Current Fallacy, Does Shaving Make Hair Grow Back Thicker?

When we remove unwanted hair from the leg using razor blades, we stretch the skin so that the blade can shave the hair, thinking that the hair will grow back thicker and darker rising into life again like a phoenix.

Amy McMichael, chair of the Department of Dermatology at Wake Forest Baptist Health, confirms that there is no science fact behind hair growing back thicker after shaving it, people pass on this myth because they are not good observers.

When a boy shaves his mustache and it grows back thicker, it might be by mere coincidence and coincides with the effect of natural hormones in his body, which increase hair growth during puberty, so shaving is not the cause.

Continues shaving and over shaving may make hair appear thicker for a short term. The end of the hair looks like the tapered tip of the pencil, so when the razor cuts it, the thick remaining part of the hair will appear darker.

Those short hairs left after shaving their tips will appear very near to their follicles, thus appearing thick, not because of any real change in the regrowth of the hair after shaving it. The tip of the hair that you cut off will grow again and look tapered again (we should point out that in some rare cases, removing hair from the roots by waxing makes it grow from other follicles.)

The medical literature has tackled this issue, and compared between natural hair growth and hair regrowth after shaving. In 1928, a study was done on four men – after getting their consent – where they shaved their beards using razor blades and moisturizer at a constant temperature.

After following up with them, the researchers found that there is no scientific evidence that shaving accelerates the growth of the beard.

In a recent study done on five white men to check whether the hair growth multiplies after repeated shaving, each volunteer shaved one leg weekly for a month, and left the hair on the other leg to grow naturally.

The result was that there is no difference between the two legs in terms of thickness, coarseness or growth rate.

The dermatologist Melanie Grossman says that women shave their legs constantly, and if the hair grows thicker and darker, they would look like gorillas. Amy McMichael says that we would never care about hair loss in the heads if the hair would grow again thicker.

Hair waxing is similar, whereas hair doesn't grow thicker after removing it from the roots. We should not forget the genetic and hormonal influence on hair growth, and the surrounding environment plays a role as well.

Amy McMichael says that if you pinch an area of your skin roughly, it will become rough and coarse, the hair may look thicker, and the nerves may get thicker, as well as everything else in that area.

There's another factor that may explain why the hair appears thick when it grows back after shaving it, it's because it's not been exposed to tanning factors and the sun, therefore it looks thick and dark under the light.

So, let's stop this myth from spreading out and passing down to the generations because there is no scientific evidence proving it.

To sum up, many of us think that shaving hair using the blade would make it grow back thicker, but the researchers have done some trials that deny the authenticity of this saying and confirm that sometimes it grows back thicker by mere coincidence.
