Have you looked into that texture manageability system by beautiful textures. It supposedly doesn't have chemicals. If you don't care for your current texture this could be an option. I know chime Edwards had it done like a year ago but didn't what her texture to change so she ended up cutting her hair. Check out her YouTube she gives her experience. If you perfer straight hair I would think this would be a good option for you. I think design essentials also has a staightening system as well. There are so many more options today. Your hair should not be stressing you. You shouldn't feel bad preferring straight hair.
Good suggestion! This product kind of reminds me of New Options Alkaline Mineral Softener which I think I'm going to try. It just softens the hair making it easier to straighten and the straight hair style is supposed to last longer.
