I am glad that you have been able to talk to your husband @sazbe It's really important that you be able to express your anxieties with your support person.
Where are you going for chemo? Before getting your hair cut, you may want to investigate whether you can access cold caps. I went to Calvary North Adelaide and they do offer them. I gave it a go and for me unfortunately, it didn't work well enough so I didn't continue - that was when I clipped my hair. However, if you don't want to be bothered, there's going to be hair shaving around for blood cancers soon! I believe they'll be using long lengths for wigs and short lengths for environmental clean up brushes.
Best wishes for your treatment.
