What is happening to my hair!?

[HokusPokus]

I washed my hair a few days ago and excessive strands of hair being washed away or covering my hands. I have always had healthy hair that never fell more than 5-10 a day. I have been using excessive hair spray with alcohol content for styling my heavy hair and do not wash my hair more than once in 10 days. I dont understand what is happening to my hair. I am just 22 and this sudden loss of hair and these bald patches are freaking me out!!
They are precisely at the front where I part my hair and one at the crown.
Someone please tell me what is wrong and how can I cure it!
