Pandas write field names when exporting CSV Python

I'm programming a little development, but I have problems writing to a CSV I don't want panda to write the name of the fields, but I couldn't remove this option, I read the documentation and added the argument "index_label=False" and "index=False " when exporting the file as follows:

   import pandas as pd

    a=[1,2,3,4,5]
    b=[6,7,8,9,10]
    expHISTORIA=pd.DataFrame([a,b]).transpose() #crear DataFrame
    expHISTORIA.to_csv('Historias.csv',index=False,index_label=False, mode='a',sep=';') #crear el CSV

The problem is that the generated file contains fields, I want it not to print them, it only generates the file with the data.

What it prints is the following:

   0    1
   1    6
   2    7
   3    8
   4    9
   5    10

But the first two numbers are (0, 1) are fields that are created automatically and I don't want them to be there. Ideally it would print this:

   1    6
   2    7
   3    8
   4    9
   5    10
