Both thyroid hormones, T3 and T4, need to be at good levels for an individual to have healthy hair.
Hair and eyebrows are really ‘nonessential’, and if there’s a deficit of thyroid hormone, the body will skimp on the hair’s portion and allocate it to more important organs where it’s needed.
Good health is found when both Free T3 and Free T4 are in the upper half of the range. Hair cycles through a growth phase called anagen, a regression stage called catagen, a resting phase called telogen, and finally, the hair is shed in the last stage called exogen. You should take it into account. There’s probably a minimum degree of both T4 and T3 required for normal hair growth.
Those need to be tested and addressed you should keep in mind that. That T3 can not be tolerated in those with insufficient iron or cortisol levels.
You might need to add a small percentage of T3 to get your hair growing again, if you’re only on T4 or levothyroxine.
That means no new hair grows until there’s enough thyroid hormone to start the growth phase again. Hair loss is also reported by people with Graves’ Disease who are hyperthyroid, or on the T3 only protocol, or even on high doses of desiccated thyroid. Now pay attention please. Well unlike the hypothyroid body that’s in slow motion, a hyperthyroid body is moving at warp speed. Every strand of hair has a limited lifespan, and it progresses through all the stages sequentially. Fact, what’s the significant problem, they’ve got a lot of T3?
Accordingly the rate of the progression my be greatly increased in someone with quite similar way that it causes damage to other parts of the body. Test your estradiol and progesterone levels and consider bioidentical hormone replacement, if your hair started thinning around menopause. It started growing again and it got thick! For me T4 works better for hair growth and overall thickness…I was on synthroid for 16 years and never had a huge problem until I was put on cytomel. It got very dry, didn’t grow much. Seriously. T3 only and my hair got very much better. T4, or levothyroxine, seems to have a positive effect on many patients’ hair.
TMy hairdresser said my individual hair strands are thicker now. I have heard multiple anecdotal accounts reporting identical thing. Even pregnenolone can convert into testosterone in some women. Low thyroid hair loss is usually a general thinning throughout the entire scalp. Hair loss may also be caused by androgenic hormones like DHEA or testosterone, that contribute to androgenetic alopecia or male pattern baldness. That’s a male pattern hair type loss, that consists of a receding hairline and hair loss at the temples. So here’s a question. What exactly is required for good hair? So, like me, hair loss is brought up on both hyperthyroid and hypothyroid forums, and those who was both, have noticed their hair coming and going. Nevertheless, as with all supplements mentioned, be aware of adverse reactions. You shouldn’t ignore that supplement if your levels are low, vitamin D has positive effects on skin and hair too.
