We would NEVER recommend stopping this life saving therapy, or any other chemotherapy, but utilizing hair loss treatment simultaneously has been shown to decrease or slow down further loss, and in some cases help regrow what has been lost.
We have found that it is important to start treatment immediately after the treatment ends and remission is documented, however, we have had success treating a limited number of patients who had had chemotherapy or radiation several years before. As long as there are hair follicles present on trichoscopy during our evaluation, then treatment will likely help with some recovery.
Fortunately, survival rates of nearly all cancers are improving, but now we need to be sensitive and respectful of how permanent hair loss can affect men and women as they recover.
