I had a Global Keratin treatment done at Miles Wilson in May 2010. Seemed quite expensive at the time but I was impressed with the results. My hair was smooth and frizz free - even went on a tropical holiday and didnt frizz at all. Nearly 6 months later I am still seeing the benefits and spending a lot less time doing my hair. I'll be going back for a second treatment in about a month. I am always happy with my hair cuts by John at Miles Wilson and glad I took their advice on this treatment.
