Ishani's hair

Ishani ki baalo se yaad aaya. Her hair is getting thinner day by day. I still remember, her hair was much thicker before. She looked more gorgeous. She looks pretty now too. Her hairstyle is also great. But I was just wondering why she is losing hair. Is that because of using heat?

I am facing the same problem . Maybe it's an off topic question, but please tell me how to regrow lost hair 😭?
