Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Birch (Betula species) has a history of traditional use in hair care, particularly in European and Russian folk medicine. Birch leaf extracts and birch tar have been used as ingredients in hair rinses, shampoos, and scalp treatments. Traditional claims include promoting hair growth, improving scalp health, and reducing dandruff. These uses are largely based on the astringent, mildly antiseptic, and anti-inflammatory properties attributed to birch leaves and bark. Folk remedies often suggest rinsing the hair with birch leaf infusions to strengthen hair and add shine.

However, there is a lack of robust scientific studies directly validating birch’s efficacy for general hair care or for specific concerns such as hair loss or dandruff. The available evidence is mostly anecdotal or based on the known properties of birch constituents, such as flavonoids and saponins, which may support scalp health in a general sense. Some commercial hair care products include birch extract, leveraging its traditional reputation, but clinical trials are lacking. Overall, while birch’s use in hair care is well-rooted in tradition, scientific support is minimal, and evidence is considered weak to moderate (2/5).
