Waxy buildup on your scalp can be caused by a number of factors, from infrequent washing to seborrheic dermatits, a type of eczema that often flares up in cold weather. Fortunately, there are many potential remedies, from shampoos to prescription drugs. Home remedies may work to eliminate waxy buildup and there's no harm in trying them before you seek medical help.
Wash your hair with lemon shampoo or add a spoonful of lemon juice to two spoonfuls of clarifying shampoo. Scrub your scalp with your fingertips and allow the shampoo to remain on your scalp for several minutes before rinsing. Repeat daily until the waxy buildup is gone.
Rinse your hair with vinegar water. Mix 1/2 cup white or apple cider vinegar with 2 cups of warm water. Pour the mixture through your hair after rinsing out your shampoo. Do not rinse out the vinegar water; the vinegar scent will dissipate as your hair dries.
Use zinc-based anti-dandruff shampoo if your waxy scalp is accompanied by dandruff. A number of over-the-counter and prescription formulations are available.
Wipe your scalp with astringent between washes. Apply salicylic acid acne toner or plain witch hazel with a cotton ball.
Visit a dermatologist if the waxy buildup on your scalp continues. Your doctor can prescribe medication or a prescription shampoo to help treat the problem.
