The Structure of Your Hair
Before we dive into why your hair looks curly when wet and straight when dry, let’s first understand the structure of your hair. Your hair is made up of three layers: the cuticle, cortex, and medulla.
The cuticle is the outermost layer of your hair and protects the inner layers of your hair from damage. The cortex is the middle layer and contains the pigment that gives your hair its color. The medulla is the innermost layer and is only present in some hair types.
The shape of your hair is determined by the shape of the hair follicle. If your hair follicle is round, your hair will be straight. If your hair follicle is oval or flat, your hair will be curly or wavy.
The Impact of Water on Your Hair
When your hair is wet, it becomes more elastic and can stretch up to 50% of its original length. This is because water disrupts the hydrogen bonds in your hair, making it easier to manipulate.
When your hair is wet, the hydrogen bonds are broken, allowing your hair to take on a new shape. If your hair is naturally curly, the hydrogen bonds will reform in a curly pattern when your hair dries. If your hair is naturally straight, it will dry in a straight pattern.
The Drying Process
The way you dry your hair can also impact its shape. If you scrunch your hair while it’s wet, it will dry in a curly pattern. If you comb or brush your hair while it’s wet, it will dry in a straight pattern.
If you want to maintain your natural curls, it’s best to let your hair air dry or use a diffuser attachment on your hair dryer. If you want to straighten your hair, you can use a flat iron or blow dryer with a round brush.
Hair Care Tips
To keep your hair healthy and looking its best, it’s important to follow a good hair care routine. Here are some tips:
- Use a sulfate-free shampoo and conditioner to avoid stripping your hair of its natural oils.
- Avoid using hot styling tools on a daily basis as they can damage your hair.
- Deep condition your hair once a week to keep it hydrated.
- Trim your hair every 6-8 weeks to prevent split ends.
- Avoid using tight hair ties or hairstyles that pull on your hair as they can cause breakage.
