Since your testosterone and thyroid levels are healthy, we can look at other factors. Topical minoxidil is a medically recognized option that some men use off-label to stimulate facial hair follicles. Additionally, high stress and depression elevate cortisol levels, which can indeed temporarily disrupt hair growth cycles. Managing stress and focusing on mental well-being can naturally support your hair growth. I highly recommend discussing topical minoxidil and stress-management strategies with your doctor to find a safe plan.

Since your TSH is still 7 mIU/L, your current levothyroxine (Thyronorm) dose of 25 mcg may be too low and might need to be adjusted by your doctor. Additionally, progressive weight loss to 37 kg is atypical for hypothyroidism and requires careful evaluation. I highly recommend visiting your healthcare provider soon. They can discuss adjusting your levothyroxine dose and run tests to check for nutritional deficiencies, iron levels, or absorption issues that could be causing these symptoms.

The i-pill (levonorgestrel) contains a high dose of hormones which can cause temporary fluid retention and bloating, mimicking rapid weight gain. This is temporary and typically resolves within a few days. While you are taking Thyronorm (levothyroxine) for your thyroid, a single dose of the emergency contraceptive will not cause permanent weight gain or disrupt your thyroid function long-term. If you continue to experience weight changes or feel unwell, it is a good idea to have your thyroid levels checked by your doctor to ensure your dosage is still correct.

It is unlikely that pure paracetamol caused your increased heart rate. However, many cold remedies combine paracetamol with decongestants (like pseudoephedrine or phenylephrine). These decongestants can interact with your thyroid medication (Thyronorm), causing a rapid heart rate. This reaction is usually temporary and not dangerous, but you should stop taking that medication. Please check the ingredient label. For safe cold relief, you can take plain paracetamol, use saline nasal sprays, or try steam inhalation. Avoid multi-symptom cold products containing decongestants. If your rapid heart rate persists or you feel dizzy, please consult your doctor.

Your TSH of 8.4 mIU/L is elevated, which indicates your thyroid is still slightly underactive, though your negative anti-TPO result is highly reassuring. Because your TSH is high, your current 50 mcg dose of Thyronorm (levothyroxine) likely needs to be increased rather than decreased to help bring your levels back into a healthy range. Please consult your doctor or endocrinologist so they can safely adjust your prescription based on these results.

Since you have been taking Thyronorm for your thyroid, the first step is a simple blood test to ensure your thyroid levels are currently stable, as fluctuations can trigger hair shedding. For your oily scalp and winter dandruff, using a medicated shampoo containing ketoconazole or zinc pyrithione twice a week can help clear the scalp environment. Finally, I highly recommend consulting a dermatologist. They can evaluate the thinning on top and discuss effective options like topical minoxidil or specific vitamin supplements to safely encourage regrowth.
