Surely you have a bunch of shampoo bottles and about a dozen hair masks and conditioners. The questions is-do you own a scrub for the head scalp?
It is highly important to scrub the skin of the scalp at least once a month with a special scrub or even natural sugar added into shampoos. Why? Because in the winter season especially; we tend to wear hats, and change the temperature from hot to cold conditions which isn't good for the skin.
You can find a choice of hair scrubs and/or shampoos with scrub particles, in the local pharmacies or cosmetic sections of the mall. Apply a little bit onto the scalp and massage carefully, avoiding to irritate the skin, and see the magic happen.
