Foods to eat for hair growth, known as nutricosmetics, are edible substances that nourish hair from the inside out. Biotin-rich egg yolks are a prime example.
Nutricosmetics are gaining popularity due to their ability to address hair concerns beyond topical treatments. Their benefits include strengthening the hair shaft, promoting scalp health, and reducing hair loss. Historically, the use of foods for hair growth can be traced back to ancient Egyptian and Chinese traditions.
