No, it is not true that hair grows back thicker after shaving. This is a common myth, but there is no scientific evidence to support it.
When you shave, you are cutting the hair at the surface of the skin, which can create a blunt tip that feels stubbly as it grows back. However, this does not change the thickness or texture of the hair, and it will eventually grow back to its natural thickness.
It's important to use a clean, sharp razor and shaving cream or gel to help prevent irritation, razor burn, and ingrown hairs. Take your time, shave in the direction of hair growth, and be gentle to avoid nicks and cuts.
If you're concerned about the appearance of hair regrowth or want a longer-lasting hair removal method, there are other options such as waxing, threading, or using depilatory creams. However, it's important to be aware that these methods can also cause irritation or sensitivity in some people, and may not be suitable for everyone.
