Overview

• August 28 reports from ámbito.com and TN.com.ar detail mixing one part apple cider vinegar with two or three parts water, applying to clean damp hair, and rinsing after three to five minutes.
• Milenio offers similar guidance with a 1:2 dilution, a 10–15 minute contact time, and suggests weekly use for cosmetic results.
• Outlets advise repeating the rinse once or twice per week based on scalp tolerance and the effect sought.
• Cited benefits include pH balancing, residue removal, smoother cuticles, and added shine that can make gray hair look less dull or yellow.
• Coverage notes that gray hair results from reduced melanin production by melanocytes and urges patch testing and stopping use if irritation occurs, with no clinical evidence that vinegar reverses graying.
