2 tablespoons liquid honey + 2 egg yolks + 1 tablespoon olive oil.
Olive oil and egg nourish the hair fiber, and honey repairs it. Egg yolk boosts shine.
1/ In a bowl, mix the honey and the egg yolks.
2/ Add the olive oil and whisk until you get a smooth paste.
3/ Apply the mixture to the lengths (finger or brush, more precise). Cover the hair with a towel and leave on for 20 minutes before rinsing thoroughly (to avoid the olive-egg scent once the hair is dry).
Immediate use.
