Midely isnt a word, not sure what you meant to put

When I woke up, I clicked the reservation button to makebook an appointment with a famous hair designer’s reservation at a time I want, bywith the girl I want.

“Book an appointment” is the standard collocation

This is the idiomatic expression.

Before I make a change my hair, I had to have an English tutoring class which was held in ther tutor's apartment and lasted for an hour with. The English tutor who has thea certificate ofin English teaching, as toto help us master of English.

Breaking up the sentence makes the ideas much easier to follow.

Getting I-ring perm of my haira perm

I'm not sure what an I-ring perm is. And because a perm is a hairstyle, it's a bit repetitive to state that it's for your hair.

As II'm think of changing my hair to midely, I have toing about changeing my hair as well as my style.

I'm not exactly sure what you meant with the sentence that you wrote. "Midely" is not an English word, so I'm not sure what you wanted to say. I simplified the sentence here to be direct about wanting a new hairstyle.

When I woke up, I clicked themade a reservation button to makewith a famous hair designer’s reservation at a time I want, by the girl I want.

Again, I simplified this a lot.

After making the reservation, I’m waitinged for several hours to get hair change to visit there.

Hmm, not sure what you meant by the last part of this sentence either.

In the class, I did explain by speakingspoke some English,. I have watched the English listen class during going from office to home and make an official letter to make change order to get approval by company.videos in English and listened in class.

Hmm, again the latter part of your sentence is confusing here. Not sure what you wanted to say, so I cut it out for a more concise description.

After explaining that,My teacher said I need to make a foreigner friends to make English skill efficientlyfriends with foreigners to improve my English.

I think it would be good to attend thea regular foreigner’s gathering who really want to make a friends in bBusan, Seomyeon.

"Gonna" is slang basically.
In formal writing, you should always write out "going to"

I tried looking it up, but I don't know what an I-ring perm is! This phrasing should be fine for all perm hairstyles though :)

"midely" - Do you mean mid-length?

When I woke up, I clicked themade a reservation button to make famous hair designer’s reservatiat a famous hair salon at athe time I want, by the girled, with the stylist I wanted.

We "make" a reservation.

After making my reservation, I’m waitinged for several hours to get hair change to visit thero get my hair done.

We go somewhere in order to get our hair "done".

Before I make a chanwent to get my hair done, I had to havego to an English tutor class which held in her apartment for an hour with an English tutor who has thea certificate of English teaching, as tond a master ofs in English. It was held in her apartment for an hour.

The context about the length of the class makes the original sentence too long.

In the class, I did explain by speaking English,in English, I talked about how I have watched the English listen class during going from office to homeing practice during my commute, and makwrote an officiprofessional letter to make change order to get approval byfrom a company.

"going from office to home" --> "commute"

I switched "official" to "professional" because it is a business letter, not a government letter.

After I explaininged that, my teacher said I need to make a foreigner friends to makepractice my English skill more efficiently.

I think it would be good to attend the regular foreigner’s gathering of people who really want to make a friends in bBusan, Seomyeon.

"gonna" is very informal, but not wrong. You could use "I will" instead.
