Hair advice toddler boy

My 18 month old is the same his hair is so long and thick tryed to get it cut at the barbers but he wasnt having it so I trimmed it at home with scissors.... Asda little angels have a detangle spray ... I spray a bit on his hair and it helps so much in making his hair tidy it also smells lush a bottle is less then £1 and makes his hair so soft- so if you have an asda near by I'd defo give it a try Xx
