A relentless loss of eyebrows can be a distressing experience and may lead to an ongoing attempt to get them to regrow somehow. But it may not be all doom and gloom because sometimes eyebrow thinning can be a warning that there is some other problem in your body.
Your thinning eyebrows may be a blessing in disguise because it might pinpoint that you have a thyroid problem.
Treating Hypothyroidism May reverse Eyebrow Loss
A connection has been made between the thyroid and thinning eyebrows. If the thyroid is under-active, known as hypothyroidism, it won’t be producing enough hormones – thyroxine (T4) and triiodothyronine (T3) and the growth cycle of the hair will be disrupted. This can result in too many follicles being placed into a resting state which manifests itself, among other things, as thinning eyebrow hair, particularly at the outsides of the eyebrows.
The first step you should take when you notice that there is thinning to the outside edges of your eyebrows is to go to the doctor to have a thyroid check. The recommended test for hypothyroidism is called a Thyroid Stimulating Hormone (TSH) test however this won’t provide a complete picture of the problem. For a thorough test of a thyroid problem to get the full picture Free T4 and Free T3 tests should also be performed.
When treating hypothyroidism you need to replace the thyroid hormone that is lacking. One of the most commonly used medication is levothyroxine for T4 and there have been reports from people who have treated the condition with the result being a recovery of their lost eyebrows while also bringing their thyroid problem back under control.
Nutrients and Supplements That may Help
Doctors have suggested a natural treatment to reverse the process and this involves taking an iodine supplement. This may be worth trying if you live in an area where iodine levels in the food supply is low. If this is not the case then using iodine supplements will be unlikely to change the problem.
As has been mentioned elsewhere when discussing ways in which eyebrow hair growth can be promoted, introducing more essential fatty acids to the diet will help. Food supplements such as fish oil, flaxseed oil, evening primrose oil and blackcurrant seed oil can all supply essential fatty acids to the body to create better conditions for healthier hair growth to take place.
So the nutrients to increase that may support thyroid hormone production include iodine, tyrosine, zinc and selenium, which are gained from a diet rich in seaweed, protein, nuts and seeds.
While the regrowth of your eyebrows is an outcome that comes as a result of treating hypothyroidism, the main benefit is solving the overriding thyroid problem and overcoming the related health problems.
