My hair has gone from thick to thinning, frizzy and also very noticeable receding hairline at sides. Any suggestion? (photo)

It has seemed to go dramatically bad within a short period about a month. Hair has gone frizzy,thinking but more annoying sides have receded with hairs become very short.its all appeared very quickly. Scalp also feels very itchy and sometimes feel like a burning sensation as well. Please help find a solution. It may be worth adding that no one else in my family has gone bold or had bad receding hairline including brother,dad and grandad
