A healthy and clean scalp naturally secretes oils for lubrication, so there is no need to grease or apply oil every day. Sometimes different factors, such as extreme weather conditions, can cause the scalp to feel dry, so you may need to use a product. Oil is great for relieving dry and itchy scalp--just apply a few drops to your fingertips and gently massage onto the affected area. The days of applying pomade directly to your freshly washed scalp as a routine are long and gone--only oil or grease your scalp as needed.
