Gray and white hair are a natural part of aging, but many people prefer to soften the appearance of gray roots without using permanent hair dye. This has made homemade recipes using ingredients such as coffee, cocoa, black tea, and other natural products extremely popular.
The viral claim that a brown paste can “bury white hair at the root” in just 12 minutes and permanently lock the color into the hair is misleading. A homemade paste cannot permanently reverse gray hair or change the pigment produced by the hair follicle. However, some natural ingredients can temporarily stain or darken the surface of the hair, making gray strands less noticeable.
Why Does Hair Turn Gray?
Hair gets its natural color from a pigment called melanin, which is produced by specialized cells inside the hair follicle.
As we age, these cells can become less active and eventually produce less pigment. As a result, newly growing hair can appear:
- Gray
- Silver
- White
Once a strand has grown out gray because the follicle is producing little or no pigment, applying a food-based paste to the hair shaft cannot make the follicle permanently start producing melanin again.
Can Coffee Darken Gray Hair?
Coffee is one of the most popular ingredients in homemade hair-coloring recipes.
Coffee contains dark pigments that can temporarily stain the outside of the hair. The effect is generally more noticeable on lighter or porous hair and much less dramatic on naturally dark hair.
However, coffee does not permanently restore natural hair pigment.
The color gradually fades as the hair is washed.
