I print on 60 degree glass and 60 degree kapton with PLA and hair spray. Verify that you have VA/Crotonates/Vinyl Neodecanoate Copolymer in your hairspray. It seems like every country has only 1 major brand that is brave enough to provide a product that can make hair stronger than steel. Without that ingredient is is said not to work.
Also, I don't have to reapply hair spray every print. It can last a very long time. I haven't actually hit its limit yet. I end up touching the bed about every third print so that forces me to use some glass cleaner and then I reapply the hair spray. (Application tip: don't spray directly on the bed. Spray it on a paper towel and then wipe the area. It will keep your machine from getting crusty.)
