I am 17 years old.In summers how many times I can wash our hair's in a week because I have long hair's so it was not possible to wash daily with shampoo and I also go outside in sun to play in stadium. My hair get damaged and also I want to know oil is necessary for hair in summer's when should I apply it and I use patanjali aloevera shampoo, damage control conditioner and Jiva bhringraj oil is it right.
