The results of practicing yoga for healthy hair can vary depending on factors like your consistency, diet, and overall lifestyle. Typically, if practiced regularly, you may start noticing improved scalp circulation and reduced stress within 3-4 weeks, which are essential for healthy hair growth. Visible changes like stronger or shinier hair may take 2-3 months since hair grows slowly, at about half an inch per month. Pairing yoga with a nutrient-rich diet can further enhance the results. Remember, patience and consistency are key! :)
