Will It Always Grow Back

Yes and no.

We are genetically programmed (like balding) to have our hair grow and continue to grow up until a certain age. But what if we constantly pull it out?

Unfortunately, after many years of abuse, only about 60% of the hair will grow back. The rest might but will be weaker and thinner. Knowing this, it doesn't become any easier to pull less.

Drinking lots of water and taking multi-vitamins every day, apparently, speeds up the hair growth process (your nails grow a lot quicker as well). Eating healthy, of course, also contributes to faster and stronger hair growth. You can always tell a persons diet by their hair. Hair feeds off of blood, and depending on how many nutrients our blood carries (dependant on what we eat) it will show in our hair. People with very poor diets have thin, weak, and not so healthy looking hair. Versus nutritionists and people who lead a healthy lifestyle, who have silkier, shinier hair.

Then there are those bastards with amazing genes who can have the shittiest lifestyle, and the hair of a god.
