apple cider vinegar for hair side effects - #21042
I am really curious about apple cider vinegar for hair side effects since I just started using it. A friend raved about all the benefits, like how it makes hair shinier and helps with dandruff. So I thought, why not give it a shot, right? I mix a bit of apple cider vinegar with water and use it as a rinse after shampooing. At first, I was all in, but now I’m starting to wonder if I should be cautious. My scalp has been itching a bit more than usual, and I can’t help but think it’s related to the vinegar. I read some horror stories about apple cider vinegar for hair side effects online, like it causing severe dryness or even chemical burns if used incorrectly. Is that really a thing? Should I be worried? My hair did feel softer initially, but now, I’m not sure. I’ve also noticed some flakiness, which I’ve never had before. Has anyone else experienced this? I don’t want to ruin my hair, but the shine was nice, ya know? I keep debating if I should stop using it or maybe dilute it more, or what if I'm just overreacting? Like, is it just me or are there real apple cider vinegar for hair side effects that I should be aware of? Would appreciate any insights!

Doctors' responses
Apple cider vinegar (ACV) is popular for hair care due to its potential to enhance shine, encourage a healthy scalp, and even help with dandruff. That being said, you’re not alone in experiencing some possible side effects. The itchy scalp and flakiness you’re describing might indeed be linked to ACV use. ACV is acidic (pH around 2-3), and while human scalp is naturally acidic too, its normal pH is around 4.5-5.5. Using an acidic rinse like ACV, especially without proper dilution, can lower the scalp’s pH too much. This can lead to scalp irritation, itchiness, and increased dryness. Some people also experience a mild burning sensation or redness. In more extreme cases, if applied undiluted or left on too long, ACV can cause burns or, ironically, exacerbate dandruff if the scalp becomes overly dry and irritated. These symptoms should be taken seriously, especially if they worsen or cause discomfort.
To help alleviate these issues, you might want to consider diluting the vinegar more. A common ratio is three parts water to one part ACV, but you can dilute further if you’re sensitive. Also, reduce frequency of application; it doesn’t need to be used every time you wash your hair—trying once a week could be a good start. If the symptoms persist, it may be worth discontinuing its use altogether. Remember too that individual reactions can vary, so while some find ACV beneficial, others might not have the same experience. If your symptoms worsen or if there’s no improvement after adjusting how you use it, it’s a good idea to consult with a healthcare professional or a dermatologist. They can help determine if ACV is the right product for you or if another condition might be affecting your scalp health.
