How Long Does It Take For Hair To Grow Back After Chemo And Radiation. Oh thats good to know my hair has just started coming back 6 weeks after chemo. But after a year the hair should start growing back again.
That timeline varies from one person to the next but no matter when your hair starts to grow back its going to be fragile at first and your scalp might be sensitive. After around a month or so your hair should begin to grow naturally at a normal rate and after around two months post-chemo you hair will be around an inch in length. Full normal hair growth rates may take up to a month or more.
For radiation therapy hair regrowth will not begin until several months after radiation treatment is completed.
It could fall out very quickly in clumps or gradually. So make sure you treat your hair carefully for the first six months after chemo. For many people hair starts growing back around four to six weeks after finishing chemotherapy. Hair texture usually reverts to the way it was after the effects of chemotherapy radiation or tamoxifen on the hair follicles wears off completely.
