13 Possible Causes for Elongated Hair Shafts

  • Palmoplantar Keratosis

    Hair appeared to have less pigment and hair shafts were thin when observed under a light microscope. Therapy with oral zinc did not improve the condition at all.[doi.org] Histopathology examination of the lesions showed thick layer of keratosis, parakeratosis, thickened granular cell layer, acanthosis and irregular elongation of rete ridges[doi.org]

  • Syphilitic Alopecia

    Direct microscopic exam of the hair shaft Anagen hairs: elongated, distorted bulb with root sheath attached Telogen hairs: rounded bulb, no root sheath Exclamation point hairs[unboundmedicine.com] Diagnostic Procedures/Other Light hair-pull test: Pull on 25 to 50 hairs; 6 hairs dislodged is consistent with shedding (effluvium, AA).[unboundmedicine.com] : club-shaped root with thinner proximal shaft (AA) Broken and distorted hairs may be associated with multiple hair dystrophies.[unboundmedicine.com]

  • Alopecia

    Basic fibroblast growth factor (b FGF) promotes the proliferation of cells of papilla in vitro, and therefore, plays a key role in hair shaft elongation ( 14 ).[doi.org]

  • Aplasia Cutis Congenita

    Rakowska et al. described a radial arrangement of hair shafts, visible elongated hair bulbs with darkly pigmented proximal ends through the semitranslucent epidermis, prominent[ijtrichology.com]

  • Netherton Syndrome

    Light microscopy of hair shaft from scalp and eyebrows showed pili torti [Figure 3], which confirmed the diagnoses of netherton syndrome.[ijtrichology.com] Figure 2: Epidermis showing mild spongiosis and focal lymphocytic exocytosis, regular elongation of rete edges, moderate parakeratosis and supra papillary thinning.[ijtrichology.com] Skin biopsy showed acanthosis, mild spongiosis, focal lymphocytic exocytosis in the epidermis, regular elongation of rete edges, moderate parakeratosis and supra papillary[ijtrichology.com]

  • Essential Hirsutism in Women

    Exposure to carnitine stimulated hair shaft elongation and reduced hair cell death in this study.[ovarian-cysts-pcos.com] L-Carnitine The University of Lubeck in Germany conducted an experiment on human hair. They discovered that l-carnitine promotes hair growth.[ovarian-cysts-pcos.com]

  • Pediculus Capitis Infestation

    Eggs (commonly called nits) appear as white ellipsoidal operculate bodies (0.8 x 0.3mm) which are glued to hair shafts.[parasite.org.au] The louse clings to the hair shaft by its 6 claws and rapidly moves from hair to hair.[dermnetnz.org] Adult lice have elongate dorsoventrally flattened bodies (2-4mm long) which appear opaque although darker internal organs can be seen mainly in the abdomen.[parasite.org.au]

  • Ingrown Hair

  • Pili Torti

    Light microscopy of hair shaft from scalp and eyebrows showed pili torti [Figure 3], which confirmed the diagnoses of netherton syndrome.[ijtrichology.com] Figure 2: Epidermis showing mild spongiosis and focal lymphocytic exocytosis, regular elongation of rete edges, moderate parakeratosis and supra papillary thinning.[ijtrichology.com] Skin biopsy showed acanthosis, mild spongiosis, focal lymphocytic exocytosis in the epidermis, regular elongation of rete edges, moderate parakeratosis and supra papillary[ijtrichology.com]

  • Cilostazol

    Furthermore, it promoted hair shaft elongation ex vivo, with increased proliferation of matrix keratinocytes.[ncbi.nlm.nih.gov] Additionally, hair shaft elongation was measured using ex vivo hair follicle organ cultures, and anagen induction was evaluated in C57BL/6 mice.[ncbi.nlm.nih.gov] Cilostazol not only enhanced the proliferation of human DPCs but also regulated the secretion of several growth factors responsible for hair growth.[ncbi.nlm.nih.gov]
