Itching, redness or rashes on your scalp can indicate an internal or external problem. But, constant itching will always make the problem worse, which is why it's important to discover the cause of the problem and take the appropriate steps. You may also notice that your problems get worse as the weather gets cooler or warmer, so take everything in to account before you self-diagnose. If you notice serious signs like bleeding or a milky discharge, it's best to consult a professional.
Use all-natural remedies. Lemon oil is good for a dry scalp. Tea tree oil, from Australia is good for controlling sebaceous glands, dry scalp and head lice.

Essential oils should be mixed with carrier oils like jojoba or olive oil
Purchase an over-the-counter treatment. Psoriasis, which shows up as patchy red skin covered with silver scales -- or dermatitis, which is marked by greasy skin with white scales, can be relieved with over-the-counter medications. Choose one with tar, salicylic acid or ketoconazole to soothe irritation. Products like Scalpicin and Neutrogena Shampoo with tar, can help ease irritation, but psoriasis is an immune system problem and may require oral medications like cyclosporine or methotrexate.
Use apple cider vinegar. You hair products may be contributing to your scalp problem, so take a break from your regular routine and try an apple cider vinegar solution. Mix one part apple cider vinegar and one part water in a clean spray bottle. Wash your hair with a high quality moisturising shampoo, rinse and spray the vinegar solution over your scalp until it is well coated. Gently rub it in for five minutes and let it sit for a few minutes. Rinse well with warm water.
