What Causes An Itchy Scalp?

Allergic Reaction To Hair Products

The skin on the scalp is very sensitive, so developing an allergic reaction to hair products is extremely common. The three most common hair products that cause harmful reactions are shampoo, conditioner, and hair dye. It is fairly easy for individuals to know if they are having a bad reaction to one of these products. Individuals will get a bad rash on the scalp almost instantly after using the hair product. The rash will also likely develop on any area of the body that came in contact with the product while it was being used. This rash will cause an intensely itchy scalp. It is very important for individuals to immediately stop using the shampoo, conditioner, or hair dye they think caused the allergic reaction.

Head Lice

Head lice are parasitic insects that like to live on the human head. They use the hair as protection while they feed on blood from the scalp. Red bumps will develop on the scalp once the head lice start feeding. These bumps will be extremely itchy over time. The movement of the insects may also cause individuals to feel a slightly itchy sensation on the scalp. The only way to get head lice is to come in close contact with an infected individual. If individuals believe they have head lice, then it is important to take immediate action before the bugs spread throughout the home. Washing the hair with a special shampoo designed to kill the insects is the best form of treatment. It is also recommended to wash all bedding in hot water.
