Structural and Pigmentary Characteristics of the Skin in Hairless Dog Breeds

Topical application of Eriodictyon angustifolium extract can prevent and reverse age-related beard graying and darken gray hair by increasing melanin production. Sterubin, a component of the extract, also promotes hair pigmentation and protects cells from DNA damage.

Male-pattern baldness might increase UVB exposure on the scalp, potentially affecting vitamin D and skeletal health. The hypothesis is debated, with some seeing it as a minor benefit in specific contexts.

Hot weather can increase hair shedding, possibly due to dehydration and active sebaceous glands. Using shampoos with salicylic acid or zinc pyrithione may help; daily anti-inflammatory use is not recommended.

A 30-year-old woman with a history of anemia and low vitamin D experienced hair shedding, which improved after addressing nutrient deficiencies. Despite regrowth of terminal hairs, her dermatologist recommended treatments like minoxidil and spironolactone to prevent future bald spots, but she is cautious due to family history of hormone-related cancers.

Astaxanthin may cause increased hair shedding, affecting even transplanted hair and eyebrows. The user has tried various treatments for androgenic alopecia, including minoxidil, finasteride, and RU58841.

The conversation discusses hair thinning potentially caused by seborrheic dermatitis, with the user considering over-the-counter treatments like Head and Shoulders, Selsun Blue, and Nizoral, while maintaining keratin-treated hair. A suggestion is made to use raw organic honey as a hair mask to treat seborrheic dermatitis without affecting keratin treatments.
