    TLDR Using a blow dryer in a certain way can cause localized hair damage with bubble formation inside the hair.
    A 23-year-old white woman experienced a sudden breakage of hair along her anterior hairline after shampooing, which was attributed to her hair styling technique involving a hot air blow dryer and a round brush. Physical examination revealed an oval-shaped area of coarse, crinkled, shortened hairs, without signs of alopecia or scalp infection. Light microscopy of the broken hairs showed multiple bubbles within the hair shafts, some causing distension, but no trichorrhexis nodosa was observed. This case suggests that the use of a blow dryer in a specific manner can lead to localized hair damage characterized by bubble formation within the hair shafts.

      A user who shared progress pictures of their scalp using a microscope camera, demonstrating the difference between healthy and miniaturized hair. Various explanations for the cause of this were discussed, such as DHT build-up in scalp sebum causing an autoimmune response leading to inflammation and eventual hair loss, with some suggesting a do-it-yourself treatment involving adding ascorbic acid powder to shampoo.

      Hair loss may be caused by calcification of capillaries in the scalp, restricting blood flow to hair follicles. A daily treatment regimen including high doses of Vitamins D and K, Magnesium, and Nattokinase could potentially decalcify these capillaries, improving blood flow and hair growth. However, some users warn against excessive Vitamin D intake and emphasize the need for medical consultation.
