I found a gray hair this morning during my daily hair styling routine. I thought it was just a piece of lint or something until I noticed a bulb at the end of it. I'm only 24! Is that normal?
Premature graying is normal. I discovered a couple gray hairs about 3 months ago and I'm 32. I thought it was a cat hair as I had recently been caring for my neighbors kittens. I told my mom and she just laughed about it. She told me my dad had a few strands when they married (they were in their late 20s).
Since you're only 24, its not time to worry about a few gray hairs! You've got about 20 more years of hair growing before the grays start to come in.
Its a natural part of the aging process.
You are right. It is a mineral deficiency. When you replace the missing minerals, your hair will start to regain its pigment. It is actually pretty cool to see.
