Chlorine is essential for water disinfection, but it is a harsh chemical for hair. It dries out hair fibers, causing discoloration and structural damage.
Visible effects
- Greening of light hair: Chlorine reacts with copper in water
- Dry texture: Chlorine removes natural oils
- Dull hair: Cuticle damage
- Brittleness: Weakening of hair
Prevention before swimming
1. Wet your hair with clean water
Hair absorbs the first liquid it comes into contact with. If you wet your hair with clean water, it will absorb less chlorine.
2. Apply a protective layer
- Coconut oil: Creates a hydrophobic barrier
- Leave-in conditioner: Special formula for swimmers
- Protective pre-swim spray
3. Wear a swimming cap
The silicone cap significantly reduces the contact of the hair with chlorine.
After swimming care
Immediate rinsing
Within 15 minutes after the pool you should rinse your hair thoroughly.
Proper procedure
- Rinse with clean water (2-3 minutes)
- Apply swimmers shampoo
- Deep conditioner (5-10 minutes)
- Cold rinse
Swimmers shampoo
Ordinary shampoo will not remove chlorine effectively. Swimmers shampoo contains:
- EDTA (chelators): Weighs chlorine and minerals
- Vitamin C: Neutralizes chlorine
- Keratin: Repairs damage
Home alternative
1 tablespoon baking soda + normal shampoo = removes chlorine. Rinse with vinegar water (1:4) = it restores the pH.
Deep hydration
If you swim several times a week:
- Deep hydration mask: 1x a week
- Coconut oil overnight
- Protein treatment: Every 2 weeks
Green hair – solution
Chlorine itself does not turn hair green – copper in the water is to blame.
How to remove
- Vitamin C tablets + shampoo: Leave for 10 minutes
- Ketchup mask: Red pigment neutralizes green
- Chelate shampoo
Products for swimmers
- Swimmers shampoo or chelate shampoo
- Deep moisturizing conditioner
- Pre-swim protective conditioner
- Leave-in conditioner
- Quality silicone cap
