Why is my hair thinning so much?

[LouieGrace]

I am 20 years old and my hair is thinning a lot. I suffered from anxiety and depression late last year when it started, however I feel relatively fine now, yet it is still thinning.
I have visited the doctor and dermatologist, and my bloods come back normal, and the dermatologist said i could have telogen effluvium, however there seems to be little regrowth, and the regrowth that is there is wispy and very thin.

I was wondering if this could be a thyroid problem that doesn't show up on general thyroid tests, or could it be a result from taking MDMA (I have taken probably 20 caps since july last year with a dense period from october to january).
My hair used to be thick and healthy and get greasy within a couple of days after washing, and now it seems to be dry and wispy all the time.

What you have posted is TSH.  Your result is 0.6, and the reference, in parentheses, is 0-4-4.0.  So, your TSH is at the lower end of normal.

The other two tests are thyroglobulin antibodies (TGab) with a result of 21, range 0-60, and thyroid peroxidase (TPOab), result less-than 15, range 0-60.  So, those, while not zero, are within normal limits.  It doesn't look like you have Hashi's.  

Unfortunately, your doctor didn't test FREE T3 and FREE T4.  These are the actual thyroid hormones and much more important than TSH.  TSH is a pituitary hormone, a very indirect measure of thyroid status.  TSH is supposed to accurately reflect thyroid hormone levels in the blood, but that isn't always the case.  So, testing is really incomplete.  

You might ask your doctor to order a complete panel with FT3, FT4 and TSH.  Do you think he'd be amenable?

My thyroid function tests says the following:

THS          27/8/15 - 1.0         07/04/16 - 0.6 mU/L (0.40 - 4.00)
aThyro' gb                             07/04/16 - 21 U/mL (< 60)
aPeroxase                             07/04/16 - < 15 U/mL (< 60)

And that's it. I'm not sure what they mean. I've tried looking online for 'normal' ranges but i guess the abbreviations we're using in Australia may be different? I'm not sure.
Sorry for the late reply. I couldn't get to the doctors until this morning.

Perhaps you could ask your doctor for your results.  Thyroid test results are subject to interpretation.  Ranges are very flawed, and all of us who deal with them know that just being within normal limits is not enough to guarantee we will be symptom free.  Have any of your doctors tested iron?  Deficiency of iron can also be responsible for hair lass.

Please post your thyroid labs so we can see where you fall in the ranges.  Include reference ranges from your own lab report.  

I don't see hair loss as a side effect of MDMA.  Have you found a source that says it is?

Do you have any other symptoms?

I dont actually have the labs, the doctors never particularly gave them to me I don't believe.
And I did have some level of anxiety at the end of last year, where my heart would beat very hard (enough so i could feel it throughout my entire body), and i wouldn't feel satisfied with my full breaths, casuing me to want to yawn a lot. I also had a pretty foggy mind and was quite tired un unmotivated alot. Now its mainly just the hair, and sometimes i can feel a heavy heart beat and ill be foggy for a little bit. But the anxiety has either subsided, or im getting used to dealing with it.
