Opinions on how often to shampoo hair in summer vary widely, with some suggesting daily washing while others warn against it due to potential hair loss. Dr. Rinky Kapoor, Co-Founder and Director of The Esthetic Clinics, emphasizes that the ideal shampoo frequency depends on individual scalp type and environmental factors. In hot and humid conditions, increased sebum production and sweat can lead to scalp congestion and irritation. For individuals with oily scalps or those who exercise, washing every alternate day is recommended for hygiene. Conversely, those with dry or sensitive scalps should limit washing to two to three times a week to avoid stripping the scalp of its natural oils. Using a mild, sulphate-free shampoo is crucial to maintain the scalp's lipid barrier. Additionally, rinsing the scalp with plain water after sweating can help reduce microbial buildup, while proper drying after washes is essential to prevent fungal overgrowth during humid weather.
