Biochanin A

Rob (PHH)

Name Ingredients:

Biochanin A (or BCA) is a chemical known as an isoflavone that is commonly found in red clover. Recently, BCA has been used in topical treatments claiming to treat hair loss.

Key insights:

  • The in vitro evidence suggests that biochanin A might inhibit 5α-reductase activity, which may be beneficial for those with hair loss due to androgenetic alopecia. 5α-reductase is responsible for catalyzing the conversion of testosterone to dihydrotestosterone (DHT) and increased activity (and subsequent increased DHT) is linked to the formation of androgenetic alopecia. 
  • The clinical evidence associated with BCA only uses it as an ingredient amongst many others, so it is not possible to know if any positive effects on hair growth arise from this ingredient or others.
  • Our experience tracking members: by itself, biochanin A alone is not enough to improve hair loss outcomes.
