Eucalyptus has a long history of traditional use in hair care, particularly in practices rooted in folk medicine and aromatherapy. Traditionally, eucalyptus oil is believed to stimulate the scalp, improve blood circulation, and thereby promote healthy hair growth. Its reputed antimicrobial properties also make it a popular ingredient in shampoos and hair tonics aimed at reducing dandruff and soothing itchy scalps. However, scientific evidence supporting these claims is limited. While some studies indicate that eucalyptus oil possesses antifungal and antibacterial properties, which could potentially help manage scalp conditions like dandruff, there is little direct clinical research linking eucalyptus oil to significant improvements in hair growth or overall hair health. Most of the available evidence is either anecdotal or based on the oil’s general antimicrobial and anti-inflammatory effects. Eucalyptus oil is commonly included in hair care formulations for its pleasant aroma and its potential to impart a cooling sensation to the scalp. Caution is advised, as the oil can be irritating to sensitive skin and should be used in diluted form. In summary, the use of eucalyptus for general hair care is primarily justified by tradition, with some supporting evidence relating to scalp health, but there is insufficient scientific validation for claims about hair growth or hair strengthening.
