Why is my hair straight when its naturally curly?
That shape depends on the shape of the hair follicle. This tiny structure guides the hair fiber up a sort of tube as it grows. The inside of the tube determines if the hair is curly or straight — ovals produce curly hair and circular tubes yield straight hair.
Why does wavy hair look straight when wet hydrogen?
Water is made of hydrogen and oxygen—it’s called H2O because every molecule of water has two hydrogen atoms (H2) and an oxygen atom (O). When you wet your hair, water molecules sneak in between the proteins of the cortex and join these hydrogen bonds. That’s also why you can curl your hair when it’s wet.
Why is my hair flat when wet?
When your hair is wet, it is weighed down at the roots. If you allow your hair to dry this way then you’re likely to experience flatness, so one way to avoid the wet dog look is by plopping.

“Humidity is moisture in the air: it breaks the hydrogen bonds, causes the hair to swell a little bit, and that means the hair becomes wavy or frizzy when it dries in its new shape.”
Why is my straight hair suddenly Curly?
People often see changes in their hair texture when they go through puberty, and hormones are probably one reason for this. Women going through pregnancy often notice changes to both their skin and hair. Pregnancy hormones play a role in these changes, so may possibly play a role in straight hair suddenly turning curly.
Why does my hair curl up when it gets wet?
Things like temperature and sun exposure can affect hormone levels, so that maybe what’s going on. Or it could be the new climate directly affecting your hair. Just as curly hairs typically curl the most when wet, humidity in the air brings out waves or curls in hair.
How does the shaft of your hair affect how curly it is?
The shaft of your hair affects how curly it is because of the way protein molecules build up. Proteins such as keratins tend to build up unevenly in curly hair, collecting in the curve of your hair, make it curl even more.
Why does my hair curl when it’s oval?
“When it’s oval, one side is curved and the other side is flat, which makes it curl.” So if your hair changes from straight to curly it suggests that the follicles must be changing, but Mirmirani couldn’t tell me why that would happen, though she thought it could have something to do with hormones.
