What Does Your Hair Tell About You?

What Does Your Hair Tell About You?

Once a hair comes out of the scalp, it's dead. Delightful thought, no? Even though hair outside of the scalp is no longer living, scientists can still tell a lot about a person just from analyzing his or her strands.

Your hair, which grows about a half-inch per month, comes out from living follicles from within the scalp, so whatever you put in your body becomes pretty much trapped "evidence" within. For an accurate drug analysis, for instance, it's typical for scientists to look at about one and a half inches of hair (about 90 days' worth) towards the newer growth. That's why hardcore drug users often shave their heads — to avoid detection.

Hair analysis can also tell approximately where you live, your exposure to chemicals, your DNA information, if you drink, and your eating habits. One thing hair can't reveal? Surprisingly, it can't tell your gender, according to the FBI — and the g-men should know. Did you ever think that your hair was like a living diary? Turns out, it is.

If they can get your DNA, they can tell your gender. That fact doesn't make any sense... Unless you were trying to say from just looking at the hair?

Skigurl Not all topmodels have long hair! Freja Beha Erichsen has short androgynous hair and that looks fab on her!

"That's why hardcore drug users often shave their heads — to avoid detection. " LOL this is probably common among paranoid crackheads...I doubt the cops would waste the money on a hair strand drug test unless it was absolutely necessary....and definitely not for your regular job interview drug test!!!

my hair grows 1.5 inches a month, sometimes 2. it's way annoying, as i have to colour it every 2 weeks and by the end ot those two weeks i look terrible, i'm platinum blonde and my real colour is dark brown.

Hair Analysis can also be used to check a person's Health. Professional athletes get their hair analysis to check their nutrient level so they can perform at their best. Hair sampling can be done at home and sent to the lab like for analysis. Once the analysis is complete, it is a good idea to have an experienced professional review the results and make recommendations.

yeah, I learned this. This is why Hair vitamins work. Obviously what you put into your body affect your hair in a big way.

Wasn't that why Britney shaved her hair like 2 yrs ago. She was in that custody battle for her kids and she didn't want anything about drug use coming up? At least that's the rumor I heard.

Short hair rocks! I think it's so lame when people try to use "guys like long haired girls" as a reason why I should not cut my hair. I look damn hott with a short Twiggy haircut. It also makes me feel fearless, which is more attractive than resembling Cousin It.

This fact has always been the reason why I cut my hair after bad break-ups/bad events in my life. I like to make a clear cut from the negative ... literally.

It can tell all that but still can't tell your gender? How odd.

i totally thought this article was going to talk about styles and fashion and personality i view myself as a long haired girl. i don't think i suit a shorter haircut and i look much better with length and the closer to my shoulder i get, the fatter i look i also think that if you're single and looking for a man, longer hair is the way to go. in "he's just not that into you" i really didn't think that ginnifer goodwin's short haircut was doing her any favors looking for a man. 20-something single men like long hair...think about it. guys don't get fashion or trendy anything...they get hottness.
