The parlour owner Renu, along with her three children-- Surbhi, Jivesh and Ankit jumped off when they saw smoke coming out from the salon in the ground floor.
Three of them sustained injuries due to the fall and were admitted at a local hospital where their condition is stable.
Six fire tenders took two hours to douse the fire, which was caused by overheating of old wiring in the building, Fire Station Officer Sanjiv Kumar Yadav said.
