2nd Keratin treatment (not so good)

My second keratin treatment I used the Global Keratin Hair Taming System, the results where almost similiar to the Natura Organic Hair Care System. I was extremely happy but then after a period of what I think was about 2 to 3 weeks my hair lost shine, movement and about 35 percent of its volume. I was extremely unsatisfied with my hair and if I can go back in time to stop myself for doing the Global Keratin Treatment I would do it no questions asked. So, in between  the Natura Organic Hair Care System and Global Keratin, Natura wins hands down.
