Born in Tel Aviv, Hasson studied for a BA in government and public policy at IDC Herzliya. He joined the Betar movement, and was head of the national leadership of its youth movement between 1998 and 2001. In 2001 he became chairman of the Council of Israeli Youth Movements, a position he held until 2003. Between 2001 and 2005 he also served as an adviser to Prime Minister Ariel Sharon. In 2004 he became chairman of the Likud youth, but left in 2005 to join Sharon's new party, Kadima.
Hasson was placed 29th on Kadima's list for the 2006 elections, and with Kadima winning 29 seats, he was elected to the Knesset. During his first term he served as chairman of the Lobby for the Advancement of Young People in Israel and the Lobby for the Protection of Animals (which he established), as well as being named chairman of the coalition, Kadima's Parliamentary Group Chairman and the party's whip. His advocacy for animal welfare earned him support among Israeli green activists.
He retained his seat in the 2009 elections, for which he was placed 11th on the party's list. Hasson gained a reputation as a socially oriented MK. He led the legislation to ensure widows of fallen IDF soldier who remarried will still get benefits, as well as a law limiting parking lots' prices.
Shortly before the 2013 elections he left the party to join Hatnuah, which he, along with Shlomo Molla, helped Tzipi Livni build. He was placed seventh on the Hatnuah list, losing his seat as the party won only six seats. In 2015, Livni tapped him to fill the 16th spot (reserved for Hatnuah members) on the Zionist Union list.
