Sure, here's a revised version without the use of "OMG":
"Wow, my experience with Simone at the hair salon was absolutely incredible! She gave me a thorough consultation, understood exactly what I wanted, and made me feel so comfortable. Simone's skills and attention to detail were amazing. After 4 hours, I was in complete shock because I absolutely loved my hair! I highly recommend Simone. She's a talented stylist who deserves all the appreciation. Trust me, you won't be disappointed!"
Demi is always so understanding and skilled when it comes to helping me get the style I want. She's really helpful in suggesting possible approaches for my natural curls as well as advice for wearing my hair straight. She's always a lot of fun to chat to as well!
