Be careful with hair growth supplements containing iodine or kelp.
Kelp is a natural source of iodine, and while iodine is essential for thyroid hormone production, more isn’t necessarily better.
If you have Graves’ disease (an autoimmune thyroid condition that causes an overactive thyroid), excess iodine can aggravate hyperthyroidism and potentially worsen thyroid symptoms.
Considering thyroid dysfunction itself can contribute to hair loss, adding high-dose iodine without knowing what’s happening with your thyroid is not a clever move.

Because hair loss isn’t something you fix by throwing a handful of trending supplements at it. And sometimes, the ingredients marketed to support hair growth aren’t appropriate for everyone.
Always check what’s actually in your hair supplements. 🤎
