Smoothening Keratin Shampoo(200ml)

I'm a huge fan of the smoothening shampoo. I have really thin hair, and a lot of hairfall with my scalp exposed at points, my scalp is also pretty oily. Other shampoos had made my scalp itch, and good shampoos are very expensive. However this one is so gentle, keeps my scalp clean for atleast 4-5days, and definitely helps with reduced hairfall as it makes the hair pretty gentle and easy to manage, leading to less tangles. I hope this continues as I was pretty anxious not to find it on any other platform, but the homesite is quite good and shipping is fast. Thank you!
