If you have Seborrheic dermatitis with sticky, waxy hair, the main treatment is to control scalp oil and yeast overgrowth using medicated anti-dandruff shampoos (such as those containing ketoconazole, zinc pyrithione, or selenium sulfide) used 2-3 times a week, leaving the lather on the scalp for a few minutes before rinsing; during flare-ups, a doctor may also prescribe short-term anti-inflammatory lotions or mild steroid solutions for the scalp. Continue taking Eltroxin as advised for hypothyroidism, as stable thyroid levels support overall hair health, but note that scalp symptoms are usually not directly caused by thyroid disease. Tablets like Scalptone and homoeopathic medicines have limited scientific evidence for this condition, so they should not replace proven treatments. Regular gentle hair washing, avoiding heavy oils or hair products that can worsen the waxy feel, managing stress, and maintaining a balanced diet can also help; if symptoms persist or worsen, consult a dermatologist for a tailored treatment plan.
