The primary component inside your hair is keratin, a strong protein.
Understanding Hair Structure
Your hair isn't just a simple strand; it's a complex structure primarily made of a protein called keratin. Let's break down what this means and how it contributes to the hair's properties:
Keratin: The Building Block
- What is Keratin? Keratin is a fibrous, helix-shaped (spiral) protein. This unique shape contributes to its strength and flexibility.
- Where is it Found? Keratin is the main protein in skin and all its appendages such as hair, nails, and body hair. According to provided references, hair is composed of 95% keratin.
- How is it Made? Keratin is synthesized by cells called keratinocytes.
- Water Resistance: Keratin is insoluble in water, this property is what makes hair impermeable and gives it protection.
Table Summarizing Hair Composition
| Component | Description | Function |
|---|---|---|
| Keratin | Fibrous, helical protein, 95% of hair structure | Strength, impermeability, and protection for hair |
| Keratinocytes | Cells that synthesize keratin | Production of keratin protein |
Practical Implications
Understanding the importance of keratin helps us appreciate the structural properties of our hair. Here are a few practical points:
- Strength: The high keratin content makes hair resilient to everyday wear and tear.
- Protection: Hair is able to protect your scalp from the sun due to keratin.
- Water Resistance: Hair repels water, which helps maintain its shape and reduces moisture damage.
In summary, the core of your hair is composed of keratin, which gives it strength, flexibility, and water resistance.
