  • The Thing I learned Today I didn't Know Yesterday

    Researching curly hair issues, product shortfalls and possible formula vectors today I learned that some “curlies” do not exhibit curly hair until after puberty. No matter if the homo sapiens is female or male. They have mostly straight hair until then and most often the hair transitions to Type 2C or 3A at most. Does anyone out there in this blogosphere have personal experience with this phenomenon? How did I live so long without knowing this?

    Hello, “fresh” member here😀 I’ve seen up-close two very different cases: a friend’s daughter whose straight hair went “Shirley Temple” when she was about 12-13y, and another friend, whose almost “afro” hair went straight in the process of giving birth (the doctors blamed the stress factor). So yeah, Mother Nature is something…

    Hello @chemicalmatt ! HUGE thank you for all the amazing info you have contributed to this forum. I appreciate your expertise and experience very much and make a point to look for your responses. I have learned a lot from you and am very grateful! 🙂

    To answer your question… I have experienced this firsthand. I had stick-straight, type 1A hair my entire life. I am now 51, and about a year ago my hair turned wavy/curly. I’d say it’s type 2b but with some ringlets. I have had to relearn how to manage my hair because it’s so very different now.

    My understanding is the shape of the hair shaft determines whether hair is curly or straight, but what makes the shaft change shape (esp after 50 years)?? Given my age, I would guess hormones, which would also explain why some people experience a change in hair shape following puberty.
