HI there,thanxs for putting up the question on healthcaremagic. Firstly don t panic! Hair fall can be due to various reason, -wrong eating habits,constipation,malnutrition,hypothyroidism,dandruff etc.so rule out the above causes first. try to have a healthy lifestyle,eat balanced diet,drink plenty of water. To prevent the dryness of hair: Heat and sun exposure are common causes of dry hair. If you live in a dry, humidity-free climate, always protect your hair before going outdoors. avoid long-term exposure to dry or windy air. protect your hair by wearing a cap when swimming in the pool, since salt water and chlorine can easily damage your hair. •avoid daily shampooing •use a protein-enriched conditioner to repair hair damage •blow-dry your hair less frequently •avoid heated styling products, such as flat irons, curling irons, and electric rollers •condition your hair every time you wash it •use a shampoo and conditioner that are meant for your hair type; there are hair products specifically formulated for chemically treated hair Try washing your hair once or twice a week to retain more moisture. You can also apply hair oils or leave-in conditioners to add luster and softness. If a medical problem is causing your dry hair, your hair may improve once you treat the underlying condition. please visit a dermatologist,if the condition still persists. hope it helped.
