Scalp: everything you need to know!

Certainly, you have already received several tips on the best  hair treatment . But what  about taking care of your scalp?  Whether in the beauty salon, in conversations with friends or even with some recipes that pass from generation to generation: everyone has a series of infallible tips.

However, you need to know that, among these miraculous and unusual tips, there are several pitfalls! Therefore, so that you do not fall into any of them, it is essential to have a deeper knowledge about this universe.

If you don’t understand very well, rest assured! We will teach everything! Come on?

Understand what is scalp

First, we need to talk a little about the physiognomy of the scalp (even if we have to talk about more technical terms). See: we can define the scalp as the set of soft tissues that cover the skull – in other words, much more general, it is the skin that covers the skull and has hair!

This coating is divided into five layers. However, the first three are called scalp (precisely because they are so close together). Understand what they are:

  1. Scalp with three layers:
  • skin (epidermis and dermis);
  • dense connective tissue (composed of adipose and dense fibrous beams) and;
  • aponeurotic galea.
  1. Loose connective tissue.
  2. Periosteum or pericranium.

The scalp has fundamental functions in our body. It serves as a physical barrier, thermal insulator and also as immunological protection.

It is noteworthy that in the scalp there is a very vascularized structure, composed of a branch of several blood vessels. They are responsible for bleeding in the head (in this case, when there are injuries in that region, the wounds need to be immediately saturated to avoid the formation of bruises).

What is cell renewal?

When we talk about scalp, we cannot fail to mention the importance of cell renewal.

Cell renewal takes place every 14 days, however, when there is some kind of injury or inflammation, this process is accelerated. Although it seems like an extended period, for you to have an idea, the renewal of skin cells is much slower: it happens every 21 days.

This renewal must be done because there are several dead cells. Extremely small scales are not visible and must be eliminated. However, when there is some kind of hyper desquamation or inflammation, these dead cells accumulate and become visible, becoming the evil that everyone fears: the terrible dandruff!

Understand how the hair cycle works

According to some scientific articles

, the biological cycle of hair has three phases:

  • Anagen:responsible for active hair growth (lasts 3 to 6 years);
  • Catagen:when the hair begins to die (lasts 3 weeks);
  • Telogen:when the hair is killed and pushed by a new anagen thread (lasts 3 months).

Learn more about sensitive scalp

Most likely you have heard of someone with a sensitive scalp, right? This means that any small pressure in that region is already a total discomfort.

It is very common for people to experience pain or some kind of sensitivity in this region. Therefore, if you feel that your scalp is sensitized, it is essential to assess the cause to perform the most appropriate treatment. That’s because it can be a sign of a more serious problem.

Know what causes sensitive scalp

There are several causes for sensitive scalp. Therefore, it is necessary to identify your case to avoid further complications. See what they are:

Solar Exhibition

It happens when people don’t use capillary sunscreen and expose themselves to the sun. This mainly happens with people who have baldness or have transparency and flaws in their hair.

Excess oil

People who have excess oil on their skin may also experience discomfort from the sensitive scalp. This is because seborrheic dermatitis (dandruff) leaves the area more sensitive and painful.

Chemistry

People who perform chemical procedures (straightening, relaxing, dyeing) may have sensitized leather. This is because some chemicals can ignite or even burn. It is very important to note that some of these procedures can cause irreversible damage.

Treatments for sensitive scalp

To have a healthy scalp, it is possible to invest in some simple habits.

  • Use capillary sunscreen;
  • Avoid direct sun exposure between 10 am and 4 pm;
  • Wear a hat (but never use pressure on your head);
  • Use the hair dryer at an average temperature and a distance of 30cm;
  • avoid using chemistry.

We emphasize that it is always very important to see a dermatologist. Only he will be able to identify your problem and prescribe the best treatment.

Find out what are scalp diseases

There are several diseases and pathologies that can affect the scalp.

None of them presents serious health risks, however, they present emotional insecurity and loss of self-esteem – factors that directly influence quality of life.

Seborrheic dermatitis

Seborrheic dermatitis is the best known of capillary diseases, popularly called dandruff. It is related to the production of sebum by the sebaceous glands. Another factor that can cause the disease is the proliferation of fungi and bacteria that cause an inflammatory response. In that case, reddish regions appear on the skin along with itching.

There are other factors that can cause seborrheic dermatitis, such as:

  • Genetics;
  • Allergies;
  • Emotional stress;
  • Alcoholic beverages;
  • Some types of medication;
  • Excess oil.

It is worth mentioning that the disease is not contagious, either, caused by the lack of hygiene in the place.

Treatment  for seborrheic dermatitis

The monitoring of a dermatologist is essential to observe the evolution of the disease and also to help identify the cause. In general, it is recommended to use appropriate and specific shampoos, 3 to 4 times a week.

Psoriasis

According to Ricardo Romiti , dermatologist at the Brazilian Association of Dermatology, psoriasis is related to the immune system and also to genetics. In these cases, they present red and scaly plaques that appear through the body. Usually, it stands out in regions such as the knee, elbows and scalp. Psoriasis is not a contagious disease.
