According to Lifehacker the longtime touted advantages of using apple cider vinegar, as a cure all, are a myth. When it comes to revitalizing skin and hair, cosmetic chemist Randy Schueller says, don’t hold your breath. He explains “other than helping to remove mineral buildup, vinegar doesn’t really provide any benefit.” Looking for shinier hair? Nope, Schueller says it’s just folklore. If you’re hoping that sipping a teaspoon will help with miraculous weight loss, Lifehacker says —think again. One study found that apple cider vinegar may helped people lose a “mere two to three pounds over 12 weeks.”
