I was recommended to Henri by a friend of mine. He first styled my hair which I loved. He then suggested I do a Keratin Treatment by Coppola which he said is formaldehyde free. I went back a week later to do the treatment and could not believe the results. My curls are looser and softer that before, but the best part about it is, I no longer have any frizz at all. First time in my life I really love my hair.
