TLDR Lipids are important for healthy hair, but their exact role is not fully understood and needs more research.

The document reviews the composition, classification, and factors influencing human hair, emphasizing the role of lipids, which, despite being present in lower quantities than proteins, are crucial for maintaining hair texture, preventing breakage, and retaining moisture. Hair damage can be caused by environmental factors, hair treatments, and daily care practices that may degrade proteins, pigments, and lipids, leading to dry, brittle, and dull hair. The paper aims to enhance understanding of hair's physical and chemical properties to aid in the development of hair care products tailored to different hair conditions and cleansing needs. However, the exact function of hair lipids is not fully understood and remains a subject of debate, indicating a need for further research.

in Research 692 upvotes 1 month 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.
