Same product but different experience at second time
Here’s a clean and corrected version of your review: “I have used this hair serum before and it worked really well for me. It gave my hair a smooth texture and was very effective. However, this time I ordered it from Amazon, and the product quality seems completely different. It doesn’t provide any smoothness or texture at all, and it feels like it’s not working. I’m not sure what went wrong, but this experience has been disappointing.” If you want, I can make it sound more strict (for complaint) or more casual (for social media).

For fine or straight hair
Super lightweight best for fine hairs. The fragrance is good. It's not oily. Gives you the shine.

Frizz free
This is my 4th time purchasing this serum. Unlike others, it makes my hair smooth and reduces frizz without giving an oily look. The fragrance is also good. A small amount lasts for many hour. I Highly recommended this!
