Ajuga (commonly known as bugleweed) has a history of traditional use in some cultures for various skin and scalp conditions, including dandruff. Folk remedies often involve the topical application of Ajuga extracts or infusions, sometimes in combination with other herbs, to soothe the scalp and reduce flaking. The rationale behind such use is typically based on Ajuga's reputed anti-inflammatory and antimicrobial properties, which are believed to help alleviate symptoms associated with dandruff, such as irritation and the presence of Malassezia yeast implicated in seborrheic dermatitis.

However, scientific validation for Ajuga's efficacy specifically in treating or supporting dandruff is minimal. There are no well-controlled clinical trials or robust pharmacological studies directly investigating its effects on dandruff or the underlying causes. Most available evidence is anecdotal or derived from general knowledge about the plant's constituents, which include phenolic compounds and flavonoids with potential antimicrobial activity. As such, while Ajuga's use for dandruff is supported by tradition in some herbal medicine systems, the overall quality and quantity of evidence are low, and this application should be regarded as primarily historical rather than evidence-based.
