Social media is full of conflicting hair growth advice, but experts say most of it is based on 'vibes' not science. This article cuts through the noise, explaining the actual process of hair growth, what truly determines length, and effective, science-backed strategies for achieving healthier hair.
The article highlights the unreliability of hair care advice from social media influencers, noting that many promised hair growth products lack scientific backing. It explains the hair growth cycle, consisting of the anagen (active growth), catagen (transition), telogen (resting), and exogen (shedding) phases. Hair length is primarily determined by the duration of the anagen phase (influenced by genetics, hormones, nutrition, and environment) and preventing breakage. Common causes of damage include excessively drying treatments (heat, chemicals like bleach), and tight hairstyles leading to traction alopecia. Hair type also affects care, with curly hair benefiting from deep conditioning and protective styles, while straight hair needs lighter products. Effective strategies for hair growth include maintaining a healthy scalp by washing regularly to prevent dandruff and using conditioners/oils, employing proven products like minoxidil (Rogaine/Regaine) and prescription options like spironolactone or finasteride (under dermatologist guidance), managing stress, and eating a balanced diet rich in iron, zinc, and vitamin D, while avoiding unnecessary supplements. For severe hair loss, identifying the underlying cause (e.g., autoimmune conditions, hormonal imbalances, stress-induced telogen effluvium) is crucial for effective treatment, and consulting a board-certified dermatologist is recommended.
