Underarm hair removal for nearly 12 year old

[teacherwith2kids]

DD has the first signs of underarm hair. It is fairly invisible at the moment, but as a dancer she is forever in a leotard waving her arms above her head, so will need an efficient method of hair removal as soon as it is even vaguely obvious to anyone else.

As I'm an eczema-y type, shaving has been pretty much the only option available to me. A brief browse in Boots indicated that there are a whole range of hair removal creams out there, including some for sensitive skin and for the underarm area.

What would the least hassle be? It is going to need to be something that can be used regularly.

I bought my 13 yr old daughter (who reacts to creams) a Philip's Ladyshave. Battery run so no cords. Can be used wet or dry. Very easy and quick. Quite difficult to hurt yourself in any way with it. No fuss.

My dd asked about this btw, it wasn't prompted by me. She used to do ballet fairly seriously and takes swimming classes in a mixed group at school. She is very pale skinned but has inherited dh's dark/hirsute genes in terms of body hair. I couldn't talk to my mother about this sort of thing at all, so I was naturally going to help dd when she asked. (Agree with others that it is sad that society is such that teens do feel self conscious about this sort of thing though.)
