Does drinking coffee help to maintain healthy hair growth?
Since you ingest coffee orally, it will first pass through the gastrointestinal organs to be absorbed by the organism at a later time. Subsequently, it is distributed throughout the body and only a tiny quantity reaches the scalp and the hair roots directly. As a result, a local and direct supply of caffeine is meaningful and necessary. Even the consumption of 50 cups of coffee would not provide the hair roots with enough caffeine.
