Myth or truth: Does shaving your hair make them grow thicker?

Many people have probably heard this from someone: if you cut their hair, it will always grow thicker and darker. But is this fact true, or is it one of those myths passed down through generations and without any foundation?

We shave, trim the hair, in some cases we shave, all in order to prevent the hair from manifesting in the fertile soil that is our body. If the phoenix is ​​reborn from the ashes, our hair will always be reborn after it is cut and it seems to become more and more insistent.

However, according to studies by Amy McMichael of the Wake Forest Baptist Health Institute's Department of Dermatology, hair does not grow thicker when it is clipped. "People just aren't good observers, as there is no scientific evidence that their hair grows thicker, " McMichael said. However, it is important to note that in some cases this may be partly true, but for other reasons rather than the haircut itself - which is why the myth persists.

For example, if a boy shaves his growing mustache, his hair will grow somewhat stronger - but this is due to the hormonal acceleration of the body when adult hairs manifest on the young man's face. The body's hair grows according to age and in different regions, so it is regulated by hormones rather than shaving or shaving. In that case, shaving can wake up these hormones.

Bigger and thicker beards after shaving?

It is true that cutting hair, whether it is men who shave or women who trim their hair on their legs and armpits, can make them look thicker when they get bigger. However, this is due to the hair being cut in half (and not pulled out by the root, as in hair removal), so that the unseen parts under the skin grow and manifest.

Make no mistake: what you cut for is exactly the same as it will be born later. Nevertheless, it is true that the hair removal process, if repeated thoroughly, can eventually reduce the growth of hair follicles as the hairs are removed at the root. A study done in 1928 compared the level of hair growth in men, and four individuals were analyzed by shaving their faces under the same conditions.

The hair grows the same way

The facial hair that grew on shaven and untouched areas was exactly the same size: neither thicker nor larger. All hairs were measured and there was no evidence that shaving can increase the growth rate of beards. Another more recent study, from 1970, decided to analyze the impact of cut hair frequently on our body. Five men agreed to participate in the study, with their right legs constantly trimmed and their left legs intact.

After months, the degree of growth and thickness in both legs was equal, without significant differences. Melanie Grossman, a New York dermatologist, demystified the myths of thicker, darker hair by simply saying, “Women shave all the time. Today we would be gorillas if the hairs were growing darker and stronger. Also, if that were true, we wouldn't have to worry about hair loss, as we always get our hair cut too. ”
