Whether your hair is dry or damaged depends on its elasticity and appearance. A simple strand test can help determine the difference.
The Strand Test
To perform a hair strand test, follow these steps:
- Take a single, wet strand of hair.
- Gently pull on both ends.
The results indicate the hair's condition:
- Stretches and returns to its original length: Your hair is healthy.
- Stretches but doesn't return to its original length: Your hair is dry. This indicates a lack of moisture.
- Doesn't stretch or stretches slightly before breaking: Your hair is damaged. This means the hair cuticle is compromised, resulting in porosity and potential breakage.
Visual Clues
Besides the strand test, observe your hair's appearance:
- Dry hair: Often appears dull, brittle, and may feel rough to the touch. It might lack shine and be prone to tangles.
- Damaged hair: Exhibits split ends, breakage, frizz, and may feel coarse or straw-like. It might appear dry but also could feel oddly brittle or crunchy. Damaged hair has compromised cuticles allowing moisture loss and vulnerability.
Key Differences
While dry hair lacks moisture, damaged hair has structural damage to the hair shaft itself. Dry hair can become damaged if left untreated. Dry hair can be improved with moisture treatments whereas damaged hair often needs protein treatments to repair the compromised hair shaft.
- Dry hair: Retains elasticity, even though it may lack moisture.
- Damaged hair: Loses elasticity and is prone to breakage.
