    TLDR The new hair removal algorithm for skin images works better for detecting and fixing hair, improving melanoma diagnosis.
    The paper presents a novel hair removal algorithm for dermatoscopic images, which is crucial for the automatic segmentation and classification process in diagnosing melanoma. The algorithm uses maximum variance fuzzy clustering for hair extraction and an optimized Criminisi algorithm for hair repair. The study demonstrates that the algorithm improves the accuracy of hair detection by 2-7% and hair repair by 2-5% on average, using the ISIC2019 dataset. The algorithm addresses issues such as the discontinuity and insufficient robustness of the extraction area, the unreasonable priority of traditional hair repair algorithm, weak robustness of repair order, and color deviation caused by too simple selection criterion of sample block in the repair area. The study used 1000 dermatoscopic images containing hair noise, collected from the General Hospital of the People's Liberation Army of China and the ISIC2019 online public dataset.

      The post and conversation are about the role of the enzyme 3alpha-hydroxysteroid reductase in hair loss and the potential of compounds like procyanidin B2 and sulforaphane to boost its activity for hair regrowth. Further research is needed to develop effective treatments based on this theory.

      The user wants to undergo laser hair removal on a bad hair transplant and maintain their natural hairline. They are seeking shampoo recommendations while using finasteride and minoxidil.

      The conversation is a humorous discussion about excessive hair growth due to using minoxidil, with suggestions of laser hair removal and comments on the appearance of the hair. Some users joke about starting finasteride treatment at a young age or being non-responders to hair loss treatments.

      The hair transplant has a straight, unnatural-looking hairline that many find unappealing. The person is not using finasteride or minoxidil, which may affect future hair retention.
