Contact Dermatitis
You should improve how well you rinse the shampoo out of your hair if you have an itchy, dry, or flaky scalp. Shampoo residue might irritate your scalp. In addition, you may have allergic contact dermatitis if you have a rash and an itchy scalp. The causes and degree of sensitivity for contact dermatitis symptoms vary. Those who color their hair frequently have this condition. Para-phenylenediamine or PPD, a dye component in black hair colors, is often the culprit.
You can also be allergic to any shampoo, conditioner, or hair products that come in contact with your scalp. Skin redness, hives, leaking blisters, and scaly or flaky skin are signs of allergic contact dermatitis. You must avoid using the irritating substance to relieve the itching. Once the material has been removed from the skin, most contact dermatitis cases heal on their own. However, if rashes cover a vast region of the body, are close to the eyes or mouth, or don’t get better with home remedies, you should consult a doctor.
