It's a common question with a simple answer: yes, leg hair does grow back after trimming. However, how quickly it grows back and the thickness of the regrowth varies from person to person.
There are a few things that can affect leg hair growth, such as hormones, age, ethnicity and even shaving techniques. For example, those with higher levels of testosterone may find that their hair grows back thicker and faster than others. Age can also play a role in hair growth; as we get older, our hair follicles tend to become thinner and produce less keratin (a protein that makes up our hair). This means that seniors may not see as much regrowth after trimming or shaving.
Ethnicity is another factor to consider when it comes to leg hair growth. Those of Asian descent typically have slower-growing, finer hairs while people of Caucasian or African descent usually have faster-growing, coarser hairs. Finally, shaving techniques can impact leg hair growth patterns. If you shave using a dull razor or shave against the grain of your hair, you're more likely to experience irritation which can lead to ingrown hairs and inflammation - both of which can impede regrowth.
So there you have it! Leg hair does grow back after being trimmed or shaved - but the rate and thickness of regrowth varies from person to person due to factors like hormones, age and ethnicity.
