Firstly, lets explain why you have the type of hair that you do!
Why Do I Have this Type of Hair?
I'm sure at some point of time in our lives we have all uttered the words "Why do I have this type of Hair!?" and we probably wished for the opposite of what we have been blessed with. Well, the phrase "You were born with it" will fit perfectly here. Yes, your genetics is the main reason for your type of hair.

Researchers have been trying to completely understand why some hair are straight and others curly. Here are some of the common theories:
- Shape and opening of the follicle: If you have curly hair, your follicle is probably very flat in diameter. Straight-haired people have circular follicles. As for the wavy bunch? They have oval-shaped follicles.
- The number of twists per unit length: Even the straightest of hair twists as it grows. The more twists, the more curl.
- Humidity in the air: Hair, which is porous by nature, easily absorbs moisture molecules in the air, making the hair curl or frizz. Enough said.
- Hormones and medication: Changes to the shape of the follicle caused by hormones and medication can alter the texture of your hair and the way it grows.
- The position of the hair bulb in the follicle: The bulb is located at the bottom of the hair shaft. People with really curly hair may have a hooked end towards the bottom of the shaft, meaning their hair grows at more of an angle. Straight hair means little to no hook.
- The number of disulfide bonds in the hair: Simply put, the way protein structures are arranged in each hair shaft effect how hair behaves. The more disulfide bonds that occur between hair proteins, the curlier the hair and vice versa. This explains why you can temporarily alter the texture of your hair with heat and/or water — just by breaking bonds.
