Hair changes?

I am 37 years old, all my life I have had curly hair, ringlets, that is until about 2 months ago. I got my hair cut as I do about every 6 months, and I cut it short which I have had done before, but this time it was different. It stopped curling, I would now say my hair is straight. I have to work very hard to get it to curl just a bit. I hate it! I miss my curls and I miss my frizz.

My hair dresser was stumped and said maybe it has just changed. I don't buy that, hair doesn't go from extremely curly to almost straight. I also don't think a cut can change the texture of your hair. So I started wondering if it was the medication I am on. I take hydroxychloriquine. I did some googling and found two cases where people said they went from straight to curly hair but not much evidence. So I emailed my nurse and she spoke to my doctor, they said I could try two weeks not taking the drug and see if that helps - it has not. I don't personally think 2 weeks is long enough to get the drug out of my system an allow changes to happen. I also don't feel like they would take it as a serious issue/side effect if it was the medication.

Has any one else experienced anything like this? It is all I can think about, people are commenting asking me what happened to my hair and I can't do anything about it. I am growing it again in hopes this new straight hair looks better longer. I just hate this new hair, it is limp and lifeless.

Any help would be appreciated, I would like to go armed with information when I approach my medical team next.
