The document provides a method to classify human hair growth stages using a model with human scalp on mice, aiming to standardize hair research.

Type 2 diabetes, bacterial scalp infections, and tight hairstyles like braids and weaves are linked to a higher risk of a scarring hair loss condition in African American women.

Older adults have a high rate of skin cancers like basal cell carcinoma and melanoma, mainly due to UV exposure and age.

Shampoos are designed to clean and improve hair and scalp health, with specific ingredients for different hair types and conditions.

Sunlight worsens hair loss; protect scalp.

Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.

Different methods of preparing Platelet-Rich Plasma (PRP) can affect wound healing and hair regrowth in plastic surgery. Using a kit with specific standards helps isolate PRP that meets quality criteria. Non-Activated PRP and Activated PRP have varying effects depending on the tissue and condition treated.
