DO YOU KNOW FREQUENT USE OF CHEMICAL SHAMPOO AND HAIRCARE CAUSES HAIR DANDRUFF?? Shampooing is another frequent cause of dandruff. Why do we forget that cleaning the scalp is equally important as cleaning the body? You should cleanse your hair with good shampoo and natural haircare products at least twice a week or thrice as needed. Remember a lot of shampooing is also not good, take appropriate amount depending upon the length and wash. Always go for chemical-free or herbal shampoos and haircare products for massive results.
