Hair is fickle. It can be beautiful at one time and messy the other. When you move your fingers through your hair, you want it to be a soft and soothing. But, when you have dandruff or dry hair, it can be very irritating.
You may then take a shower with some shampoo and your hair might be back to normal, soft and gorgeous as before. In any case, that is just temporary. Doing it the right way matters and it keeps your hair healthy and the beautiful look long lasting.
Mistake#1 You wait as long as you can between washes
You should wash your hair whenever it feels like washing. You can do it once in a week during winters and every day during summers. It is up to you.
