Old Wives Tale

    Studies have shown that shaving has no influence on density or thickness of the hair. After all the follicle is quite a bit deeper than the skin surface.

   I believe this fiction stems from the onset of shaving occurring basically at the same time as the need to shave. As we approach and then propel into the teen years the terminal hairs darken and coarsen. This results in a need to shave. There is then the perception that shaving causes the changes in the hair

   Similarly, if a woman begins to develop darkening hair, more hair or coarse hair, the cause is hormonal; not because she began to use shave as a remedy to a more hirsute appearance. 

   Further, the act of shaving, causes the hair to be struck at an angle, making the hair feel sharper and more coarse.

Myth of shaving hair association with increased thickness & increased growth

This is a BIG myth & it is very difficult to make almost every patient to understand that there is no relation of shaving with increased growth/ or increased thickness of hair.

No matter, we shave or trim hair, it does not have any effect on its root deep inside the skin & the genetics which define the hair growth & hair thickness.

It is just a feeling that after shaving, base of the hair feels like more strong & broad for the short time but it is of same size & thickness as before.

Shaving is important before LASER as it helps to decrease chances of burning of skin.

Shaving does not cause a change in hair.

Shaving has earned this mythical reputation because natural hair left alone has a soft tip and has been exposed to light for a while, making it potentially lighter in color. Newly grown shaving stubble has a blunt end from the previous shave, and is just emerging into the light of day so it is as dark as it will ever be.

Do not be afraid to shave.

Shaving and excess hair.

Fortunately, you can shave, pluck, wax or nair unwanted hair, without causing more unwanted hair to grow. Think about it, with 75% of men experiencing some degree of permanent hair loss (male-patterned baldness) at some point in their lives, all they would need to do is shave their heads periodically to grow more hair. It just doesn't happen.

Shaving does not make your hair grow faster or thicker

It is a proven fallacy. Testing has shown that the growth of hair is not thicker or faster once shaving begins. Many patients prefer to wax as it gives a smoother result and lasts longer than shaving.

No

There is plenty of  clinical research showing that shaving has no effect on hair growth. All it does is that it makes the hair blunted, so that it appears thicker. Hair tapers at the ends naturally, giving it a finer appearance, but when you shave it cuts this tapered section off. That's why it looks thicker, but it will eventually taper off with time.

Shaving has no impact on hair growth or density.

The idea that shaving causes hair to grow back thicker or faster is one of the most persistent myths about hair removal. The appearance of hair and rate of regrowth is related to genetics, not your hair removal methods. There are two reasons hair stubble might look darker or coarser after shaving than before. First, a natural hair has a tapered end, while a shaved hair is cut across the diameter and has a blunt end, which makes it seem thicker. The other reason is because hair that’s been growing for a while is exposed to the sun and other elements that can fade the natural color somewhat. A shaved hair that’s growing back in hasn’t been exposed to these elements yet, so it stays darker. Waxing can be painful and is only temporary, so for long-term hair removal, I recommend looking into laser hair removal.

Shaving Does Not Make Your Hair Grow Thicker or Faster

Shaving has no effect on your hair growth. The only thing that it can do is make your hair look thicker. This is because when you cut the naturally tapered tips of each hair as you do when you shave, they become blunt and thus look thicker and darker.  

Shaving and hair growth

Shaving does not cause hair to grow back thicker nor faster. Shaving only affects the hair at the superficial layer of the skin, so it can't influence how it grows and it does not alter the actual follicle of hair beneath the skin. The hair follicle stays intact. Initially, when the hairs are growing out after shaving, they can appear/feel thicker due to the hairs growing out from the base. Once the hairs fully grow out to their original length, they should have the same thickness prior to shaving.

Does Shaving Make Your Hair Grow Back Thicker and Faster?

No it should not grow thicker. Tired of the traditional hair removal techniques, such as shaving, plucking, waxing and depilatory creams provide only temporary relief of unwanted hair.
