An itchy scalp is a common symptom of dandruff. Dandruff can be caused by dry skin or a common skin condition called seborrheic dermatitis, the Mayo Clinic reports. Head lice may also cause your scalp to become very itchy. A variety of shampoos and topical solutions may offer relief from scalp itch.
Considerations
Seborrheic dermatitis most often occurs on the scalp, ears, eyebrows, eyelids and chest, notes the American Academy of Dermatology, or AAD. Unlike dandruff, which generally causes itching and flaking, seborrheic dermatitis may also cause redness.
Head lice usually affect school-age children, according to the AAD. Girls are more vulnerable to head ice infestation because they typically have longer hair than boys. Common symptoms of head lice include a very itchy scalp, red bumps and tiny tears in the skin.
Prevention/Solution
Seborrheic dermatitis is not preventable but it can be controlled. It's difficult to guard against the spread of head lice in children because they are in such close proximity throughout the school day. Ask your child not share personal care items such as brushes, combs and hats with other children. Regularly shampooing your hair may help keep dandruff at bay, according to the Mayo Clinic.
Effects
A variety of over-the-counter shampoos are available to treat stubborn cases of dandruff and help relieve a very itchy scalp. Tar-based shampoos can help diminish symptoms of dandruff and seborrheic dermatitis by slowing the speed in which skin cells on your scalp die and flake off. Zinc pyrithione shampoos can decrease the fungus on your scalp that can lead to dandruff and seborrheic dermatitis.
Contact your health care provider if over-the-counter remedies fail to improve itchiness and other symptoms of dandruff or seborrheic dermatitis. You may need a stronger, prescription shampoo.
Types
Pyrethrin and permethrin are the first line of treatment for head lice, according to the Mayo Clinic. You can also physically remove head lice with a fine-toothed comb while your hair is wet. Repeat the process approximately every other day for two weeks. Prescription-strength medications are also available to combat head lice.
Warning
Seborrheic dermatitis is a lifelong condition that results in flare-ups from to time, Medline Plus reports. Contact your doctor if your scalp becomes painful, or drains pus or fluid.
Head lice can cause you to scratch your scalp with such force that you tear your skin, the Mayo Clinic notes. Notify your health care provider if broken skin becomes infected.
