All of the above words refer to people who cut or arrange hair. A 'barber' refers to someone who specifically cuts men's hair, whereas the other two words may be for either sex. The word hairstylist is usually associated with women however.

The work of a hairdresser or hairstylist is to make people's hair neat and beautiful. They usually cut, color and style hair in many different ways.
The word "hairdresser" can also be used to describe the place that you go to to get your hair styled.
A person that cuts and styles hair may be called a hairdresser or a hairstylist. We usually use these terms for a person that does women's hair. A person that specializes in cutting men's hair is usually called a "barber".
You may use these terms in the following ways:
-I made an appointment with the hairdresser at the salon for Thursday at 10 am.
-I have always wanted to be a hairstylist because I love working with hair.
-My barber wasn't available to cut my hair today, so I'm going to cut it tomorrow.
「美容師（髪の毛を切り整えてくれる人）」は英語では 'hairdresser' または 'hairstylist' と言えます。普通これらの語は、女性の髪の毛を切る人を表します。男性の髪の毛を切ることを専門とする人は "barber"（理髪師）と呼ばれます。
これらの語は次のように使うことができます。
-I made an appointment with the hairdresser at the salon for Thursday at 10 am.（木曜日の午前10時に美容院を予約しました）
-I have always wanted to be a hairstylist because I love working with hair.（髪の毛を扱うのが好きなので、ずっと美容師に憧れていました）
-My barber wasn't available to cut my hair today, so I'm going to cut it tomorrow.（今日はいつもの理髪師さんが空いていなかったので、髪の毛は明日切りに行きます）
All three of these different occupations sort of have the same meaning and can be used interchangeably. The one main difference between these is that the word, "beautician," can refer to someone who does other styles of body treatments as well such as nails and/or other beauty treatments such as makeup, etc.
