This product helps to manage unruly and wavy hair while minimizing damage, making it easier to straighten. When heat from a flat iron is applied, it creates smooth, flowing straight hair. It's a popular item and currently in short supply. I mistakenly purchased this product, thinking it was an oil, and removed the film. Unfortunately, I can't exchange it. Although the film has been removed, the product has not been used. If anyone is interested in purchasing this product, I'm willing to sell it at a discounted price. I purchased it just yesterday. I will pack it carefully and ship it via Kuroneko Mercari Delivery. Please feel free to ask any questions.
