yes, mammels that live under water, such as the dolphin, grow hair as well as birth live young and other traits that are possessed by mammels
Only mammals grow hair on their body. No other animals grow hair.
They grow from hair follicles under your skin.
yes
Puberty
something LoL!
Drinking water is healthy for your body, but will not make your hair grow any faster or longer. Hair growth is determined by the hair follicles.
No. Considering that hair grows from the follicle and not at the tip then, in a manner of speaking, hair is always growing under your hair, however, it doesn't form a "second layer" of hair but merely extends the current one.
The cheapest way to grow your hair out is by using warm/hot water on your hair when you wash it. :)
Yes healthy food and water helps your hair grow homie
puberty
About 1-2 years after you start puberty, you start to grow hair under your arms and around your genitals.
