Have you ever wondered why your hair stands on end? On certain occasions the hair on our body, mainly on the arms, stands up involuntarily, but what is the reason?
The reasons why our body sometimes reacts with the famous “hair on end” go back thousands of years. Next we tell you why the hair stands on end and what this popular phrase really means.
More or less frequently we have experienced how the hair on our body stands on end in very specific situations. It is a completely involuntary event that we can never control, but what does this mean?
When we say that our hair stands on end, we are really referring to the hair follicle cell reaction triggered by the sympathetic nervous system. This activity of the follicle, together with a muscular contraction, cause the elevation of the hairs which is called piloerection.
Therefore, behind the famous phrase "my hair stands on end" there is a cellular and muscular activity in our body. But why do the hairs stand on end? What are the main reasons why our body reacts in this way?
As we mentioned before, the reasons why an involuntary capillary activity of this style occurs dates back thousands of years. It is said that we have inherited this function from our ancestors, whose hair stood on end to appear larger to a predator. This also occurs in other species such as cats.
However, today our skin crawls for two very specific reasons. Why do our hair stand on end? Continue reading!
In the coldest times of the year we notice that our skin bristles more and piloerection occurs more frequently. This has an explanation.
For reasons of survival, when our body perceives a drop in temperature, the brain sends a nerve signal to the hair follicles, which rise up favoring the distribution of air currents. Ultimately, it is a natural way to maintain body heat.
Another factor that explains why the hair stands on end has to do with emotions. Faced with certain stimuli such as nervous situations, fear or emotion, it is, in these cases, the involuntary release of adrenaline which causes piloerection.
In the same way that our hair stands on end, there are many other hair curiosities that you didn't even know. Did you know that hair has memory? Or that the hair is actually "dead"?
Although there are many curious facts about it, we must bear in mind that there are also many hair fake news that circulate Do not be fooled!
Hair is a key part in the aesthetics of men and women. Daily we brush, wash and condition it so that it looks perfect. However, intense hair loss can lower our self-esteem by causing areas without hair or a considerable lack of density. To stop the advance of a alopecia, it is essential to go to a specialized hair clinic where, in addition to receiving a personalized diagnosis, they will recommend how to proceed.
En Hospital Capilar We are experts in medicine and hair surgeries. With presence in Madrid, Murcia and Pontevedra we have medical hair treatments aimed at stopping hair loss and improving its quality, and we also perform hair grafts daily.
Thanks to capillary analysis Before our medical team performs, it is determined which one or the other is the most appropriate, or both combined.
En Hospital Capilar we have the Hair Redensification Treatment, or HRT, which stops hair loss by combining adapted drugs and vitamins. It is a subdermal application treatment on the scalp through almost painless microinjections.
On the other hand, there is the Capillary Regeneration Treatment, or CRT. It is a treatment, also for subdermal application, that promotes hair regeneration thanks to the rich growth factors contained in the patient's own blood plasma.
The maintenance hair treatments mentioned above are perfect for stopping hair loss and maintaining it. However, in no case will they make hair grow back in those areas where it stopped growing naturally. The only method to recover lost hair due to alopecia is hair grafting in Spain.
It is an outpatient, minimally invasive technique that leaves no visible scars. It consists of the individual extraction of the follicular units from the area that is not affected by alopecia to subsequently implant them in the recipient area. For this, local anesthesia is used, and in Hospital Capilar we have a pre-anesthesia service with which we considerably reduce the pain of the injections of the anesthesia itself.
The definitive results are given one year after the FUE capillary implant, although at 6 months the first changes can already be seen.
