Can you put biotin in your shampoo?

While biotin has been shown to be effective in promoting healthy hair growth, applying it directly to the scalp in the form of shampoo is unlikely to be effective. Biotin is a water-soluble vitamin, meaning that it is easily washed away and absorbed by the skin, rather than penetrating the hair shaft.

For biotin to have an impact on hair health, it is generally recommended that it is taken orally as a dietary supplement. Biotin is found in many foods, including:

- Liver

- Kidney

- Eggs

- Dairy products

- Nuts

- Seeds

- Whole grains

If you are considering taking a biotin supplement, it is important to speak with a doctor first to determine the appropriate dosage and to ensure that it is safe for you.
