I had no idea about this…

A review from 2022 suggested that ACV “could potentially help with dry scalp.” Dry scalp can be mistaken for dandruff since they often look alike, but they have different causes. As of now, “It’s uncertain whether ACV would help with dry scalp, dandruff, or both, since they stem from different issues.” That’s why continued research is so important.

Overall, ACV may have qualities that could support skin health. For example, it “may offer some disinfecting and antifungal effects.” This is notable because certain bacteria, such as staphylococcus, may play a role in dandruff. In addition, conditions that resemble dandruff are sometimes actually fungal infections.

One study “found that although undiluted ACV has strong antimicrobial abilities, not every microorganism responds to it.” In other words, ACV can kill some germs but not all. The same study reported that “at a 25% dilution, ACV was less effective against Candida yeast compared to bacteria.” This shows that both the strength of the ACV and the specific microorganism make a difference.

Because of this, “the pros and cons of using ACV for any skin concern still need further investigation.” More scientific work is necessary to fully understand its effects.

How People Use ACV for Scalp Problems (Based on Personal Reports)

Even though there isn’t strong scientific evidence for ACV as a dandruff remedy, the 2022 review did mention common methods used for dry scalp. If you’re thinking about trying ACV for your scalp, here’s a general summary of these popular approaches:

• Dilute properly: For dilution, “combine two parts ACV with one part water.” This reduces the vinegar’s acidity so it’s less harsh on the skin.
• Application: Spread the diluted mixture across your scalp.
• Wait time: After applying, “leave it on for fifteen minutes.”
• Rinsing: When the time is up, “pour the ACV-water mixture through your hair,” then “rinse well with warm water.”
• Frequency and safety: People often repeat this twice weekly. A key safety reminder: “Avoid getting the mixture in your eyes,” as it can sting.
