I got my dreads done in a shop but i have done no maintnence, no products, no wax should i shave and star over or let them be

lucky i wish i could of did it that way ive wanted dreads since i was 10 and grew my hair out tell i thought it was long enough and yee im glad i didnt get to fucked for going to a saloon idk there was something that always told me just wash em and let them do what they want so thats what i did i didnt listen to ppl telling me put wax in them palm roll them and mad ppl just sterotyped me he never washes them he's a bum and NO girls that it was attractive but i stuck threw it because ive wanted them for so long and now that i have them ill never cut them off. I met a guy once that tod me he had dreads for 9 years and just decided to cut them off and he's been bald like dr. phill ever since he said the tension and everything caused it but idk... and you ask why would i cosider to cut them off? i never wanted to cut them off i just wanted opinions on it and if it was suggested to cut them off and start over from a person who has had dreads for 20 years i would
