If your doctor has prescribed a chemotherapy drug that is known to cause hair loss, make the decision to prepare yourself for hair loss before treatment begins. Cancer already does a number on a person's self-image, and hair loss can be a seriously devastating side effect. Early preparation can help you cope when your hair begins to fall out.
Many women choose to cut their hair short or shave their heads entirely before hair starts to fall out. It's a lot less shocking to have short clumps of hair fall out in the shower or in your hands, rather than a handful of long strands. Plus, hair tends to come out in uneven patches, and short hair can help to temporarily mask this.
I went straight for a 'buzz cut' but feel with hindsight it would have been a good idea for me to have an in-between cut so it was less shocking.
