Hi all, I am new posting to this website but have been reading with interest for some time!
I have been suffering with hair loss for several months which is getting worse. I had bloods back in oct which were 4.86 tsh and 12 T4 ( they didn't test t3 or antibodies).
I have just started on levothyroxine 50mg. I asked the doctor could my ferritin level if 50 also affect hair loss as my thyroid results were not that drastic to cause so much hair loss ( about 30% of hair is gone, if not more ..) I loose at the root with a white bulb on end and no regrow the. She said no as my ferritin is 50 but some websites say it should be higher? She said she had never even heard of this connection...
I am loosing weight unless I try and increase the amount I am eating and tired all the time.
Has anyone else has experience with hair loss with sub clinical hypothyroidism?
Thank you for any help at all,
Nikki
Welcome to the forum, Niklew.
It seems that ferritin needs to be >70 for hair regrowth. I'm sorry I don't have links to substantiate.
Untreated hypothyroidism is more likely to be responsible for hair shedding. It can actually get a little worse when you first start taking Levothyroxine but should start improving after a few months as your thyroid levels improve. Fatigue will be due to low thyroid hormone.
I experienced unwanted weight loss on Levothyroxine. I was advised to eat frequent small meals to maintain weight. I found protein shakes inbetween meals helpful in gaining some weight.
The goal of Levothyroxine is to restore the patient to euthyroid status. For most patients that will be when TSH is 0.3 - 1.0 with FT4 in the upper range. FT4 needs to be in the upper range in order that sufficient T3 is converted. Read Treatment Options in thyroiduk.org.uk/tuk/about_...
For maximum absorption Levothyroxine should be taken with water 1 hour before, or 2 hours after, food and drink, 2 hours away from other medication and supplements, and 4 hours away from calcium, iron, vitamin D supplements, magnesium and oestrogen.
It takes 7-10 days for Levothyroxine to be absorbed before it starts working and it will take up to six weeks to feel the full impact of the dose. Symptoms may lag behind good biochemistry by several months.
You should have a follow up thyroid test 6-8 weeks after starting Levothyroxine. Arrange an early morning and fasting (water only) blood draw when TSH is highest, and take Levothyroxine after your blood draw.

Thank you for your reply! Oh no I’m dreading more hair loss first .... is this a common side effect of Levothyroxine? my GP refused to test T3 and I asked about iron supplements and she refused saying as it’s within ‘the range’ then not to take any. I have bought some gentle iron 20mg and thought to take 1-2 day to give 40mg elemental iron?
I had bloods last November as I wasn’t feeling well and all come back normal but when I asked this oct what my thyroid was back then it was tsh 3.46 and T4 13 so I think that was prob why. I wish they would analyse bloods better rather than just saying if it’s in the range then it’s fine. I think if they had seen it was higher side of the norm they should have said to retest in 3-6 months..
Thank you again
Niklew,
I didn't say Levothyroxine would cause more hair loss, I was just warning you that it might.
T3 is rarely tested in primary care and not often in secondary care unless TSH is suppressed <0.03. You can order private thyroid tests but I wouldn't bother until TSH is around 1 with FT4 higher in range.
Get into the habit of asking for results and ranges of ALL blood tests. You can always post them on the forum for advice or Google them.
Thank you- you have all been great help. I’m finding the whole hair loss really distressing. I’ve always had fine hair but lots of it but can now visibly see my scalp at the front and sides. I try and wash my hair every 3-4 days as I find it so upsetting.
Thank you for your help. Do you think iron supplements would help at all? Biotin?
Thank you
Niklew,
You could try iron and biotin. Make sure you stop taking biotin a week before ALL blood tests as it can skew results.
