Itchy skin is known as pruritis. Your scalp, however, can itch for a variety of reasons -- from dandruff to head lice. Itching from head lice requires a special type of medicated lotion. If you suffer from conditions such as psoriasis, you're also more likely to experience an itchy scalp. Whatever your condition, while anti-itching lotions can relieve some of the discomfort, they may not address the underlying issues. Speak to your doctor if you have persistent itching.
Tar-based Lotions
Tar-based lotions and shampoos can slow down the speed at which skin cells on the scalp multiply. This can help relieve your itchy scalp. Most tar-based lotions have a strong smell, which some consider unpleasant. MayoClinic.com lists T-Gel, Tegrin, Sebutone, Z-Tar and Ionil T as tar-based shampoo lotions that can help reduce itching.
Vitamin D Lotions
Vitamin D scalp topical treatments can combat itchiness, according to MayoClinic.com. Calcipotriene is a form of vitamin D lotion also available as a foam. According to the University of Maryland Medical Center, calcipotriene can block the reproduction of scalp skin cells. It can also work as an anti-inflammatory, helping to reduce itchiness.
Corticosteroid Creams and Lotions
Corticosteroid creams are mainly used to treat psoriasis symptoms. However, they do reduce itching and inflammation in the scalp. Lotions range from class I to VIII, with I being the most potent, according to the University of Michigan Health System. Stronger corticosteroid lotions are usually prescribed by a doctor. In some cases, side effects include irritation and skin marks. You should speak to your doctor before applying this type of lotion.
Head Lice Lotion
Use this lotion only if you notice definite signs of head lice. Itching is one symptom, but you should also see small lice and little white eggs drop from your hair when your rub your head over a piece of dark paper. Several over-the-counter lotions are available. Stronger products with 1 per cent lindane may require a prescription. Be sure to follow the instructions, because if used incorrectly these products can affect the nervous system, according to the University of Florida IFAS Extension. Avoid using any head lice treatments until you're certain that lice are causing the itching.
