I booked a reservation for my haircut yesterday and went to athe hair salon in thethis morning. I booked a reservation for my haircut yesterday and went to the hair salon this morning.

This morning, this afternoon --> you can use these when talking today specifically. Eg. "This morning I went for a run. This afternoon I will go to the beach." "In the morning" is also OK, but a bit vaguer. A hair salon = any hair salon, nonspecific THE hair salon = the one you booked your appointment at

I have been hirusing the same hairstylist from the beginning until now. I have been using the same hairstylist from the beginning until now.

Even better: "I have been using the same hair stylist since then." or "I have been using the same hair stylist since the beginning." You could also say: "I have been seeing the same hair stylist since then", rather than using. TECHNICALLY you are hiring her for a short period of time, but that's not how I'd phrase it

I have been hirseeing the same hairstylist from the beginning until nowthe whole time. I have been seeing the same hairstylist the whole time.

'Hiring' implies that you employed her and pay her a salary. In English we would just say 'seeing the same hairstylist' or 'I have been going to the same hairstylist'.

I have been hiringusing/going to the hairstylist from the beginning until now. I have been using/going to the hairstylist from the beginning until now.

You can use "and just does it" to cut the repitition of saying "cut my hair" twice. I wouldn't put well here. You could also phrase this as: "She understands what I want..." What you have written is good though! This is just another potential sentence structure you could use another time/elsewhere.

The sentence is understandable, but feels a bit awkward and convoluted. I rewrote this one, hope it makes sense.

I always get my hair cut in a relaxed mood. I always get my hair cut in a relaxed mood.

Better alternatives: "I always feel relaxed when I am getting my hair cut." "I always feel relaxed when I get a haircut." "I always feel relaxed when I get my hair cut."

I always get my hair cut in a relaxed style. / I always get my hair cut when I am in a relaxed mood. I always get my hair cut in a relaxed style. / I always get my hair cut when I am in a relaxed mood.
