This everyday ingredient, accessible to everyone, made hair luminous without damaging it.
Long before pearly bottles and silicone formulas, our ancestors had their secret for shiny hair. This forgotten ingredient, although present in all kitchens, worked wonders without damaging the hair fiber.
Our grandmothers knew it: a simple ingredient, beaten and applied to wet hair, left hair supple and luminous, without the cardboard effect of industrial detergents. Less cleansing than modern shampoos, but incredibly nourishing, it coats and shines thanks to its proteins and lecithin. The sebum remained balanced, the cuticle closed naturally, the light was reflected. Result: a soft, authentic shine that lasted. That treasure hidden in the fridge? Egg yolk.
To use it, nothing could be simpler. Beat one or two egg yolks (depending on the length of the hair) with a little lukewarm water to thin the mixture. Apply to wet hair, from roots to ends, gently massaging the scalp. Leave it on for a few minutes, then rinse thoroughly with lukewarm water, never hot, to prevent the egg from coagulating. A final rinse with cool or vinegar water closes the scales and reinforces shine.
Some added a spoonful of olive oil for very dry hair, or a little lemon juice for oily hair. Others alternated: a wash with diluted Marseille soap to clean, then egg yolk as a treatment to nourish and shine. The advantage? No suffocating silicones, no stripping sulfates: the hair regains its natural rhythm, its original texture.
This ancestral gesture returns to zero waste routines. The cost? Around 30 cents per organic egg yolk, compared to 5 to 15 euros per bottle of shampoo. A box of six eggs allows for several washes, and the quality-price ratio is unbeatable. A practice from another time which reminds us that our ancestors knew how to take care of themselves with intelligence and simplicity.
Faced with the fatigue of chemical formulas, these old gestures are attractive again. Egg yolk, Marseille soap, rinsing vinegar… So many simple recipes which remind us that shine has nothing to do with marketing, but everything to do with balance. Clean, healthy and respected hair reflects light better than any serum.
