Ruby laser pulses best destroy hair follicles during the growth phase and effectiveness varies with laser intensity; melanin is key for targeting, and timing treatments can improve results.

Liposomes could improve how skin care products work but are costly and not very stable.

Melatonin helps regulate hair growth and protects the hair follicle from stress.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

We need more research to better understand human hair follicle stem cells for improved treatments for hair loss and skin cancer.

Skin surface lipids are important for skin health and altering them could help prevent aging and treat skin conditions.

Hirsutism is more linked to high androgen levels than acne or hair loss, and a mix of hormonal tests is best for diagnosis; certain treatments can reduce symptoms.

Male pattern hair loss is genetic and influenced by hormones, with treatments like minoxidil and surgery available.

Male hormones and their receptors play a key role in hair loss and skin health, with potential new treatments being explored.

Growth factors and cytokines are important for hair growth and could potentially treat hair loss, but more research is needed to overcome challenges before they can be used in treatments.

Scientists created stem cells that can grow hair and skin.

Androgens can both stimulate and cause hair loss, and understanding their effects is key to treating hair disorders.

No treatment fully prevents hair loss from chemotherapy yet.

The document concludes that adult mammalian skin contains multiple stem cell populations with specific markers, important for understanding skin regeneration and related conditions.

The Foxn1 gene mutation causes hairlessness and immune system issues, and understanding it could lead to hair growth disorder treatments.

Keratin 15 is not a reliable sole marker for identifying epidermal stem cells because it's found in various cell types.

Liposomes better deliver minoxidil for hair loss treatment than niosomes.

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

Testosterone therapy seems safe for postmenopausal women for a few years, but more research is needed for long-term effects.

Mice without the vitamin D receptor gene lose hair due to disrupted hair follicle cycles.

Hidradenitis suppurativa is caused by genetic factors, inflammation, bacteria, hormones, and lifestyle factors like obesity and smoking.

Menopause reduces skin collagen and elasticity, and while estrogen therapy can help, its risks require careful consideration.

Targeting the skin's endocannabinoid system could help treat skin disorders.

The circadian clock influences the behavior and regeneration of stem cells in the body.

Finasteride, CPA, and flutamide are all equally effective in reducing excessive hair growth in women.

Human hair follicle stem cells can turn into multiple cell types but lose some of this ability after being grown in the lab for a long time.

Niosomes are promising for skin drug delivery, offering benefits like improved drug penetration and stability.
