## Why It Works
Egg yolk is approximately 30% fat and contains lecithin, a phospholipid that acts as an emulsifier and conditioning agent. The fat molecules coat the hair cuticle, smoothing it and reducing frizz. The proteins in the yolk also temporarily fill surface damage and porosity in the hair shaft. Olive oil reinforces this with additional fatty acids that penetrate the cortex of the hair. Together they produce a deep conditioning effect comparable to expensive hair masks.
## How to Do It
1. Separate 2 egg yolks into a small bowl.
2. Add 2 tablespoons of olive oil (or argan oil, or jojoba oil for finer hair).
3. Whisk together until combined.
4. Apply to dry hair — start at mid-length and work down to ends. Avoid the scalp if your scalp is oily.
5. Work through with fingers until fully distributed. A wide-tooth comb helps.
6. Wrap hair in a warm towel or shower cap to hold heat and improve penetration.
7. Leave for 20 minutes minimum (up to 30 for very dry hair).
8. Rinse with cool water. Shampoo once with a gentle shampoo to remove oil residue.
## Pro Tips
- Never rinse egg masks with hot water. The proteins denature at heat and you'll end up with cooked egg stuck in your hair. Cool or lukewarm only.
- Add a tablespoon of honey to this mask for additional humectant moisture. The honey also helps keep the mask from dripping.
- For fine hair: use only the yolks without the olive oil, or substitute a lighter oil like jojoba.
## When to Use This
When your hair is dry, brittle, heat-damaged, or just feels depleted. Once a month is about right for normal hair; once every two weeks for very dry or chemically treated hair.
