AIBU To Think Highlights Would Add Volume To Fine Hair?

[DBD1975]

Hello Mumsnetters

Would appreciate some advice about hair.
I have really thin, fine hair which always looks flat and has no natural bounce or volume

I am at a loss to know what to do to try and do to improve the situation. I am happy with the colour (light blonde) but the lack of body is really noticeable and my hair is so fine in places you can see my scalp.

I don't know if having some highlights would add volume so my question is would it be unreasonable to think highlights would add volume/definition?

Any advice gratefully received, thank you.

I also have very fine hair. I do have highlights, I can't say it's really added volume but it does look thicker, maybe the dimension of the colour? Some people's hair texture changes a bit when it's lightened but mine hasn't, it's still exactly the same.
