Hair help - Synthetic Frizziness

Hi everyone :)

So I use wigs to hide the fact is am a late bloomer (mtf) and I inherited both of my grandfather's genetics (it started backing away when I was about 24, I am 38 now); and I am having g difficulty with them. After about 4 or 5 days, they start to get frizzy and wirey. They are synthetic hair and no matter what I do (have tried washing and conditioning, argon oil) they seem to have a very short life, which adds up financially. So I am hoping g the trans experts of reddit can help me out in knowledge of prolonging their lives 😀

Hope you are all having a smashing day and Happy Pride!!!
