredients, and the overall effectiveness of the product can vary.

Choosing a reputable and trusted brand can often provide some assurance of the product’s quality. Established brands often invest in research and development, adhere to regulatory guidelines, and undergo testing to ensure the safety and efficacy of their products.

However, it’s important to note that the effectiveness of biotin shampoos may vary from person to person. Biotin can have varying effects on individuals, and the results may depend on factors such as the underlying cause of hair issues, overall hair health, and individual response to the product.

Is too much biotin shampoo bad for your hair?

Biotin is a B vitamin that is often included in hair care products, including shampoos, due to its potential benefits for hair health. Biotin is believed to contribute to the strength and thickness of hair strands, as well as promote overall hair growth.

While biotin can be beneficial for hair when used in appropriate amounts, it’s important to note that using too much biotin shampoo or any other hair care product can have potential drawbacks. Excessive use of biotin shampoo may lead to an imbalance in your scalp’s natural oil production, causing your hair to become greasy or oily.

Additionally, using excessive amounts of any shampoo can strip the hair and scalp of their natural oils, leading to dryness, irritation, and potential damage.
