Inquiries about utilizing apple cider vinegar for managing dandruff are common.
In the realm of home remedies, apple cider vinegar (ACV) has long been touted as a potential solution for dandruff. However, a closer examination of the scientific evidence reveals a more nuanced picture.
Recent research has shown that ACV, with its antifungal properties, may inhibit the growth of certain fungi, including Malassezia, a common culprit in dandruff [1][2]. Yet, it's essential to note that these findings are primarily based on lab studies, and there is a lack of high-quality research to support the effectiveness of ACV in treating dandruff in humans [1].
The traditional belief that ACV can help manage dandruff by reducing excess bacteria and yeast-like fungi on the scalp persists, but this remains unproven [2][4]. Some sources recommend diluting ACV and applying it topically to the scalp, but the potential benefits still lack robust clinical trials or scientific validation [1].
While the idea of ACV rebalancing the scalp's natural pH levels to help relieve dandruff symptoms is appealing, it's important to approach its use with caution. The ideal pH of the scalp is slightly acidic, around 5.5, and some commercial shampoos, even those marketed as anti-dandruff products, have alkaline pH levels [3].
The National Eczema Association warns that consuming large amounts of ACV may damage soft tissues in the mouth, throat, and stomach due to its high acidity [2]. Similarly, undiluted ACV, when left on the skin for too long, can cause irritation and chemical burns [1][3].
A small 2019 study investigating the effects of ACV on skin pH and skin water loss in people with atopic dermatitis found that ACV can decrease skin pH levels immediately after treatment, but the effects are only temporary [1].
To use ACV as a potential dandruff treatment, experts recommend starting with a low concentration, such as 1-2 tablespoons per 8 fluid ounces of water, once or twice a week, and gradually increasing the amount [4]. A patch test can be performed by applying a few drops of diluted or fully concentrated ACV to the back of the hand and monitoring for signs of irritation [4].
It's crucial to remember that while ACV shows promise as an antifungal agent in experimental settings and has a history of traditional use for dandruff, there is insufficient scientific or clinical evidence to confirm its effectiveness as a reliable dandruff treatment at this time [1][2][3][4]. Further well-designed clinical studies are needed to establish safety, efficacy, and proper application methods.
As always, anyone who experiences signs of scalp irritation or worsening dandruff should discontinue use and consult a dermatologist.

- In the health-and-wellness industry, apple cider vinegar (ACV) is often associated with predictive benefits for skin-care, namely as a potential solution for dandruff.
- Interestingly, the bipolar antifungal properties of ACV may inhibit the growth of Malassezia, a fungus linked to dandruff, according to recent science.
- Conversely, the scientific evidence available for the effectiveness of ACV in treating human dandruff is relatively scarce, with a lack of high-quality studies to substantiate the claims.
- Despite popular beliefs suggesting that ACV aids in balancing the scalp's natural pH levels to alleviate dandruff symptoms, this hypothesis remains unproven.
- It's imperative to approach the use of ACV for dandruff treatment with caution, as its high acidity can potentially damage soft tissues in the mouth, throat, and stomach if consumed in large amounts.
- Skin-care experts propose starting with a low concentration of ACV, such as 1-2 tablespoons per 8 fluid ounces of water, once or twice a week, and performing a patch test before application to gauge individual sensitivity.
