Can Hair Loss be Caused by Thyroid Problems or Fluctuations in Hormones?

Q: One of the things that I have noticed as a person who has needed to take thyroid medication for a long, long time, is that when my thyroid gets a little bit out of balance – when I’m not getting quite enough, I begin to notice is that my hair starts falling out. What about the role of thyroid for hair loss? — T.K., Mineola, NY

A: Both increases and decreases in thyroid levels can cause hair loss and changes in the levels of thyroid hormone can change the consistency of one’s hair. Elevated hormone levels cause scalp hair to be fine and soft, with diffuse thinning being relatively characteristic.

When thyroid hormone levels are low, the hair becomes dry, coarse, and brittle. Hair loss can be either patchy or diffuse (involving the entire scalp).

After Hair Transplant, Can Donor Hair Become Frizzy and Dry?

Q: Why can donor hair become frizzy and dry once transplanted? — G.F., Stamford, C.T.

A: Frizzing and kinkiness is a temporary phenomenon that is part of the normal healing process after a follicular unit hair transplant.

During the healing process, the new collagen that forms around the grafts can alter their growth. Over time, usually within a year, this collagen matures and the hair quality usually returns to normal.

If grafts have been excessively traumatized or grafts larger than follicular units have been used, these changes are more likely to be permanent.
