I went to Hari's as a model a few months ago and I definitely DON't recommend it! The lady who did my hair was very nice but I don't think she had much experience in cutting my type of hair (afro-mixed race). When I told the hairdresser what I wanted (just a trim), her supervisor came but she didn't even acknowledge me and I was treated as a mannequin rather than an actual human being! I was there for about 3 hours and wasn't even offered a drink of water or anything even though the bar was right behind me. The hairdresser pulled my hair so hard during the blow-dry that I came out of there with a massive headache. My hair was uneven and very puffy. But at least it was free. I still wouldn't go again though, even for free.
After that I went to Jones & Payne also as a model and I had the best haircut I've ever had in my life!
