KRT31 KRT31 Keratin, type I cuticular Ha1 is a protein that in humans is encoded by the "KRT31" gene. The protein encoded by this gene is a member of the keratin gene family. As a type I hair keratin, it is an acidic protein which heterodimerizes with type II keratins to form hair and nails. The type I hair keratins are clustered in a region of chromosome 17q12-q21 and have the same direction of transcription. Model organisms have been used in the study of KRT31 function. A conditional knockout mouse line called "Krt31" was generated at the Wellcome Trust Sanger Institute.
Hair loss embroidery is another option which involves the use of a blade to add pigment to the eyebrows. This gives a natural 3D look for those who are worried about an artificial look and it lasts for two years. Micropigmentation (permanent makeup tattooing) is also available for those who want the look to be permanent. Treatments for the various forms of hair loss have limited success.
