GlossaryAbsorption

process of substances entering cells or tissues

Absorption refers to the process by which substances, such as nutrients, chemicals, or medications, are taken up by cells or tissues. In the context of hair and skin, it often involves the uptake of topical treatments or nutrients through the skin or hair follicles, which can influence hair health and growth. For example, minoxidil, a common treatment for hair loss, is absorbed through the scalp to stimulate hair follicles.
