TLDR "TRICHOASSIST" is a system that analyzes hair and scalp images to help diagnose scalp diseases.

The study discusses a system called "TRICHOASSIST" that uses image processing to analyze hair and scalp features, aiding in the diagnosis of scalp diseases like alopecia and telogen effluvium. The system allows professionals to upload or take images of the scalp using a dermatoscope. These images are then enhanced through various techniques such as resizing, sharpening, denoising, blurring, gray scaling, binarization, and morphological changes. The enhanced image is then analyzed to extract parameters like hair length, hair thickness, number, and density of vellus and terminal hair, and white spots. The system generates a comprehensive report of these parameters, which can be compared with previous reports to monitor the condition over time. This cost-effective system can assist practitioners in diagnosing diseases and taking effective preventive and curative measures.

community Diffuse hair loss and scalp biopsies

in Research 692 upvotes 4 months ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

community I feel like people here shrug off nutritional issues too quickly. Particularly for Retrograde Alopecia.

in Chat 8 upvotes 1 year ago

The user believes Retrograde Alopecia may be linked to vitamin imbalances, specifically from taking too much Vitamin E, A, Zinc, and Selenium, and suggests it could be a middle ground between Androgenic Alopecia and Telogen Effluvium. Treatments for hair loss mentioned include Androgen inhibitors and improving lifestyle factors like nutrition and sleep, with topical melatonin also recommended for Retrograde Alopecia.
