Hi Doctor...I Have Been Using Mintop Foam5 More Than 3

Hi doctor...I have been using mintop foam5 more than 3 years... First i use mintop 5 forte because of itching and dandruf i stop using forte and now using foam 5. My doubt is i am staying in UAE. Usually i kept my can in my bedroof In summer season when i take foam for applying hair at the same time it becomes water. So i just put can top of scalp and press the can and foam comes to scalp. Do i can continue this procedure??
