I want you to suggest me the best hair treatment according my hair problem. I have virgin, very long, thin hair with excessive Hair fall. I’m using head&shoulder shampoo since 2019. Never applied conditioner i mean never & never taken oil massage since 2021. Low porosity hair. My hair not break they just fall without hurting my scalp. Blow dry in winters only. Straighten/ curling/ crimping only occasionally like Karwachauth & weddings. After hair wash my hair falls like water drops😅. What treatment should I take. (Anti hair fall spa/ keratin or something else).
