Trichotillomania help

I’ve been dealing with trich (hair pulling from OCD/anxiety) for the past 3-4 years. Over the past year, new hair growth has caused these weird short patches of hair in the areas that I pull that are really wavy/curly. The rest of my hair is somewhat straight because it’s long, so I just have these weird waves in the front of my hairline and at the top/back of my head. They’re too short to straighten so they usually just stick out. My main question here is are there any hair products like shampoo or something out there that will help straighten these parts and make them blend in with the rest of my hair? Thanks for your help!!
