if you have taken small amounts of drug will hair follicle test show positive
yes, I just went in for my preemployment drug screening and they administered both a urine and hair follicle test
There are quite a few factors that go into the texture of a persons hair. The main factor of course is genetics, look to your parents to see their hair type and usually it will mimic yours. Other reasons include:Humidity in the airAll hair twists, even straight hair it just depends on the amount of twists.Hormones and medication can alter the texture of your hair and the way it grows.Shape and opening of the follicle: If you have curly hair, your hairs has a flat follicle. If you have straight hair, the follicle is round and on wavy they have an oval-shaped follicle.
No.
Cells at the end of a hair. They allow the hair to grow, just like the roots of a tree.
The part of the hair below the skin's surface is called the follicle. The hair follicle is essentially the root of the hair where it begins to grow just beneath the surface of the skin.
It is simply called a hair-follicle receptor. It is a free nerve ending which wraps around the hair within the skin, just above the follicle base.
If there is no bump, it is probably just an infection of the hair follicle. An infection or disturbance in the hair follicle can cause pain and discomfort in the area and when you move that piece of hair.
No. Hair does not conduct electricity. The germinative cells in the bottom of the follicle are the real enemy; hair is just the symptom. So, in order to kill the follicle you need destructive force at the bottom of the follicle such as with probe electrolysis or laser radiation.
It depends upon the person, genetics, age, hormone level and type of laser. If the amount of energy delivered to the area by a laser is high enough, which is measured in Joules per square centimeter, and the follicle has pigment, then the follicle will be destroyed. To remove hair permanently, the energy must by high enough to destroy both the follicle and the blood supply to the follicle, and then the hair will typically not grow back. Even with electrolysis or laser, if the hormone level is high the hair can grow back. And as everyone knows, sometimes as we age, the body just spontaneously sprouts new hair.
No. There's just not enough transfer.
Possibly, just the same as you can get sick from second hand tobacco smoke, if you breath in meth from the air in a room, it will show up in your body. It is best to avoid people and places involved with drug use.
You do which ever you prefer. Pulling the hair from the root (waxing, plucking) will make the hair grow back finer whereas just cutting it (shaving, hair removal cream) will just make it come back the same.
