Apple Cider Vinegar and Skin Health: What Science Says
Apple cider vinegar (ACV) has a long history as a household remedy, often touted for everything from scalp care to foot soaks. But while many people swear by it, research on its effects for skin and scalp health is still limited. Let’s separate anecdote from evidence and see what’s actually known.
ACV and Dandruff: The Evidence (or Lack Thereof)
There’s currently no scientific proof that ACV cures dandruff. Still, countless personal accounts online report benefits such as:
- Helping balance scalp pH
- Supporting natural shedding of dead skin cells
- Potentially reducing fungal growth on the scalp
These effects are purely anecdotal—more research is needed to confirm whether ACV truly helps with dandruff or other scalp issues.
What Research Suggests
- A 2022 review suggested ACV might help with dry scalp, which is sometimes mistaken for dandruff but has different causes.
- ACV shows antimicrobial and antifungal properties, which could be useful since bacteria and fungi can contribute to scalp problems.
- One study found undiluted ACV has strong antimicrobial effects, but at 25% dilution, it was less effective against Candida yeast compared to bacteria.
Takeaway: ACV may offer some disinfecting benefits, but its effectiveness depends on concentration and the type of microorganism. More studies are needed.
Anecdotal Methods for Scalp Use
Although not scientifically proven, common approaches include:
- Dilution: Mix 2 parts ACV with 1 part water.
- Application: Spread evenly across the scalp.
- Wait time: Leave on for around 15 minutes.
- Rinse: Wash thoroughly with warm water.
- Frequency: Often used twice a week.
Safety tip: Avoid contact with eyes and stop use if you notice stinging, itching, or changes in skin color.
Precautions
- Always consult a doctor before applying ACV to skin, especially if you have sensitivities or existing conditions.
- Stop immediately if irritation occurs.
- ACV is not a replacement for medical treatment.
The Bottom Line
Apple cider vinegar may have mild antimicrobial effects and provide anecdotal relief for some people, but scientific evidence is limited. Its role in skin and scalp health remains uncertain.
Best approach: Use ACV cautiously, stay informed, and rely on professional guidance for persistent skin or scalp concerns.
