Dermatar Extra Strength Therapeutic Shampoo contains coal tar and salicylic acid. Coal tar belongs to a class of drugs known as keratoplastics. It works by causing the skin to shed dead cells from its top layer and slow down the growth of skin cells. This effect decreases scaling and dryness. Coal tar can also decrease itchiness from these skin conditions. Salicylic acid is a hero in the world of dandruff care. Salicylic acid helps rid your scalp off dry skin and dandruff, which means reduced itchiness and irritation.

According to the UK National Health Service, coal tar is generally safe but if you used more than the recommended amount or used it more often than advised, you may get some symptoms. Make sure to read the label that comes with the product before you use it.
