Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Oxidative stress contributes to hair graying and loss as we age.

Hormones, especially androgens, play a big role in acne, but most acne sufferers don't have a hormone disorder. Hormonal treatments, including birth control pills, can be very effective for women whose acne doesn't improve with regular treatments.

Androgens have complex effects on hair growth, promoting it in some areas but causing hair loss in others, and our understanding of this is still evolving.

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.

ICG-enhanced NIR laser therapy may be a promising acne treatment with improvement and no side effects.

The TGM3 gene's promoter region is key for skin and hair cell function and may aid gene therapy.

Mutations in the PADI3 gene are linked to a higher risk of scarring hair loss in women of African descent.

Growth factors are crucial for hair development and could help treat hair diseases.

Mutant mice help researchers understand hair growth and related genetic factors.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

The conclusion is that recognizing hair growth cycles can improve the precision of dietary and health assessments from hair analysis.

TRH stimulates human hair growth and extends the hair growth phase.

Topical drugs and near-infrared light therapy show potential for treating alopecia.

The FOXN1 gene is crucial for developing immune cells and preventing immune disorders.

Human hair follicle cells can grow hair when put into mouse skin if they stay in contact with mouse cells.

Children with scalp fungal infections need proper diagnosis and treatment, usually with antifungal medications, and newer drugs may offer quicker recovery.

Hormones and their receptors, especially androgens, play a key role in hair growth and disorders like baldness.

Effective management of children's hair loss involves accurate diagnosis, various treatments, and supportive care.

The document concludes that understanding and treating hair loss requires recognizing its various types and using appropriate diagnostic tools and treatments.

Hormonal treatments are effective for severe or persistent acne and should be used with other acne therapies, considering potential side effects.

Dendrobium officinale polysaccharides may help with hair growth, skin moisturization, and protection against oxidative damage.

Scientists found cells in hair that are key for growth and color.

Choosing the right shampoo for your hair type is crucial.

EGF and FGF help hair growth by affecting cell differentiation and fiber growth.

Genetic variations affecting skin structure play a key role in severe acne.

Nonablative radiofrequency treatments, especially microneedle and fractional types, can improve acne scars by 25%–75% after 3-4 sessions, with full results in 3 months and some side effects.

Mutations in the KRT85 gene cause hair and nail problems.

The conclusion is that we need more effective hair loss treatments than the current ones, and these could include new drugs, gene and stem cell therapy, hormones, and scalp cooling, but they all need thorough safety testing.

Eruptive vellus hair cysts are a cosmetic skin condition, more common in young adults, with few effective treatments.
