While chemotherapy drugs can be effective in killing cancer cells, they also damage normal cells that divide rapidly.
This includes:
Keratinocytesare cells in the hair follicles that help produce hairs.
Chemotherapy drugs can enhance that stress to the point that the cell dies.
When Does Chemotherapy Cause Hair Loss?
Hair loss from chemotherapy can begin as early as five days to two weeks after the first cycle.
However, the most noticeable hair loss typically occurs between three and six weeks after starting treatment.
This timeline varies based on individual responses and the specific chemotherapy regimen used.
When Does Hair Loss Grow Back After Chemotherapy?
Hair re-growth typically begins within three months of concluding chemotherapy.
Your hair may initially grow back curlier and with a different texture.
Some targeted therapies may also affect the pigmentation of hair, often causing the hair to become darker.
Wigs, scarves, and hats offer both comfort and style during treatment.
Hairpieces, such as toppers, makeup, and specialty sprays can mask thinning areas.
The decision to embrace hair loss or explore these solutions is entirely personal and up to you.
