How Does Chlorine Affect Your Hair?
Chlorine, a chemical commonly used to disinfect swimming pools, can strip natural oils from your hair, leaving it dry, brittle, and prone to breakage. Prolonged exposure can weaken the hair structure, causing discoloration and split ends.
Key Effects of Chlorine on Hair:
- Strips moisture and natural oils
- Causes dryness and breakage
- Weakens hair cuticles
- Leads to discoloration (especially for dyed hair)

Who Is Most at Risk of Chlorine Hair Damage?
Certain hair types and conditions are more vulnerable to chlorine damage. Knowing if you’re at risk can help you take proactive steps to protect your hair.
High-Risk Groups Include:
- People with chemically treated or dyed hair
- Individuals with dry or brittle hair
- Frequent swimmers
- Those with fine or thin hair
