As soon as I got the symptoms of hypothyroidism 2 years ago I had a sudden onset of grey hairs. I had a full head of black hair before being hypo, not 1 white hair.
I still haven't been given meds for the hypo as the doctors say the blood test results are slightly abnormal only but I have many symptoms of being hypo so I am seeing a private doctor in January.
My main question is, if the hypothyroid is corrected, will the grey hairs become black again? I have about 25 white hairs now over the course of 2 years of being hypo.
Thyroid hormones require the amino acid tyrosine for their production. So low levels of tyrosine can lead to hypothyroidism. Tyrosine is also required for the production of melanin, which is used to pigment hair and skin. So a lack of tyrosine can also lead to premature graying.
The other possibility is that the hypothyroidism is autoimmune in nature. If a person has an autoimmune condition they are more prone to other autoimmune conditions. And pigment cells can be destroyed in some autoimmune conditions.
What about minerals HV? I've read that the loss of hair color can have to do with the body using minerals from the hair that it feels it needs. Your thoughts?
I disagree with that claim, but the other common cause of premature graying is copper deficiencies. But if occurring at the same time as the onset of hypothyroidism then the lack of tyrosine would be more likely than a copper deficiency.
So, hypothetically, IF tyrosine is the problem then supplementing with tyrosine tablets will cause my grey hairs to return to their original colour or would correcting the hypothyroid correct tyrosine levels by the thyroid itself?
Since tyrosine is needed for thyroid hormone production low tyrosine could also lead to hypothyroidism. Therefore, if low tyrosine is causing the hypothyroidism and the gray hair then tyrosine supplementation should help with both. It does take a while though for the new pigmented hair to grow out.
By the way tyrosine should be taken on an empty stomach at least 30 minutes before meals.
