Overview
Philip Kingsley Swimcap Water Resistant Mask is the original professional pre-swim hair protector. Created specifically for the US Olympic Synchronized Swimming Team, it forms a water-resistant barrier using castor and olive oils, preventing chlorine, salt water, and sun damage from penetrating the hair shaft.
Key Ingredients Breakdown
- Ricinus Communis Seed Oil (Castor Oil) - Creates a thick, water-resistant barrier that prevents pool water from penetrating the hair shaft.
- Olea Europaea Fruit Oil (Olive Oil) - Rich in vitamin E and essential fatty acids, locks in moisture and boosts shine.
- Hydrolyzed Elastin - Adds strength, body, and elasticity to reduce breakage.
- Dimethicone - Creates an additional protective barrier against water.
- Ethylhexyl Dimethyl PABA - UV filter that protects hair from sun damage during outdoor swimming.
What We Love
- Professional pedigree - Created for Olympic athletes
- Genuine water resistance - The oil barrier actually works
- UV protection - Shields from sun damage too
- Strengthening - Elastin adds elasticity and reduces breakage
- Multi-purpose - Works for pool, sea, and sun exposure
What Could Be Better
- Contains silicones - Dimethicone means this isn’t CGM-friendly
- Contains protein - Hydrolyzed elastin may not suit protein-sensitive hair
- Premium pricing - Significantly more expensive than DIY oil alternatives
- Requires clarifying - Need to properly remove after swimming
- Can weigh down fine hair - The oil-heavy formula may be too much
How to Use
Pre-Swim Application
- Apply to dry hair before swimming
- Work through from roots to ends
- Pay extra attention to ends and any previously damaged areas
- Secure under a swim cap for maximum protection
- Swim as normal
- Shampoo thoroughly afterward—clarifying shampoo recommended
For Beach Days
Apply before sun exposure for combined UV and salt water protection. Reapply if you’ll be in and out of water throughout the day.
The Verdict
As a premium pre-swim protector, Philip Kingsley Swimcap delivers professional-grade protection. The Olympic heritage is genuine, and the water-resistant barrier works. However, the silicone and protein content means it’s not suitable for CGM followers or protein-sensitive hair. For serious swimmers who prioritise protection over ingredient purity, it’s the best in class.
