Rating (out of 5): 2

Aloe vera is used to support or treat dandruff primarily based on preliminary scientific evidence, along with a history of traditional use. Dandruff is commonly associated with scalp irritation, dryness, and the overgrowth of Malassezia yeast. Aloe vera gel contains polysaccharides, glycoproteins, and other bioactive compounds that have demonstrated anti-inflammatory, antimicrobial, and moisturizing effects in laboratory studies and limited clinical trials. A small randomized controlled trial published in 1999 (Vardy et al., 1999) found that topical application of aloe vera extract significantly reduced symptoms of seborrheic dermatitis (a condition closely related to dandruff) compared to placebo. The study reported improvements in scaling and itching, suggesting that aloe vera may help alleviate dandruff symptoms through its soothing and antifungal properties. Additionally, aloe vera’s hydration and wound-healing effects may help restore the scalp barrier and reduce flakiness. However, the number of high-quality clinical studies is small, and most evidence comes from in vitro or animal models or small human trials, so the overall strength of evidence is moderate to low. In summary, while aloe vera’s use for dandruff is partly rooted in traditional practices, there is enough preliminary scientific evidence to justify its inclusion in some dandruff treatments, though more rigorous clinical trials are needed to confirm its efficacy and optimal use.
