Coloring Hair After Chemotherapy

How soon after chemo is it safe to dye the hair??

If the hair has not fallen out and you have passed that critical phase where it would normally fall out, then you can use a gentle semi-permanent dye to color your hair. Semi-permanent dyes that are acidic are made of small molecules which can pass through into the cortex of the hair. As all of these dyes are water soluble, they can be easily washed out. They may last for between 1-6 weeks depending upon what dyes are used, but they lose their effectiveness with frequent washings. These are generally safe and can be used at home. Since these do not contain bleach they can not lighten the hair, but darkening gray hair is reasonable.
