Frequent Brushing for Shine: Contrary to the belief that frequent brushing will make your hair shinier, excessive brushing can actually damage your hair and lead to breakage.
Trimming for Faster Growth: Trimming your hair doesn't make it grow faster. Hair growth primarily occurs at the roots, so cutting the ends won't affect the rate of growth.
Cold Water for Shine: While rinsing with cold water may temporarily make your hair appear shinier, it doesn't provide any lasting benefits.
Shampooing Every Day: Daily shampooing can strip your hair of natural oils, making it dry and brittle. Most people can benefit from washing their hair every few days or as needed.
100 Brush Strokes Before Bed: The idea of brushing your hair 100 times before bed is outdated. Excessive brushing can lead to hair damage and breakage. Gentle brushing is sufficient.
Mayonnaise or Olive Oil as Conditioner: Using mayonnaise or olive oil as hair conditioner, once recommended, isn't as effective as commercial products and can be hard to wash out.
