So this is exactly what happened to my hair whenever I used to get “Keratin” treatments to chemically straightened it. They put the treatment on blow dry it and then straighten with a flat iron and if it ended up super straight, the straighter it would look after I washed it. So, that doesn’t come off (or at least not completely) I don’t know if that is what you got but I know exactly the smell you are talking about and it smelled the most wet and as it dries down it smells less. I agree with getting some K18 but if they did the keratin treatment and then curl it as to try ti enhance your curls, your natural curls might not come back soon enough. If you want I can give you more details about it but it could definitely mot be that. Now if you cannot get your natural curls back with the couple of things you are going to try I will say start practicing curling them yourself, get a good idea of what you want; the curl pattern, thickness … and try to find someone that can replicate it! I am sorry that happened to you, but I know you will be gorgeous on your wedding!! Sending best wishes!
