Premature graying of hair is often a great concern for younger adults in their 20s or 30s as gray hair make them look much older than they are.
The problem can be caused by factors like a genetic predisposition, poor nutrition, hormonal fluctuations, smoking, pollution, stress, use of unsuitable hair products, and certain diseases such as chronic colds, thyroid disorders, and sinusitis.
One of the major causes is the use of unsuitable hair products like hair dyes. Most hair dyes come in a pack of assembled chemicals with some containing hydrogen peroxide. Hydrogen peroxide in real life has many uses but is a bleaching factor in hair dyes. The downside is, hydrogen peroxide can accumulate in hair follicles and damage the cells responsible for imparting colour to your hair. These cells are called melanocytes. Once the cells are damaged, the result is the growth of hair from follicles that cannot color the hair strands.
Hydrogen peroxide is not the only chemical or substance that discolours hair or causes premature graying. Chemicals in some cheap hair dyes, undue exposure to sunlight, etc., can do similar damage.
However, with repeated, consistent dying, you not only stand a risk of premature graying but also of cancer. The chief ingredient in hair dyes is a known endocrine disruptor that can predispose to breast cancer.
You can dye your hair but remember to “Do all things in moderation!”
