How many chemo treatments until hair loss?

Hair loss typically begins after the first or second chemo treatment, usually within 2 to 3 weeks. However, because different chemo regimens have different side effects, you must discuss this directly with your doctor. They can monitor your reaction and help manage any scalp complications or sensitivity safely.

From the research I've been doing for a family friend, it seems most patients experience hair loss starting about 14 to 21 days after their first treatment, so usually during the second cycle. It varies from person to person, but this seems to be the most common timeline.

Most people notice shedding about two to three weeks after the first treatment, which is usually right around the time of the second session. I remember being so incredibly anxious about this timeline when my relative started chemo, but taking it day by day really helps. Sending you all the positive energy and support.

I am trying to learn more about this because my aunt is starting her therapy soon. Does the hair loss happen suddenly all at once, or is it a gradual thinning over several weeks after the first couple of treatments? I want to know how best to support her gently.
