Chemicals and hair dryness
Medical studies indicate that maintaining healthy and thick hair requires a comprehensive approach that includes proper nutrition, hormonal balance, and external care. A deficiency in essential nutrients such as iron, ferritin, vitamin D, zinc, biotin, and omega-3 fatty acids leads to reduced blood and oxygen flow to the hair follicles, causing hair loss and weakening of density and dryness. Additionally, strict diets and a lack of proteins—necessary for keratin production—accelerate hair damage and breakage. External factors like excessive heat, chemical hair products, and sleeping with wet hair damage the hair cuticle and cause dryness at the ends, while fungi and bacteria proliferate, leading to dandruff. Psychological stress and sleep disturbances increase cortisol levels, which weaken the hair growth cycle and hasten hair fall. Therefore, it is recommended to adopt a diet rich in eggs, fish, and vegetables, to gently dry the hair, and to use sulfate-free products to maintain healthy hair and promote its sustainable restoration.
