How much damage does a diffuser do?

I wear a weave , Indian curly (I have 4c hair) and I was wondering how much damage I would be doing to my braids underneath by diffusing the extensions . Any help is appreciated

It depends on the heat setting. If you keep the heat low, it doesn't do much damage. After a while, it could dry out your hair, so just keep your hair as moisturized as possible.
a diffuser lessens the damage of curls from the heat however you should not use it everyday because the more you use the diffuser the more it can dry out your hair and  be as much damaging as a flat iron or blow dryer without the heat
I was just going to say that, Jessi!  Put the heat setting on low and you'll be ok.
