My Hair Loss Started When I Began Using New Shampoo

hi doctor,
I am a serious victim of hair loss and I am really worried. I am only the age of 19. My hair started to fall since the time I started using the head and shoulder shampoo about a month ago. After I realise that my hair fall was because of the shampoo so I stopped using it 15 days ago. In this 15 days my hairs have fallen like a waterfall from my head. In my family only my grandfather is bald. Before using the shampoo my hair was quite thick. After avoiding using the shampoo my hair still falls. When the water is poured in my head I could really see my hairlines. I am really worried. Please help me. Will my hair grow once again?

A few things that stand out to me:

• You’re at the age where it wouldn’t be unusual to see the genetic hair loss process start
• You have a family history of hair loss
• You’ve diagnosed your problem as being caused by shampoo

Shampoo isn’t going to cause hair loss unless perhaps you have an allergy to an ingredient. There’s a thread on this site about Head and Shoulders shampoo with hundreds of comments from people, but I really wouldn’t expect this commonly used shampoo to cause the hair loss you’re seeing. See a dermatologist for an examination.
