So I love this bonnet, its comfy, it's cute and after some trial and error and a panic message to the owner of the business, of which I got a very quick reply, I was able to figure it out quickly and use it accurately. This has helped with many of my issues with my scalp which surprised me a bit given that's not even it's purpose. My hair comes out every morning looking glorious and feeling soft. The lack of frizz and irritation on my scalp is the most noticeable effect. I'm so happy with this purchase and glad I waited to purchase from this wonderful business instead of buying something cheaper elsewhere. Worth every cent and will be used for likely years to come. Next purchase will likely be a satin lined shower cap.
