"The high acidity (organic malic acid) plus powerful enzymes (life chemicals) in ACV kill the bottle bacillus, a germ responsible for many scalp and hair conditions. The problems caused by bottle bacillus include itching scalp, dandruff, thinning hair and often baldness. Every hair has its own oil can. Bottle bacilli clogs the openings. Scales and small dry crusts are formed. Itching and dandruff result. The oil-starved hairs either fall out or break off, causing thinning of the hair and often baldness. Apple cider vinegar not only kills bottle bacillus, but stimulates the oil cans to healthier, balanced activity. Pour two tablespoons ACV in cup. Moisten cotton with water, then soak in the ACV. Part the hair in sections, and apply directly to scalp. Leave on for at least 15 minutes, up to two or three hours, before shampooing… this helps to restore the proper acid/alkaline balance to scalp. For acute cases, this should be done daily or before every shampoo. For a healthy, after shampoo rinse (also for body) add 1/3 cup apple cider vinegar to quart of rinse water." - Paul C. Bragg
