Currently I'm 18 back 3-4 years I moved to another city so before that I used to had straight silky and soft healthy hair but after changing city there used to be hard water and I think it was not a big problem but then I used park Avenue beer shampoo which suddenly damaged my hair since then my hairs like wavy, very hard and rough like jute and dull it's obviously damaged, I tried consulting my family derma but he didn't gave a shit, he said it's normal and good but I want old hair type back although my scalp used to be oily and had scalp acne but since few it's not that oily and yeah no scalp acne. Please I want a cure of it🙏
