There are external factors that influence the dryness and itching of the scalp, such as:

  • Skin processes such as atopic dermatitis or psoriasis.
  • Age has a direct influence on the health of the hair, reaching an advanced age will cause the hair to start to feel drier and it does not only happen with the hair, it can also be noticed in the skin.
  • Living under a lot of emotional or physical stress are factors that can cause hair damage, such as dryness, itching, or even hair loss.
  • Genetics can play a role if you have a history of family members suffering from dryness or other hair conditions.

Another type of factor that can affect the health of your hair is hormonal changes. These can be:

  • Changes in temperature or seasonal changes.
  • The lifestyle of a person who does not maintain a good diet or cigarette smoking.
  • Medications can also influence these conditions.
  • Another factor that can be overlooked is the degree of pollution suffered today in which the hair is often very affected.
  • The shampoo can be harmful to the hair if the right one is not used, which is why there are so many types, as well as soaps and hair treatments.
  • When the scalp completely loses its natural moisture, this results in the deterioration of its protective layer. This allows toxic substances to easily enter the scalp, damaging your skin and causing micro-inflammations.

Among the reasons for itchy scalp we find that dandruff is one of them, in fact, it is one of the main ones. The good side of this is that it can be solved in a simple way. We will explain how.

We should know that dandruff production starts with the overgrowth of a lipophilic yeast known as Malassezia. This is produced when there is an excess of oil on the scalp. That’s why many medical products are designed to control this large production of oils, allowing you to soothe the itchiness.

Read on to learn more about how to keep this problem under control.

Before we get to the possible solutions, it’s important to learn a little more about what causes all these symptoms and conditions on your scalp.

First of all, there is eczema.

Eczema is responsible for causing rashes and inflammations that occur on the scalp.

It can be caused by various factors such as stress or eating habits.

It has also been considered that the appearance of eczema is a consequence of allergic reactions to various types of cosmetics and soaps.

Seborrheic dermatitis.

This type of dermatitis is a medical condition that causes itching, irritation, and flaking of the scalp.

Experts often tend to confuse common dandruff with seborrhea. This is not a major problem, so you can rest assured. Its treatment consists of steroids, medical shampoos, and topical creams.

It is a totally treatable condition but it is necessary to see a dermatologist.


Another among the list of causes that produce scaling and burning is chronic psoriasis.

This occurs when our immune system creates an excessive production of cells on the scalp.

The area that is most affected by this is located around the root of the scalp.

This condition can be perfectly reduced with steroid-containing creams, oral medications, and medical shampoos.

You will probably notice considerable relief after the first wash.


It may seem unpleasant to talk about ringworm, but the truth is that tinea capitis is also involved in producing scalp irritation.

In addition to affecting other areas such as the feet, where it produces a bad odor, and the nails, causing them to rot, ringworm also reproduces on the scalp. It does this through towels, combing brushes, and pets. As a consequence, it can cause itching, flaking, and in some cases, hair loss.


If there is one parasite that is highly contagious and easy to spread, it is lice (as well as their eggs). This contamination can be achieved through brushes, clothes, hats, towels, headphones, hair accessories, among other things.

It is for this reason that it is considered significantly contagious because basically anyone can be affected or at risk. As if that were not enough, the itching produced by these parasites is extreme.

For their treatment, shampoos are used that have been pre-written by doctors. Some of them contain menthol, which helps to reduce itching.

Dry scalp.

As we have already mentioned, dryness is also a cause of itching.  This can occur in seasons such as winter, so it is always recommended to apply products that help moisturize the scalp.

Excess oil or grease on the scalp.

When hair is not washed regularly or too much oil or dirt accumulates, this causes irritation that can also lead to dandruff.

In the opposite case, we find that washing the hair in the wrong way affects the optimal development of cells in the scalp, which results in bad odor, itching, and flakes.

To treat these burns, there are cooling treatments.

It is crucial to completely remove conditioner residue, just as with shampoo.

If you need to dry your hair, avoid using very high temperatures because just as with hot water, this will make the problems worse. Use a medium or cool temperature if possible.

It is not recommended to wash your hair on a daily basis, remember that dryness is caused by a lack of natural oil, and by washing your hair constantly you prevent this oil from nourishing the hair, and in this case, this is what is needed.

Protect your scalp from the cold

The cold, either seasonal or drastic changes in temperature are sources of this problem, especially if the person has sensitive skin. To avoid this problem it is important to follow the recommendations we have already mentioned above, this will allow you to reduce all these collateral damages.

Careful when coloring your hair

Hair coloring has always been a process that can be harmful to the hair due to exposure to the chemicals used. Especially if you chose one that is not suitable for your skin type.

For this, you can go to an expert who will give you all the indications for the welfare of your health. It may be a little more expensive than usual, but it will always be better than suffering from these ailments.

Toners are an extra complement to scalp health. They are attributed to restorative and invigorating effects that strengthen the capillary structure, allowing to neutralize dandruff, brittleness, or greasiness.

This subject and its consequences have already been explained many times. It may seem that scratching the areas relieves the symptoms, but the consequences of scratching are notorious for irritating, inflaming, and producing wounds. Avoid scratching at all costs.

Visit a doctor if necessary

It is not necessary to wait for extremes to visit a professional. If you have any scalp discomfort, it is important to see a specialist who will tell you whether you should be concerned or not.
