What causes hair to be curly or straight??

My hair is kind of curly and a little wavy. What do people with straight hair have that people with curly hair dont have?? And what do people with curly or wavy hair have that people with straight hair dont have?? Im just curious because I see lots of people with blonde hair, and their hair happens to be straight, but people with black or brown hair happen to straighten it alot and it's mostly curly.Why is that?? My hair is light, light brown with golden streaks.It's very smooth when I straighten it.My hair barely falls out. HOW CAN I GET MY HAIR TO BE SMOOTHER AND MORE VIBRANT WITHOUT STRAITENING IT? Thank you for answering both of my questions, the main question and the detailed question.

What causes hair to be curly or straight??

Two things cause curly/staight hair...genetics and hair weight. Curly hair is caused when the hair grows from the folicle with one side being slighly longer than the other (the smaller the curl the more pronounced the length difference) on some people causing it to curl or wave. (just imagine taking a string, folding it in half, twisting it, and pusing one side up so that it curls tighly around the other half of the string.) The other is because of weight. I have long blonde hair and when it is short it's very curly but right now it's straight because it's so long. If I curl my hair it still falls very fast even with hair spray because of it.

Here are some ways to staighen your hair without using a flatiron. If you blow dry your hair while brushing it and using a light spray that might help. Don't braid your hair or put it in a bun constantly! Some people don't realize that certain hairdo's "train" hair to be wavy and curly. Always use a good conditioner too with antifriz...the dryer it is the "poofier" it gets. (Garnier has the Antifriz and Long and Srong lines that I highly recomend for hair protection and smoothness.)

YOUR question winner, doesnt know. If you have a follicle that is straight up and down from the scalp, straight hair. If it is from the scalp and curving left or right, wavy or curly hair. If it is from the scalp and going hard left or right, very curly hair. Thats all it is. Report It

What causes hair to be curly or straight??

Scientifically, whether the hair itself is round or oval in shape makes it straight or curly. Has nothing to do with the color of the hair. Extremely curly hair tends to be dry. So you might want to try different shampoos and conditioners. Use a conditioner intended to be used while combing it out as you are drying with a hair drier.

What causes hair to be curly or straight??

The differences between wavy and straight hair have to do with the hair follicles on your head. People with straight hair have regularly shaped 'pores' on their head, creating an even growth in the shape of their strands of hair. Curly hair, on the other hand, has to come out of an irregularly shaped 'pore'. The hair grows in such a way that it bends the strand to a curl or wave. It is actually considered to be a sort of defect. The reason straight hair is shiny, it just because it is able to reflect more life due to its constant line. Curly hair will not tend to reflect more light in the areas that are concave (inwards) because it is not receiving enough light to reflect. It is just the hand you were dealt with.
