    Glossary Concentration

    amount of substance in a given volume

    Concentration refers to the amount of a substance present in a given volume of solution or mixture. In the context of hair and biology, it could relate to the concentration of nutrients, chemicals, or medications applied to the scalp or hair follicles, which can influence hair growth and health. For example, a higher concentration of minoxidil in a topical solution might be more effective in treating alopecia, but it could also increase the risk of side effects.
