Detailed Answer:
Hello ma'am and welcome.

Thank you for writing to us.

I have gone through your query with diligence and would like you to know that I am here to help. Thinning of hair is associated with hypothyroidism (under functioning thyroid) and will require management in the form of oral medications (e.g. levothyroxine).

So the best way to avoid loss of hair and thinning is with the help of those oral medications to manage your hypothyroidism at the earliest. Please visit a doctor for further management if you have not already done the same.

I hope you find my response helpful. Please feel free to write back to me for any further clarifications, I am always here to help.

Best wishes.
