I haven't read the keratin story by allure

I had my hair straightening with the mild formula that without those fumes, there was no formaldehyde...... or any strong chemicals. My hair after 3 months still better than before the treatment; I did not had any other treatment and after 4 days I could tinted may hair without any damage. My hair now is strong and thick. The kind that they use on my hair was like water with no odor at all; I was 4 days without wash after the treatment and my pillow case didn't smell.
