My son started having a horrible time with hair cuts around the age of 2 1/2. He didn't have an issue with the clippers before that. For two years I cut his hair in his sleep. It usually took me about 3 nights to get the whole haircut done. Before that I had tried everything! All of the comments above and when he actually burst blood vessels in his face he got so upset during a hair cut, I decided it wasn't worth it and went to doing it while he was sleeping. I had to do it once he was asleep about 30 minutes but before he had been asleep more than 2 hours. Apparently that's when he is in his deepest sleep. I've now gone back to doing it when he's awake and he does cry but watching TV, talking to him and letting him know how much more I have left to do, letting him sit on my lap while I use the clippers, etc. helps. I still have to cut around his ears and get the bangs straight while he's asleep.... we're trying to work towards being able to go to one of the places with videos games to get a hair cut. I also give him a "reward" for getting his hair cut and I make a big deal of it afterwards. We take pictures, my mom and dad come over to see it, send pics to other relatives.... I know it sounds like a lot but it works for us.... Also, I cut his nails in his sleep. Sometimes I can get all fingers and toes done while he's sleeping and sometimes I have to just do one hand or foot a night. Hope this helps :)

im a hairdresser and I make house calls to disabled and anyone that cant get into a salon for whatever reason. as a mom of an asd child, I have become quite successful in cutting other childrens hair. if you don't have a patient stylist, forget it. the salon is too full of sensory overloads for kids (smells, noises, bright lights, strange people with weird things in their hair, etc). find someone to come to your home. im in north jersey and make house calls ( [[email: (Email address can only be seen by the question and answer creators)).
if you do it yourself, remember, patience and baby steps. so maybe you can only cut the bangs one day. no big deal. try for the back another day. the sides another. if your daughters hair is long enough, pull it in a braid or pony. also, get a childs haircutting kit for them to play with and pretend to cut mommy hair ( you can get the plastic ones online). if all else fails? its only hair. ,no use getting yourself or your child stressed out. one day, they will get a full haircut and look back on allof this and say, wow, that wasn't so bad...

Have u tried cutting it yourself? I have been doing it for the past 4 years since he can't stand the sound of hairdryer. Another option would be to find a hairdresser to come to your house. I found someone recently who is willing to do so at a very reasonable price!!

if the noise bothers him ,my daughter uses earbuds,or little headphones if you can , slowly he got used to it and no longer needs either

My son had melt downs for years getting his haircut. twice we found hairdressers that were great with him and they both left and we would be stuck back at 0 so I started doing it and my husband would hold him down and my son would be scream.
With schools help we found out that it was hurting him with the buzzer going fast and if we take our time and give him a towel to hold over his face because he hates the little pieces of hair on his face. We also let him have brakes for a minute and a big reward at the end if he is good. Sometimes he gets to hold the Ipad. We do not have tantrums anymore but it does take an hour to cut.
