A lot of my friends have been getting pregnant and having kids lately. Are yours too? It's always a guessing game what their hair will be like when they grow up. My hair was straight until I hit puberty and I have friends who had ringlets as babies and now have stick-straight hair. Most women lose a lot of hair 4-8 months after giving birth and some women's hair turns curly or straight after having babies.
I read somewhere that all the cells in our bodies regenerate themselves every 7 years. Hormones and health play a big part in hair texture, but one can assume our hair texture will also change every 7 years. For most it's not drastic but I do think it's true. Have you noticed that?
